TE SubCom, a TE Connectivity Ltd. company and an industry pioneer in undersea communications technology, has announced it has successfully demonstrated 100Gb/s per wavelength coherent transmission over trans-Atlantic distances in field experiments.
Capacity on a single fiber was determined to reach 4.4 Tb/s, a result of SubCom’s submarine optimized modulation format at 100Gb/s. SubCom’s next generation C100 transceiver is designed to optimize DP-QPSK coherent transmission in ultra-long haul submarine cable systems. The benefits of the C100 technology apply to new systems based on +D fibers, as well as upgrades to existing systems with dispersion managed fiber.
“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 11,000km, and utilizing the latest +D fibers.”
Leading the industry with a number of ultra-long haul distance solutions, TE SubCom has long embraced the movement toward 100G. It has developed a very unique product with ultra-long reach up to 11,000km and capabilities of up to 15 TB/s demonstrated on beta hardware prototypes. Particularly well-suited for new builds, a number of SubCom customers have already begun to take advantage of this capability by building future-proofed systems at 100G.
