H. Harano et al., 2.6 Gb/s 32-channel Dense Wavelength Division Multiplexing transmission system (SpectralWave 32), NEC RES DEV, 40(1), 1999, pp. 17-21
For the past few years, Dense Wavelength Division Multiplexing (DWDM), whic
h enables large transmission capacity and long distance transmission, has a
ttracted much attention in the world. We have developed the DWDM transmissi
on system featuring maximum 80 Gb/s (2.5 Gb/s 32-channel) transmission capa
city and 600 km transmission distance with optical line repeater to meet th
e market's demands. Upgrading to 64-channel DWDM transmission system has al
so been realized.
