Infinera sends data over record 4,000 km optical subsea network

March 24, 2009--Infinera (Sunnyvale, CA) successfully concluded a demonstration in which its photonic integrated circuit (PIC)-based optical communications network architecture (called DTN) transmitted data over a 4,000 km third-party subsea network. Using a 25 GHz channel spacing (compared to 50 GHz on pre-existing equipment, the Infinera system doubled the bandwidth capacity of the sub-sea network.

March 24, 2009--Infinera (Sunnyvale, CA) successfully concluded a demonstration in which its photonic integrated circuit (PIC)-based optical communications network architecture (called DTN) transmitted data over a 4,000 km third-party subsea network. Using a 25 GHz channel spacing (compared to 50 GHz on pre-existing equipment, the Infinera system doubled the bandwidth capacity of the sub-sea network.

This demonstration and other attributes of Infinera's DTN system will be discussed today by Infinera Fellow Steve Grubb at the OFC/NFOEC conference in San Diego in a Market Watch session entitled "More Wavelengths, Higher Bit Rates, More Spectrum … The Path to Harnessing Maximum Fiber Capacity at the Lowest Cost."

"The ability of the Infinera DTN to transmit data undersea for 4,000 kilometers, and over a foreign amplifier chain is a pathbreaking demonstration, which holds out the opportunity of a new, innovative, and cost-effective way to increase capacity on subsea networks," said Grubb. Submarine optical networks include chains of subsea optical amplifiers, designed for the demands of operation on the ocean floor, and submarine line terminating equipment (SLTE) located in terrestrial landing stations and connected to either end of the amplifier chain. In this demonstration, Infinera DTNs replaced the pre-existing SLTE systems and transmitted dense wavelength-division multiplexing (DWDM) optical signals across the pre-existing subsea amplifier chain.
