1. Description:
CWDM is using optical multiplexer to different wavelengths of light to reuse the signals to single fiber transmission, the receiving end of the link, with the aid of photolysis multiplexer to mixed signal in the optical fiber signal is decomposed into different wavelengths, connected to the corresponding receiving equipment.
2. Features
1. Based on thin film filter technology and high wavelength stability
2. Low polarization dependent loss and high channel isolation
3. Flat and wide passband
4. Compact size and upgrade port is optional
5. Epoxy free optical path and excellent reliability
6. Telcordia GR-1221-CORE qualified and RoHS compliant
3. Applications
CWDM System
PON Networks
CATV Links
