Coarse Wavelength Division Multiplexers Module (4/8 Channels)

The 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 20 nm channel spacing. It has low insertion loss, low PDL, high isolation and good thermal stability.
