Infinera grows 100G subsea network to 38,000km

Infinera Corp of Sunnyvale, CA, USA, a vertically integrated manufacturer of digital optical network systems incorporating its own indium phosphide-based photonic integrated circuits (PICs), says that its DTN-X platform with ultra-long haul 500G FlexCoherent super-channel technology is now being deployed in eight subsea networks across approximately 38,000 route kilometers of undersea fiber. Infinera has publicly announced the DTN-X platform in submarine networks with customers including Telefonica, MedNautilus, PIPE Networks, PACNET and KDDI.

Infinera says that its network solutions have reduced deployment times from months to days while improving space utilization by up to 33%.

“There is a significant opportunity for 100G coherent solutions in the long haul subsea market," said Ron Kline, principal analyst Network Infrastructure, Ovum. “100G upgrades for subsea systems are definitely becoming more common, particularly as the financing climate for new cables remains weak and operators can increase capacity by a factor of ten in a short time period compared to constructing a new cable system.”

“Subsea network operators are very discerning customers because they operate mission-critical networks that typically exceed terrestrial specifications,” said Steve Grubb, Infinera Fellow. "With demand for increased capacity on Submarine routes, the DTN-X, featuring FlexCoherent technology, is delivering submarine operators differentiation in the form of speed and reliability as well as lower total cost of ownership for 100G coherent optical subsea networks.  Further, with network resiliency enhancements like Infinera’s FastSMP, network protection not only improves reliability, but also lowers cost."

Earlier this year, Infinera conducted a trial with Telstra Global, successfully demonstrating Soft Decision Forward Error Correction (SD-FEC) across a 4,200 km submarine link between Hawaii and California.

Infinera will participate at the SubOptic 2013 Conference which takes place 22-25 April at the Marriott Rive Gauche, Paris, France. At the conference, Infinera engineers will discuss the latest optical networking technologies to support submarine networks and share how the innovation behind the Infinera DTN-X platform has enabled Infinera to gain traction in submarine networks globally.

Infinera's engineers will give presentations addressing the latest developments in technologies that enable next-generation submarine networking solutions:
