Coarse Wave Division Multiplexing (CWDM) modules combine or split up to 18 wavelengths into a single fiber. CWDM technology uses ITU standard 20nm spacing between the wavelengths, from 1270nm to 1610nm.
Our CWDM module has 4 to 18 channels. The central wavelength of each channel is specified to one of the ITU-T grid wavelengths.
The CWDM module features wide channel bandwidth (13nm). Its isolation is greater than 30dB for adjacent channels, and greater than 40dB for non-adjacent channels. The module also has high thermal stability to ensure reliable performance under different environment.Features:
- Based on proven thin-film filter technology
- Low insertion loss
- High channel isolation
- High stability and reliability
Applications:
- CWDM metro and access broadband networks
- CATV systems
- Fiber optic amplifiers
