SEA-US Cable to south-east Asia now being laid from California

17 January 2017 | Alan Burkitt-Gray


A new $250 million subsea cable system linking mainland US with Hawaii and south-east Asia has won a US licence and has started the main phase of construction.

The Southeast Asia-US (SEA-US) Cable System has already been landed in California and next month the installation vessel will arrive in Honolulu after completing its main-lay construction between California and Hawaii.

When completed, the system will deliver an initial design capacity of 20Tbps using 100Gpbs technology from NEC, which is building the cable for a consortium of seven members, including Globe Telecom of the Philippines and Telin of Indonesia.

Completion date is set for the second quarter of 2017 – about six months behind the schedule that was announced when the project began in August 2014.

The Federal Communications Commission (FCC) gave SEA-US a licence on 12 January and the cable is due to be connected to CoreSite’s LA2 data centre in Los Angeles by the end of the month. The Hermosa Beach landing station is connected to the data centre over physically diverse dark fibre pairs, said Globe Telecom.

As well as Globe and Telin, investors in SEA-US are GTA of Guam, GTI of California, Hawaiian Telcom, RTI of California and Telin’s Telkom USA of California.

The 15,000km cable is designed to connect California and Hawaii with Manado in Indonesia, Davao in southern Philippines and Piti in the US territory of Guam.
