Coarse Wavelength Division Multiplexer Module (4 channel / 8channel) | |
Coarse WDM Module is expanding the bandwidth of Metro/Access Networks. The 4-channel and 8-channel CWDM modules are based on Coarse Wavelength Division Multiplexer devices. They can act as MUX/DEMUX with 20nm channel spacing. It has low insertion loss, low PDL, high isolation and good thermal stability. |
