[edit] Performance
Total bandwidth capacity of Asia Pacific Cable Network 2 is 2.56 Tbit/s, made up of four pairs of optical fibres, each pair providing 640 Gbit/s by Dense Wavelength Division Multiplexing of 10 Gbit/s wavelengths. The 19,000 km-long APCN 2 cable system is built in a self-healing ring configuration, which allows fast rerouting of data transfers along APCN 2 in the event of disruptions. The cable system, as of January 2007, is progressively becoming operational. APCN 2 is designed to provide interconnection with other major trans-oceanic cable networks linking the USA, Europe, Australia, and other parts of Asia.
