ABS facilitated a Polar Code Operational Assessment, a milestone in the implementation of the IMO Polar Code. The assessment, which identifies operational risks and limitations, was performed with TE SubCom, a TE Connectivity Ltd. company and an industry pioneer in undersea communications technology, on its cable-laying vessel, Responder. “Completing this assessment is a critical milestone for the marine industry and the first of its kind in North America,” says ABS Chairman, President and CEO Christopher J. Wiernicki. To obtain a Polar Ship Certification (PSC), vessels undergo an assessment that defines the intended operational profile and identifies relevant hazards.

TE SubCom has announced the commencement of the new Hibernia Express submarine cable system. The 4,600 km cable will provide the lowest-latency fiber-optic path between New York and London, connecting Halifax, Nova Scotia and Brean, UK, with terrestrial fiber to extend connectivity to the major metro areas. Hibernia Express will initially launch with 100 Gbps transmission capacity using TE SubCom’s C100 SLTE platform. It will be a 6-fiber-pair submarine cable, with a portion of the fibers optimized for lowest latency and a portion optimized for 100x100 Gbps design capacity. The total cross-sectional design capacity of the cable will be over 53 Tbps.

TE SubCom, a TE Connectivity Ltd. company, announced that its engineers have demonstrated record-breaking transpacific transmission using both 200Gb/s and 400Gb/s data channels. The results, presented at the recent post deadline session of the 2013 OFC/NFOEC conference in Anaheim, CA, demonstrated a total capacity on a single fiber pair of 21Tb/s transmitted over more than 10,000km at a spectral efficiency of 6b/s/Hz. This achievement was enabled by careful engineering of the transmitted signals, in order to achieve both long-distance performance and high spectral utilization. “Transpacific length transmission at 6b/s/Hz spectral efficiency is a significant milestone for undersea communications,” said Seymour Shapiro, CTO, TE SubCom.

TE SubCom contracted by Chevron to connect the Jack & St. Malo offshore facility with an undersea fiber optic communications system in the deepwater U.S. Gulf of Mexico. Jack & St. Malo fields are located approximately 280 miles south of New Orleans, LA in water depths of 7,000 feet. The fields are supported by a semi-submersible platform which will be connected by 106km of submarine cable, subsea equipment, and a new branching unit to an existing fiber network. The branching unit will incorporate SubCom’s proprietary OADM technology and transmission requirements will be met by SubCom’s leading submarine line terminating equipment installed on the facility and in landing stations located in Mississippi and Texas.

Company Demonstrates 100Gb/s-Based Transmission at 10Tb/s per Fiber Pair with First Generation Coherent Transmission Equipment. TE SubCom, a TE Connectivity Ltd. Company and an industry pioneer in undersea communications technology, today announced it has successfully demonstrated 100Gb/s coherent transmission over trans-Atlantic distances at ultra-high 10Tb/s total capacity on a single fiber. The test was completed using a prototype of the company’s new, first generation smarTEr C100 transceiver. “This significant customer demonstration builds on a 60-year track record of commitment to specialized, long-haul undersea transmission research and development and success in delivering capacity-record-setting undersea cable systems,” said David Coughlan, CEO, TE SubCom.

MORRISTOWN, NJ, USA – May 2, 2011 –TE SubCom (SubCom), an industry pioneer in undersea communications technology, today announced it has successfully completed testing of its new 4-port branching unit, making it the first undersea communications supplier to offer the solution and paving the way for the deployment of multilayered undersea telecommunication networks. An upgrade from the standard 3-port branching unit (BU), the 4-port BU is capable of handling three separate power paths and enables alternative powering configurations.

According to allafrica.com, the construction of the 42650 ft. Sea Cable System connecting the South and East Africa countries of South Africa, Mozambique, Madagascar, Kenya and Tanzania with India and Egypt has commenced. SEACOM Limited and its supplier -Tyco telecommunications, a business segment of Tyco Electronics Limited and an industry pioneer in undersea communications technology and marine services are carrying the project. SEACOM attained full and unconditional financial close on November 9, 2007. SEACOM and Tyco Telecommunications brought the construction contract for the full delivery of the system in force on November 13, 2007.
