Cisco today announced that it has successfully tested its NCS 1004 platform
on a 6,605-kilometer MAREA submarine cable connecting Virginia Beach, USA, and Bilbao, Spain.
Designed to demonstrate the ability to provide increased transatlantic bandwidth, the test tested several channel capacity combinations to maximize cable performance and spectral efficiency
.
Cisco said that in the Virginia to Bilbao trial, it demonstrated error-free performance of 400G; The spectral efficiency of these channels reached a record 6.
445 bits per second (b/s/Hz) per hertz, while a spectral efficiency
of 4.
52b/s/Hz was tested at loopback conditions of more than 13,200 km.
Bill Gartner, Senior Vice President and General Manager of Cisco's Optics and Optics Division, commented, "We demonstrated that MAREA can use 24.
7Tbps of capacity space
.
We also tested the full loopback mode (from Bilbao to Virginia and back to Bilbao) and showed that it was possible to double the distance of 18.
5Tbps with sufficient system margin
.
The MAREA submarine cable system is a 6,600-kilometer transatlantic communications system from Bilbao (Spain) to Virginia (USA), jointly developed
by Telxius, Facebook and Microsoft.
Telxius, a global telecommunications infrastructure company that is a subsidiary of Telefonica, joined the project in May 2016 and is responsible for managing the construction process and operations, and began deploying the system in August
.
In February 2018, the cable system went into commercial operation with eight fiber pairs with an initial design capacity of 160Tbps, which will reach 200 Tbps
when the expansion is completed.
