Two more interesting submarine cable news items yesterday from the Pacific. Alcatel-Lucent (NYSE:ALU, news, filings) said that it has upgraded an unnamed but easily identified cable system linking Japan and California, while Infinera (NASDAQ:INFN, news, filings) has demoed 100G with SD-FEC.
Alcatel-Lucent announced that it has implemented its 40G coherent technology (extendable to 100G naturally) to add 1Tbps to the cable’s current capacity, bringing it up to 4Tbps. They didn’t say which cable, but a quick search turns up only one cable system that matches the parameters given: 9,600km of subsea fiber landing in Japan and California and owned jointly by five companies. It must be the Unity cable, which debuted in the Spring of 2010 and is owned by Google, Global Transit, SingTel, KDDI, and Bharti Airtel. Pacnet owns two fiber pairs on the system, but operates them independently as EAC Pacific.
Meanwhile, Infinera (NASDAQ:INFN, news, filings) was also putting its latest gear to work in the Pacific. Yesterday they teamed up with Australia’s Telstra Global in a demonstration of 100G with Soft Decision Forward Error Correction (SD-FEC) via its DTN-X platform. The trial was done on the 4,200km span of the Asia America Gateway between San Luis Obispo and Oahu in Hawaii, where not coincidentally PTC is going on right now. Infinera says its SD-FEC capabilities have the capability to double the transmission capacity of existing cables.
