   DALLAS--(Business Wire)--Xtera Communications, Inc. ("Xtera"), a leading global provider of opticalnetworking solutions, announced today the availability of 100G technology forlong-haul subsea cable systems. Xtera is the first supplier to have installed100G Submarine Line Terminal Equipment (SLTE) on a repeatered subsea cablesystem: this project was awarded by Gulf Bridge International (GBI) for asubmarine cable system connecting Egypt to Italy and put into service in Q12012. The GBI cable system is the first and only 100G repeatered subsea systemin commercial operation today. Developing further its 100G technology that hasincluded soft-decision FEC since 2011, Xtera has carried out numerous 100G fieldtrials in the past quarters on various types of cable systems with manyoperators in order to increase the performance of 100G reach on ultra-longdistances. Xtera`s 100G field trials were conducted on multiple subsea cable systems ofdifferent generations, made of various fiber types of different lengths.Regional, trans-Atlantic and trans-Pacific cable systems have been tested byXtera`s skillful and experienced testing teams. Accurate analysis of systemperformance is key for understanding Xtera`s 100G capabilities to furtherimprove our 100G technology for both upgrades and new builds. Another variant of 100G field trials consist of Optical Transmission Surveys(OTS) whose main purpose is to determine the maximum system capacity thatexisting subsea cable systems can support when upgraded with Xtera`s 100Gtechnologies. Because of the variety of fiber types and repeater generationsthat have been used for the past 20 years in different system designs andconfigurations, OTS is necessary to improve simulation tools as well as make thecapacity commitments reliable for upgrade projects. Xtera has been working on the upgrade of submarine cable systems since 2001 andcarried out its first commercial upgrade project in Q1 2006. Since then Xterahas been developing a unique experience and expertise to better understand thebehavior of cable systems when fed by higher and higher channel rates. Today,Xtera offers advanced 100G technology for both upgrade and new builds.
