Coarse Wavelength Division Multiplexer
In fiber-optic communications, wavelength-division multiplexing (WDM) is a technology which multiplexes a number of optical carrier signals onto a single model fiber.
Advantages of the coarse wavelength division multiplexer:
- Low Insertion Loss and High Isolation
- Good Wavelength Stability
- Optical path epoxy-free with good environment stability
- Bell-core 1221 compliant
The multiplexer module combines several wavelengths (channels) traveling in each separate single mode fiber into one single mode fiber, and the same module separates each specific wavelengths traveling in the common single mode fiber into wavelength, each traveling in a separate single mode fibers.
The CWDM Modules are based on thin-film filter technology. This proven technology offers wide channel bandwidth, flexible channel configuration, low insertion loss and high isolation.
SC/APC is used as standard. Other connector types are available on request.
