TGN-Pacific (TGN-P[1], previously VSNL Transpacific) is a submarine telecommunications cable system transiting the Pacific ocean.

The cable system is constructed with one cable from Emi, Japan, to Hillsboro, Oregon, United States; one from Toyohashi, Japan, to Hillsboro; one from Toyohashi, Japan, to Los Angeles, California, United States; and one from Toyohashi to Guam. The TGN-P "Southern" route between Guam, Hawaii, and California was built but one fiber of the 8 was damaged over the Marianas Trench and the southern system was transferred to the US Department of Justice when TYCOM TGN was sold to VSNL in bankruptcy. The cables between Japan and Hillsboro are each constructed with 8 fibre pairs per cable. At construction the cable could support up to 96 10 Gbit/s waves in its 2001 configuration. In 2014 the cable was upgraded to 100G optical transport.[2]

It has landing points in:

Tata Communications (formerly VSNL[3]) acquired the cable from its builder Tyco in May, 2005[4].
