Tyco Submarine Systems (TSSL) and Cisco Systems yesterday announced the first demonstration of IP packet transport over a trans-oceanic non-regenerated dense wavelength division multiplexing (DWDM) system.
Completed without the need for time-division multiplexing (TDM), the transmission was deployed by connecting Cisco 12000Gbit switch routers with interface cards directly to TSSL's 7500-kilometre trans-oceanic DWDM testbed using only optical amplifiers.
According to officials, the demonstration marked the latest development in undersea network communications.
"The same compelling performance and economic advantages that have been proven in terrestrial IP backbones can now be applied to the trans-oceanic space," Graeme Fraser, vice president and general manager of the optical Internet working business unit at Cisco System said. "We demonstrated that it is possible to build a global IP network in which the entire system operates at 2.5Gbit/sec."
TSSL operates a fleet of cable ships for the installation and maintenance of undersea communications network systems.
