NICE, France -- Huawei, a leading global information and communications technology (ICT) solutions provider, today launched the world's first 1T WDM line card at the Next Generation Optical Networking Forum, the most important optical conference in Europe. This marks a new milestone in the high-speed transmission field.
Thanks to the ever-growing pressure for more bandwidth, the industry's interest in developing terabit-level WDM line cards has continued to increase. The long-awaited line card finally made its debut at the forum, where Huawei demonstrated its performance on the OSN 9800, its flagship product. The line card delivered 800-km transmission based on common G.652 fibers and erbium-doped fiber amplifiers (EDFAs), but without regeneration. It can encapsulate client signals of any rate into an OTN-based 1 Tbit/s channel for transmission.
The line card adopts the cutting-edge Optical Digital Signal Processing (oDSP) algorithm for processing high-speed signals. Switching between short-haul metro mode (ultra-high-capacity transmission) and ultra-long-haul backbone mode (ultra-long-haul transmission) is easily implemented through software-based modulation scheme reconfiguration. The short-haul metro mode reaches a capacity of more than 20 Tbit/s per fiber, nearly triple that of current mainstream commercial 100G systems. The ultra-long-haul backbone mode supports more than 10 Tbit/s transmission per fiber over a distance of 3,000 km.
