CWDM Module
Our optical CWDM devices utilize thin-film filter technology and are available in various wavelength combinations based on the entire wavelength spectrum (1310nm ~ 1610nm in 20nm increments) defined by the ITU G.694.2 CWDM standard. These CWDM devices are available in two main configurations: Multiplexer / demultiplexer (mux / demux) modules and optical add / drop multiplexer (OADM) modules.
The mux / demux devices are available in 4, 8 and 16 channel configurations. These modules passively multiplex the optical signal outputs from 4 or more electronic devices, send them over a single optical fiber and then de-multiplex the signals into separate, distinct signals for input into electronic devices at the other end of the fiber optic link.
The optical add / drop multiplexer modules provide the ability to add or drop a single wavelength or multi-wavelengths from a fully multiplexed optical signal. This allows intermediate locations between remote sites to access the common, point-to-point fiber segment linking them. Wavelengths not dropped, pass-through the OADM and continue on in the direction of the remote site. Additional selected wavelengths can be added or dropped by successive OADMS as needed.
The CWDM add / drop multiplexer allows a single channel (CWDM wavelength) to be inserted / extracted from the composite CWDM trunk. There are two versions of the OADM, one does add / drop in both directions, the second does add / drop in a single direction.
