New Technology Enables Multilayered Subsea Telecommunications Networks
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. In testing, SubCom integrated two 4-port BUs with a variety of armored and unarmored cables as part of separate systems. The company completed two comprehensive sea trials in shallow water and deep water and confirmed the successful deployment, sea-bed placement and recovery of the 4-port BUs using standard shipboard equipment.

“Our 4-port BU  utilizes the same SubCom branching unit body and branch coupling assembly as the 3-port BU, meaning this new technology offers the same high performance and reliability our customers have come to expect,” said Maurice Kordahi, Managing Director Wet Plant Development at SubCom.

Adding to SubCom’s unique and flexible offerings, the 4-port BU provides the enhanced ability to develop customized solutions for a wide range of uses and customers. SubCom plans to use the product in new installations, upgrades and extensions to existing systems. 

“We view this development as a significant step in meeting the evolving needs of the subsea cable industry, as well as the oil, gas and scientific research markets,” said Derek Buffitt, Director, Special Projects at SubCom. “We’re pleased to not only offer our customers an unprecedented piece of state-of-the-art equipment, but also the ability to use a single undersea infrastructure for distinct data transmission layers.”
