1U 19 Rack Mount 8 Channel CWDM Mux Demux Module For Fiber Optical Amplifier
8 Channels 100GHz Mux Demux In 1U 19 Rack With LC UPC or APC Interface For FTTX CATV and Data Center is usually used for long-haul transmission where wavelengths are packed tightly together over the C-band, up to 48 wavelengths in 100GHz grid(0.8nm) and 96 wavelengths in 50GHz grid(0.4nm). It's protocol transparent and suit applications including 10/1G Ethernet, SDH/SONET, 16/8/4/2/1G Fibre Channel, FTTx and CATV.
The term WDM is commonly applied to an optical carrier, which is typically described by its wavelength, whereas frequency-division multiplexing typically applies to a radio carrier which is more often described by frequency
WDM, CWDM and DWDM are based on the same concept of using multiple wavelengths of light on a single fiber but differ in the spacing of the wavelengths, number of channels, and the ability to amplify the multiplexed signals in the optical space. EDFA provide an efficient wideband amplification for the C-band, Raman amplification adds a mechanism for amplification in the L-band. For CWDM, wideband optical amplification is not available, limiting the optical spans to several tens of kilometres.
