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
