Telecommunications equipment maker T8 announced today it has set a new record for data transmission over long distances, transmitting 200 Gb/s per channel over 520 kilometers of Corning® TXF™ fiber and Corning® SMF-28® ULL fiber. The demonstration used T8’s high-speed multiservice and multiprotocol dense wavelength division multiplexing (DWDM) platform, Volga.
The achievement demonstrates how Corning Incorporated’s (NYSE:GLW) innovative fibers and T8’s transponder technology combined to enable transmission of more data over longer distances than ever before – offering potential benefits to network operators in remote areas with challenging terrain.
This result was achieved with forward and backward remote optically pumped amplifiers (ROPAs) in combination with co- and counter-propagating Raman amplifiers without the use of intermediate electrical power supply points. Using this distinctive combination, service providers and enterprises can now achieve ultra-high capacity and low latency, at a lower cost per bit.
“There are many long-distance routes in Russia that might benefit from this system design,” said Vladimir Treshchikov, general director, T8. “Corning’s fibers extended our system’s unrepeated reach by 90-100 kilometers compared to a standard single-mode fiber. Our experiment showed that T8’s state-of-the-art transponders allow transmission of a 200G signal over almost the same distances as 100G. This is possible due to the use of the DP-QPSK format with a high symbol rate (56.8 GBaud).”
Volga is a high-speed multiservice DWDM platform for backbone and regional optic fiber communications. It supports up to 400G per channel, 20T per fiber. Key customers for Volga are telecommunication operators and data centers. The Volga platform has EC declaration of conformity and complies with the requirements of the European Union.
“Corning is pleased to collaborate with T8 to demonstrate such an innovative combination of 200G transmission equipment with our advanced, high-data-rate fibers. It’s an example of how we work alongside industry leaders around the world to solve tough technology challenges,” said Sergey Akopov, optical fiber technical director, Russia region, Corning Incorporated. “Russia is a vast country with challenging terrain – such as remote areas with limited or no access to electricity. Here, and in similar geographic areas, Corning brings value with our long-haul fiber offerings, helping our customers reduce their capital and operational expenditures.”
TXF fiber is compliant with ITU-T Recommendation G.654.E and is optimized for long-haul terrestrial networks with a large effective area and cut-off wavelength shifted to just below the loss-minimized C-band region. In addition, SMF-28 ULL fiber features the lowest attenuation specification of any commercially available ITU-T Recommendation G.652-compliant fiber while maintaining compatibility with the installed base of other single-mode fibers. Using standard G.652 fibers, the maximum transmission distance would be 460 km.
