Providing an ultra-high-speed transport link between London and Amsterdam – the largest-bandwidth-demanding cities in the network – the commercial application of coherent 100G services on the network helps KPN International prepare for future network service growth. To address the challenges that come from the rise in high-bandwidth services, KPN International and Huawei have made longstanding and collaborative efforts in the coherent 100G transport field.
The coherent 100G technology is the latest technology for transmitting high-speed 100G services, providing ultra-large dispersion tolerance and polarization mode dispersion tolerance. With this technology, 100G services become more adapted to fiber transmission. Services can be transmitted at a higher rate over a longer distance. At an astonishing transmission rate of eight Tb/s, it takes only one second to download 240 DVD movies, each of which is two hours long.
Huawei’s solution for KPN International enables hybrid transmission of 100G services and the existing 10G/40G services on the network, smoothly upgrading the network while not affecting ongoing services. The solution also creates a tenfold increase in the service rate of a single wavelength, which helps KPN International effectively resolve the large-bandwidth challenges and maximize return on investment. With support for G.652 and G.655 fibers, the Huawei coherent 100G solution provides 100G service transmissions over a distance of 613km without having to use an electrical regeneration site, demonstrating excellent performance on the KPN International WDM network.
