Facebook, Google among Builders of New Transpacific Cable

Undersea communications technology company TE SubCom has partnered up with Facebook, Google and Pacific Light Data Communication Co. Ltd. (PLDC) to co-build a 12,800 km transpacific submarine cable system that will provide the first direct undersea route between Hong Kong and Los Angeles with ultra-high capacity transmission. Scheduled for commercial launch in summer of 2018, the Pacific Light Cable Network (PLCN) will become the highest-capacity transpacific route when completed largely thanks to TE SubCom's C+L technology, which effectively doubles the available bandwidth and capacity per fiber
