TE Subcom demos coherent 100G on transatlantic submarine cable system

Undersea fiber-optic cable systems equipment developer TE SubCom, a TE Connectivity Ltd. Company, says it has successfully demonstrated the capabilities of its 100-Gbps C100 transmitter. The demonstration saw the successful transmission of 100G coherent transmission on a transatlantic undersea fiber-optic network constructed in 2001.

Undersea fiber-optic cable systems equipment developer TE SubCom, a TE Connectivity Ltd. Company, says it has successfully demonstrated the capabilities of its 100-Gbps C100 transmitter. The demonstration saw the successful transmission of 100G coherent transmission on a transatlantic undersea fiber-optic network constructed in 2001.

The C100 leverages dual-polarization quadrature phase-shift keying (DP-QPSK) with coherent detection. During the demonstration, use of the transmitter technology was shown to support 4.4 Tbps on a single fiber. The C100 can be effective on both new systems based on +D fibers as well as system upgrades on networks with dispersion managed fiber, TE Subcom says.

“Emerging high-bandwidth applications such as video and cloud computing continue to increase the demand on today’s networks,” said Seymour Shapiro, CTO, TE SubCom. “Carriers must take advantage of technology enhancements to deliver the most cost-effective solutions to this tremendous challenge. SubCom’s latest C100 coherent solutions increase network capacity on both today’s existing undersea cables and tomorrow’s new cables, with reaches up to 11,000 km, and utilizing the latest +D fibers.”

TE SubCom asserts it has demonstrated the ability to support reaches up to 11,000 km with capabilities of up to 15 Tbps on beta hardware prototypes. It adds that a number of its customers have already begun to leverage the 100G technology in their networks.
