200GHz dense wavelength division multiplexer (DWDM) utilizes thin film coating technology and proprietary design of non-flux metal bonding micro optics packaging to achieve optical add and drop at the ITU wavelengths. It provides ITU channel center wavelength, low insertion loss, high channel isolation, wide pass band, low temperature sensitivity and epoxy free optical path. It can be used for wavelength add/drop in telecommunication network system.
Our DWDM Mux/Demux products provide up to 24-channel Multiplexing on a single fiber. Standard DWDM Mux/Demux package type include: ABS box package, LGX package and 19” 1U rack-mount.
Our DWDM products are Telcordia qualification tested.

- The above specification is without connector.
- IL is 0.3 dB higher and RL is 5 dB lower for each connector and adapter added.
- Channel count is from low to high for mux and high to low for demux if mux & demux are packaged in one cassette.
- Other specifications can be made on customer request.
