2.5G-32CH DENSE WAVELENGTH DIVISION MULTIPLEXING SYSTEM (SYSTEM (SPECTRAL WAVE32)

摘要

In recent years, dense wavelength division multiplexing, which enables large transmission capacity and long distance transmission, has attracted the attention of the world wide markets. NEC has developed the DWDM(Dense Wave-length Division Multiplexing) featuring maximum 80Gbit/s transmission capacity which can meet the market's demands. This system converts maximum 32 channels of 2.5Gbit/s optical signals into signals for the DWDM and multiplexes them at 100GHz intervals. After that, it also enbloc amplifies and sends them to transmission line of single-mode fiber. Maximum 4 optical transmission line repeaters can be mounted on optical transmission line. Transmission distance is 80km per span and maximum transmission distance is 400km per 5 spans.
