Product Description
CWDMs (Coarse Wavelength Division Multiplexers) cost-effectively utilize your existing fiber plant bandwidth by multiplexing up to 18 channels. Montclair offers 3 types of CWDM Mux/Demux solutions: Unidirectional transmission in one direction via one fiber, Bidirectional transmission in both directions via two fibers, and Bidirectional transmission in both directions via one fiber (below illustrates each of the 3 types of CWDM Mux/Demux solutions). Montclair passive CWDMs are available with an optional upgrade/expansion port to allow for incremental future channel add-ons.
Features
- High demux channel isolation
