Innovative subsea solutions providers are now testing advanced technologies that can eliminate risk while delivering the best end-to-end systems for their customers. With so many new transoceanic and regional systems either under construction or in the planning stages across the world, this is good news for subsea network owner-operators and their clients.

Just recently, Xtera® announced the completion of interoperability testing with Infinera. By connecting Infinera’s Submarine Line Terminal Equipment (SLTE) solution to an Xtera line system during a laboratory trial, Xtera was able to prove the truly open nature of its Open System Gateway (OSG) product family. Through a series of subsea tests and simulations, Xtera was able to demonstrate spectrum sharing, compatibility and its ability to operate with the Infinera terminal.

“Today’s customers are looking for systems which combine the most advanced technology available; the move towards provision of disaggregated subsea solutions demonstrates this, stated Keith Henderson, Xtera’s Founder and Chief Executive Officer. “The success of these interoperability tests will give customers comfort that selecting Xtera technology for their wet plant can provide them with a proven end-to-end solution using industry leading SLTE platforms.”

Scott Jackson, Vice President of Infinera’s Subsea Business Group, also commented on the success of the interoperability testing.

“Infinera is continually enhancing our solutions to deliver the best capacity-reach performance, and we lead the way in Open SLTE solutions,” added Jackson. “Adding compatibility with Xtera’s advanced line systems further illustrates our commitment to Open Systems and shows how Open SLTEs can eliminate risk while delivering the best system solutions for our customers.”

During the tests, the team analyzed the transmission performance of Infinera’s XTS-3300 through Xtera’s wideband hybrid Raman-EDFA repeaters using 16-QAM modulation format. These trials showcased how Xtera’s Virtual Fiber Gateway (VFG) can allow multiple vendors’ equipment to independently share spectrum. It also proved the resilience of XTS-3300 to strong Line Monitoring Equipment (LME) signals.
