Huawei, a leading global information and communications technology (ICT) solutions provider, today announced world’s first 400G long-haul DWDM system boasting the industry’s largest transmission capacity at OFC/NFOEC 2012. The 400G DWDM system provides a capacity of up to 20 Tbit/s over a single fiber (C-band) and a transmission distance spanning 1,000 km without electrical regeneration. The DWDM technology goes beyond 100G with the rapid expansion of broadband services. The 400G DWDM marks another major breakthrough in the high-speed transport field.

Bolstered by the mature technologies available, the 400G DWDM is regarded as the next-generation DWDM system for deploying ubiquitous ultra-broadband networks. The 400G DWDM prototype employs the cutting-edge SD-FEC, unique coherent algorithm, and high-performance optical modules. Huawei showcased the access of 400GE and 4×100GE services and new OTN technology at the OTU-5 level. The prototype can be applied over the Huawei WDM/OTM platform to allow for smooth evolution from 40G/100G.
