==Biography==
Kao was born in [[Shanghai]] in 1933, but his [[ancestral home]] is in [[Jinshan District|Jinshan]], [[Jiangsu]] now part of Shanghai. He studied [[Chinese classics]] at home with his brother, under a tutor.<ref>{{cite news|url=http://why.eastday.com/q/20091008/u1a639015.html|title=Interview of Kao's cousin (诺贝尔得主高锟的堂哥回忆:他儿时国学功底很好)|date=2009-10-08|accessdate=2009-10-09|publisher=青年报|author=范彦萍|language={{zh icon}}}}</ref> He also studied [[English language|English]] and [[French language|French]] at an international school in Shanghai which was founded by a number of progressive Chinese educators including [[Cai Yuanpei|Cài Yuánpéi]] ([[:zh:蔡元培|蔡元培]]).<ref>{{cite news|url=http://oldepaper.zgkqw.com/html/2008-06/01/content_118747.htm|title= 著名女教育家陶玄 Famous Female Educator 陶玄|date=2008-06-01|accessdate=2009-10-09|publisher=绍兴县报 Shaoxing County News|author=陶家骏|language={{zh icon}}}}</ref>

Kao's family moved to [[Hong Kong]] in 1948<ref>[[Phoenix Television|Ifeng]].com: [http://news.ifeng.com/hongkong/200910/1007_19_1377947.shtml 香港特首曾荫权祝贺高锟荣获诺贝尔物理学奖]</ref> where he completed his secondary education ([[GCE Advanced Level|advanced level]]) at [[St. Joseph's College, Hong Kong|St. Joseph's College]] in 1952. He did his undergraduate studies in [[electrical engineering]] at [[University of Greenwich|Woolwich Polytechnic]] (now the [[University of Greenwich]]),<ref name=Woolwich>{{cite news|url=http://www.greenwichalumni.co.uk/magazine%20pdfs/meantime_alumni_spring2005.pdf|title=meantimealumni Spring 2005|accessdate=2009-10-07|publisher=University of Greenwich}}</ref> obtaining his [[Bachelor of Science]] degree issued by the [[University of London]].

He then pursued research and received his [[Doctor of Philosophy|PhD]] degree in electrical engineering in 1965 from [[University College London]]<ref>{{cite news|url=http://www.ucl.ac.uk/research/facts/|title= University College London (UCL) Facts and Figures|date=Page last modified on 30 October 2009|accessdate=2009-11-06|author=UCL}}</ref> (under Professor [[Harold Barlow]]) as an external student while working at [[Standard Telecommunication Laboratories]] (STL) in Harlow, England, the research centre of [[Standard Telephones and Cables]]<ref>{{cite news|url=http://www.iftf.org/node/3144|title= Former IFTF Board Member|date=2009-10-20|accessdate=2009-10-31|author=Lisa Mumbach}}</ref>. It is there that Kao did his first groundbreaking work as an engineer and researcher.

Kao joined the [[Chinese University of Hong Kong]] (CUHK) in 1970, to found the Department of Electronics, which later became the [http://www.ee.cuhk.edu.hk/ Department of Electronic Engineering]. During this period, Kao was the [[Reader (academic rank)|Reader]] and then the [[Chair (academic)|Chair]] Professor of Electronics at CUHK; he built up both [[Undergraduate education|undergraduate]] and [[Postgraduate education|graduate]] study programs of electronic and saw the first graduation of his students. Under his leadership, the School of Education and other new research institutes were established. He then went back to [[ITT Corporation]] in 1974 (the parent corporation of STC at that time), and the United States, and worked in [[Roanoke, Virginia]], first as Chief Scientist and later as Director of Engineering. In 1982, he became the first ITT Executive Scientist and was stationed mainly at the Advanced Technology Center in [[Connecticut]].<ref name=networkchinese/> While there, he served as an adjunct professor and Fellow of Trumbull College at [[Yale University]]. In 1985, Kao spent one year in [[West Germany]], at SEL Research Center. In 1986, Kao was the Corporate Director of Research at ITT.

Kao was Vice-Chancellor (equivalent to President in universities of the United States) of the [[Chinese University of Hong Kong]] from 1987 to 1996<ref>[http://www.cuhk.edu.hk/adm/handbook/history.pdf CUHK Handbook]</ref>. From 1993 to 1994, he was the President of ASAIHL (The Association of Southeast Asian Institutions of Higher Learning)<ref>{{cite web|url=http://www.seameo.org/asaihl/ |title=President of ASAIHL |publisher=ASAIHL |date= |accessdate=2009-11-01}}</ref>.

Kao then worked as the CEO of Transtech. He is currently Chairman and CEO of ITX Services. As of 2009, he resides in Hong Kong and often travels to the United States to visit his family.

In 2000, Kao founded the [[Independent Schools Foundation Academy]] (ISF), which is located in [[Cyberport]], Hong Kong.<ref>http://www.isf.edu.hk/eng/news.php?id=22</ref> He stepped down from the Board of the ISF Foundation in December, 2008.

Kao has been suffering slightly from [[Alzheimer's disease]] since early 2004 and has [[Speech disorder|speech difficulty]], but has no problem recognizing people or addresses.<ref>Ifeng.com: [http://news.ifeng.com/world/200910/1006_16_1377679.shtml 港媒年初传高锟患老年痴呆症 妻称老人家记性差]</ref> Kao's father also suffered from the same disease. Kao and his wife would like to donate part of the prize money to [[aging]] research and care, possibly to the Hong Kong St. James' Settlement Health Care Centre for Old People, and the American-based [[Alzheimer's Association]].<ref>ScienceNet: [http://www.sciencenet.cn/htmlnews/2009/10/223917.shtm 华裔诺奖获得者高锟将捐赠部分奖金研究老人病]</ref>

[[Chinese ceramics|Pottery]] making, a traditional Chinese handwork, is a hobby of Kao's. Kao also enjoys reading [[Wuxia]] [[novel]]s.<ref>[[QQ]].com News [http://news.qq.com/a/20091008/000798.htm 记者探访“光纤之父”高锟:顽皮慈爱的笑]</ref>

On October 6, 2009, Kao was awarded the Nobel Prize in Physics for his contributions to the study of the transmission of light in optical fibers and for fiber communication<ref>{{cite web|url=http://nobelprize.org/nobel_prizes/physics/laureates/2009/ |title=Physics 2009 |publisher=Nobelprize.org |date= |accessdate=2009-10-26}}</ref>, said: "''I am absolutely speechless and never expected such an honour''"<ref>{{cite web|url=http://www.guardian.co.uk/science/2009/oct/06/nobel-prize-physics-charles-kao |title=Charles Kuen Kao, George Smith and Willard Boyle win Nobel for physics |publisher=[[The Guardian|guardian.co.uk]] |date= Tuesday 6 October 2009 21.18 BST |author= Ian Sample, science correspondent |accessdate=2009-11-30}}</ref>.

===Ancestry and family===
Kao's father Kao Chun-Hsiang ([[:zh:高君湘|高君湘]]) was a lawyer, who obtained his [[Juris Doctor|J.D.]] from the [[University of Michigan Law School]] in 1925.<ref>University of Michigan Law School: [http://www.law.umich.edu/historyandtraditions/students/GraduateListPDFS/K.pdf Alphabetical List with Year of Law School Graduates]</ref> He was a professor at [[Soochow University (Suzhou)|Soochow University]] (then in Shanghai) Comparative Law School of China.<ref>[http://www.yadian.cc/corpus/1211/ A short biography of Kao Hieh-Hsiang]</ref><ref>[http://journal.chinalawinfo.com/Article_Info.asp?Id=125689 Legal education in modern China and modern Chinese jurisprudence]</ref>

His grandfather was Kao Choi-Wan (Gao Chuiwan, [[:zh:高吹萬|高吹萬]]), a famous poet, revolutionary, literator, and a leading figure of ''Nan Society'' (''South Society'', [[:zh:南社|南社]]) during the late [[Qing Dynasty]].<ref>{{cite web|url=http://nanshewan.b121.53dns.com/suzhi/jnhxsl.txt|title=参加南社纪念会姓氏录 List of Nan Society member|publisher=南社研究網 Research of Nan Society|accessdate=2009-10-08|language={{zh icon}}}}</ref>

[[Image:Fibreoptic.jpg|thumb|right|200px|upright|A bundle of [[silica glass]] fibers for optical communication, which are used everywhere nowadays. Kao also first suggested that silica glass was ideal material for long range optical communication. See also ''[[strength of glass]]''.]]

In early 1960s at STL, Kao did his pioneering work in the realisation of [[fiber optics]] as a telecommunications medium, by demonstrating that the high-loss of existing fiber optics arose from impurities in the glass, rather than from an underlying problem with the technology itself<ref>{{cite web|url= |title=''Fiber optic data communication: technological trends and advances'' (Editor: Casimer DeCusatis, ISBN 0-12-207891-8): Chapter 1 - History of Fiber Optics (by Jeff D. Montgomary); 1.3.1. Long Road to Low-Loss Fiber (Page 9-16)|format= Book chapter|date=Academic Press; 1<sup>st</sup> Edition (March 22, 2002) |accessdate=2009-11-02}}</ref>. Kao was pointed to the head of the electro-optics research group at STL in 1963<ref name="IET" >{{cite web|url=http://kn.theiet.org/news/oct09/comms-nobel.cfm |title=Communication pioneers win 2009 physics Nobel |format= |publisher=[[Institution of Engineering and Technology|IET]] |date=Published on 7 October 2009 |accessdate=2009-10-28}}</ref>; he took over the whole optical communication program of STL in December 1964 and decided to overall change their research direction. Kao not only considered the optical physics but also the material properties. The results were first presented by Kao in January 1966 in London, and further published in July with his former colleague [[George Hockham]] (1964-1965)<ref>{{cite journal |first1=K. C. |last1=Kao |first2=G. A. |last2=Hockham |year=1966|title=Dielectric-fibre surface waveguides for optical frequencies |journal=Proc. IEE |volume=113 |issue=7 |pages=1151–1158}}</ref>{{Cref|a}}. This study first theorized and proposed to use glass fibers to implement optical communication, the ideas (especially structural features and materials) described largely are the basis of today's optical fiber communication.

In 1965<ref name="IET" /><ref>{{cite web|url= |title=''Microstructured Polymer Optical Fibres'', by Maryanne C. J. Large, Leon Poladian,Geoff Barton, and Martijn A. van Eijkelenborg. ISBN 9780387312736 |format= |publisher=[[Springer Science+Business Media|Springer]] |date=2008 |accessdate=2009-11-04}} Page '''2'''</ref>{{Cref|b}}, Kao concluded that the fundamental limitation for glass light [[attenuation]] is below 20 ''dB/km'' (''[[Decibels]] per [[Kilometer]]'', is a measure of the attenuation of a signal over a distance), which is a key threshold value for optical communications (<ref name="Fiber Types" >{{cite web|url=http://www.cisco.com/en/US/prod/collateral/modules/ps5455/white_paper_c11-463661.pdf |title=Fiber Types in Gigabit Optical Communications |format=PDF |publisher=[[Cisco Systems]], USA |date=April 2008 |accessdate=2009-11-03}}</ref>it was first reported by Kao to [[Institution of Electrical Engineers|IEE]] in London in January 1966)<ref>{{cite web|url=http://ujdigispace.uj.ac.za:8080/dspace/bitstream/10210/2173/7/Chapter1FINAL.pdf |title=Chapter 1.1 - The Evolution of Fibre Optics |format=PDF |date= |accessdate=2009-10-28}}</ref>. However, at the time of this determination, optical fibers commonly exhibited light loss as high as 1,000 db/km and even more. This conclusion opened the intense race to find low-loss materials and suitable fibers for reaching such criteria.

Kao, together with his new team (members including T.W. Davies, M.W. Jones, and C.R. Wright), pursued this goal by testing various materials. They precisely measured the attenuation of light with different wavelengths in glasses and other materials. During this period, Kao pointed out that the high purity of fused silica (SiO<sub>2</sub>) made it an ideal candidate for optical communication. Kao also stated that the impurity of glass material is the main cause for the dramatic decay of light transmission inside glass fiber, rather than fundamental physical effects such as [[scattering]] as many physicists thought at that time, and such impurity could be removed. This led to a worldwide study and production of high-purity glass fibers.<ref name="phyadv09">{{cite web|url=http://nobelprize.org/nobel_prizes/physics/laureates/2009/phyadv09.pdf |title=2009 Nobel Prize in Physics - Scientific Background: Two revolutionary optical technologies - Optical fiber with high transmission|format=PDF |publisher=Nobelprize.org |date= 2009-10-06|accessdate=2009-12-04}}</ref> Theatrically, when Kao first proposed that such glass fiber could be used for long-distance information transfer and replace [[copper wire]]s which were used for [[telecommunication]] during that era<ref>[http://www8.nationalacademies.org/onpinews/newsitem.aspx?RecordID=02222000 1999 Charles Stark Draper Award Presented] "'''''Kao''', who was working at ITT's Standard Telecommunications Laboratories in the 1960s, theorized about how to use light for communication instead of bulky copper wire and was the '''first''' to publicly propose the possibility of a practical application for fiber-optic telecommunication.''"</ref>, his ideas were widely disbelieved; later people realized that Kao's ideas revolutionized the whole communication technology and industry.

In 1968, Kao with M.W. Jones measured the intrinsic loss of bulk-fused silica at 4 dB/km, which is the first evidence of ultra-transparent glass. [[Bell Laboratories]] started considering fiber optics seriously.<ref name="A Fiber-Optic Chronology" >{{cite web|url=http://www.sff.net/people/Jeff.Hecht/chron.html |title=A Fiber-Optic Chronology (by Jeff Hecht) |accessdate=2009-11-03 }}</ref>

Kao developed important techniques and configurations for glass fiber waveguides, and contributed to the development of different fiber types and system devices which met both civil and [[Military communications|military]]{{Cref|*}} application requirements, and peripheral supporting systems for optical fiber communication<ref name="Charles Kuen Kao">{{cite web|url=http://cradle.wykontario.org/wp-content/uploads/Dr_Kao.pdf |title=Charles Kuen Kao |format=PDF |date= |accessdate=2009-10-28}}</ref>. In mid-1970s, he did seminal work on glass fiber [[Fatigue limit|fatigue strength]]<ref name="Charles Kuen Kao" />. Kao also played a major role in the engineering and commercial realisation of optical communication<ref name="Charles Kuen Kao" />. He visited many research institutes including Bell Labs and even glass factories, discussed with various people including engineers, scientists, businessmen about the techniques and improvement of glass fiber manufacture. When named the first ITT Executive Scientist, Kao launched the "[[Terabit]] Technology" program in addressing the high frequency limits of signal processing, so Kao is also known as the "''Father of Terabit Technology Concept''"<ref name="Charles Kuen Kao" /><ref>''Technology of Our Times: People and Innovation in Optics and Optoelectronics'' (SPIE Press Monograph Vol. PM04), by Frederick Su; [[SPIE]] Publications (July 1, 1990); ISBN 0819404721, ISBN 978-0819404725. Page '''82-86''', Terabit Technology, by Charles K. Kao.</ref>. Kao has published more than 100 papers and was granted over 30 [[patent]]s<ref name="Charles Kuen Kao" />, including the water-resistant high-strength fibers (with M.S. Maklad)<ref>{{cite web|url=http://www.freepatentsonline.com/4183621.html |title=Water resistant high strength fibers (United States Patent 4183621) |format=PDF |date= Filing Date: 12/29/1977; Publication Date: 01/15/1980 |accessdate=2009-11-01}}</ref>.

At early stage of developing optic fibers, Kao already strongly preferred [[Single-mode optical fiber|single mode]] for long-distance optical communication, instead of using [[Multi-mode optical fiber|multi-mode system]]s. His vision later was followed and now applied almost exclusively.<ref>{{cite web|url=http://kn.theiet.org/news/oct09/guiding-light.cfm |title=Guiding light |format=PDF |date= IEE REVIEW MAY 1989 |accessdate=2009-12-04}}</ref><ref name="phyadv09" />

Kao is also a pioneer of modern [[submarine communications cable]]s and largely promoted this idea. He predicted in 1983 that world's seas would be littered with fiber optics, five years ahead such trans-oceanic fiber-optic cable first became serviceable.<ref>{{cite web|url=http://www.springerlink.com/content/um81r1t511321752/fulltext.pdf?page=1 |title=''Building the Global Fiber Optics Superhighway'' (ISBN 978-0-306-46505-5 (Print) 978-0-306-46979-4 (Online)): 1, A Global Footprint |format=PDF (Free Abstract)|date= May 8, 2007 |publisher=[[Springer Science+Business Media|Springer]] USA |accessdate=2009-11-03}}</ref>

[[Ali Javan]]’s introduction of steady [[helium-neon laser]] and Kao’s discovery of fiber light-loss properties now are recognized as two essential milestones for the development of fiber-optic communications.<ref name="Fiber Types" />

Charles Kuen ("K. C.") Kao CBE FRS[2] FREng[3] (traditional Chinese: 高錕; simplified Chinese: 高锟; pinyin: Gāo Kūn (Kao Kuen); born 4 November 1933) is a pioneer in the development and use of fiber optics in telecommunications. Kao, widely regarded as the "Father of Fiber Optics" or "Father of Fiber Optic Communications",[4][5][6][7][8] was awarded half of the 2009 Nobel Prize in Physics for "groundbreaking achievements concerning the transmission of light in fibers for optical communication".[9]

Biography

Kao was born in Shanghai in 1933, but his ancestral home is in Jinshan, Jiangsu now part of Shanghai. He studied Chinese classics at home with his brother, under a tutor.[10] He also studied English and French at an international school in Shanghai which was founded by a number of progressive Chinese educators including Cài Yuánpéi (蔡元培).[11]

Kao's family moved to Hong Kong in 1948[12] where he completed his secondary education (advanced level) at St. Joseph's College in 1952. He did his undergraduate studies in electrical engineering at Woolwich Polytechnic (now the University of Greenwich),[13] obtaining his Bachelor of Science degree issued by the University of London.

He then pursued research and received his PhD degree in electrical engineering in 1965 from University College London[14] (under Professor Harold Barlow) as an external student while working at Standard Telecommunication Laboratories (STL) in Harlow, England, the research centre of Standard Telephones and Cables[15]. It is there that Kao did his first groundbreaking work as an engineer and researcher.

Kao joined the Chinese University of Hong Kong (CUHK) in 1970, to found the Department of Electronics, which later became the Department of Electronic Engineering. During this period, Kao was the Reader and then the Chair Professor of Electronics at CUHK; he built up both undergraduate and graduate study programs of electronic and saw the first graduation of his students. Under his leadership, the School of Education and other new research institutes were established. He then went back to ITT Corporation in 1974 (the parent corporation of STC at that time), and the United States, and worked in Roanoke, Virginia, first as Chief Scientist and later as Director of Engineering. In 1982, he became the first ITT Executive Scientist and was stationed mainly at the Advanced Technology Center in Connecticut.[6] While there, he served as an adjunct professor and Fellow of Trumbull College at Yale University. In 1985, Kao spent one year in West Germany, at SEL Research Center. In 1986, Kao was the Corporate Director of Research at ITT.

Kao was Vice-Chancellor (equivalent to President in universities of the United States) of the Chinese University of Hong Kong from 1987 to 1996[16]. From 1993 to 1994, he was the President of ASAIHL (The Association of Southeast Asian Institutions of Higher Learning)[17].

Kao then worked as the CEO of Transtech. He is currently Chairman and CEO of ITX Services. As of 2009, he resides in Hong Kong and often travels to the United States to visit his family.

In 2000, Kao founded the Independent Schools Foundation Academy (ISF), which is located in Cyberport, Hong Kong.[18] He stepped down from the Board of the ISF Foundation in December, 2008.

Kao has been suffering slightly from Alzheimer's disease since early 2004 and has speech difficulty, but has no problem recognizing people or addresses.[19] Kao's father also suffered from the same disease. Kao and his wife would like to donate part of the prize money to aging research and care, possibly to the Hong Kong St. James' Settlement Health Care Centre for Old People, and the American-based Alzheimer's Association.[20]

Pottery making, a traditional Chinese handwork, is a hobby of Kao's. Kao also enjoys reading Wuxia novels.[21]

On October 6, 2009, Kao was awarded the Nobel Prize in Physics for his contributions to the study of the transmission of light in optical fibers and for fiber communication[22], said: "I am absolutely speechless and never expected such an honour"[23].

Ancestry and family

Kao's father Kao Chun-Hsiang (高君湘) was a lawyer, who obtained his J.D. from the University of Michigan Law School in 1925.[24] He was a professor at Soochow University (then in Shanghai) Comparative Law School of China.[25][26]

His grandfather was Kao Choi-Wan (Gao Chuiwan, 高吹萬), a famous poet, revolutionary, literator, and a leading figure of Nan Society (South Society, 南社) during the late Qing Dynasty.[27]

His father's cousin was astronomer Ping-Tse Kao (高平子;[28] Kao Crater is named after him[29]) Kao has a younger brother named Timothy Wu Kao (高鋙), who is a civil engineer and Professor Emeritus at the Catholic University of America in Washington, D.C.. His research is in hydrodynamics.[30]

Kao met his future wife May-Wan Kao (Née: Wong; 黄美芸) in London after graduation. His wife was a Fortran programmer working in the same factory as Kao.[31] She is British Chinese. They were married in 1959 in London, [32][33] and have two children, a son and a younger daughter,[32] both of whom reside and work in Silicon Valley, California.[31]

A bundle of silica glass fibers for optical communication, which are used everywhere nowadays. Kao also first suggested that silica glass was ideal material for long range optical communication. See also strength of glass.

In early 1960s at STL, Kao did his pioneering work in the realisation of fiber optics as a telecommunications medium, by demonstrating that the high-loss of existing fiber optics arose from impurities in the glass, rather than from an underlying problem with the technology itself[34]. Kao was pointed to the head of the electro-optics research group at STL in 1963[35]; he took over the whole optical communication program of STL in December 1964 and decided to overall change their research direction. Kao not only considered the optical physics but also the material properties. The results were first presented by Kao in January 1966 in London, and further published in July with his former colleague George Hockham (1964-1965)[36][a]. This study first theorized and proposed to use glass fibers to implement optical communication, the ideas (especially structural features and materials) described largely are the basis of today's optical fiber communication.

In 1965[35][37][b], Kao concluded that the fundamental limitation for glass light attenuation is below 20 dB/km (Decibels per Kilometer, is a measure of the attenuation of a signal over a distance), which is a key threshold value for optical communications ([38]it was first reported by Kao to IEE in London in January 1966)[39]. However, at the time of this determination, optical fibers commonly exhibited light loss as high as 1,000 db/km and even more. This conclusion opened the intense race to find low-loss materials and suitable fibers for reaching such criteria.

Kao, together with his new team (members including T.W. Davies, M.W. Jones, and C.R. Wright), pursued this goal by testing various materials. They precisely measured the attenuation of light with different wavelengths in glasses and other materials. During this period, Kao pointed out that the high purity of fused silica (SiO2) made it an ideal candidate for optical communication. Kao also stated that the impurity of glass material is the main cause for the dramatic decay of light transmission inside glass fiber, rather than fundamental physical effects such as scattering as many physicists thought at that time, and such impurity could be removed. This led to a worldwide study and production of high-purity glass fibers.[40] Theatrically, when Kao first proposed that such glass fiber could be used for long-distance information transfer and replace copper wires which were used for telecommunication during that era[41], his ideas were widely disbelieved; later people realized that Kao's ideas revolutionized the whole communication technology and industry.

In 1968, Kao with M.W. Jones measured the intrinsic loss of bulk-fused silica at 4 dB/km, which is the first evidence of ultra-transparent glass. Bell Laboratories started considering fiber optics seriously.[42]

Kao developed important techniques and configurations for glass fiber waveguides, and contributed to the development of different fiber types and system devices which met both civil and military[*] application requirements, and peripheral supporting systems for optical fiber communication[43]. In mid-1970s, he did seminal work on glass fiber fatigue strength[43]. Kao also played a major role in the engineering and commercial realisation of optical communication[43]. He visited many research institutes including Bell Labs and even glass factories, discussed with various people including engineers, scientists, businessmen about the techniques and improvement of glass fiber manufacture. When named the first ITT Executive Scientist, Kao launched the "Terabit Technology" program in addressing the high frequency limits of signal processing, so Kao is also known as the "Father of Terabit Technology Concept"[43][44]. Kao has published more than 100 papers and was granted over 30 patents[43], including the water-resistant high-strength fibers (with M.S. Maklad)[45].

At early stage of developing optic fibers, Kao already strongly preferred single mode for long-distance optical communication, instead of using multi-mode systems. His vision later was followed and now applied almost exclusively.[46][40]

Kao is also a pioneer of modern submarine communications cables and largely promoted this idea. He predicted in 1983 that world's seas would be littered with fiber optics, five years ahead such trans-oceanic fiber-optic cable first became serviceable.[47]

Ali Javan’s introduction of steady helium-neon laser and Kao’s discovery of fiber light-loss properties now are recognized as two essential milestones for the development of fiber-optic communications.[38]
