Coarse Wavelength Division Multiplexing (CWDM)

CWDM is a passive technology that allows for any protocol to be transported over the link, as long as it is at a specific wavelength (i.e. T1 over fiber at 1570nm transported alongside 10Gbps Ethernet at 1590nm). Because the multiplexers simply refract light at any network speed, regardless of the protocol being deployed, CWDM can help to future proof the networking infrastructure.
CWDM is a simple and affordable method to maximize existing fiber by decreasing the channel spacing between wavelengths. The benefits of CDWM include:

  • Passive equipment that uses no electrical power
  • Extended Temperature Range (0-70˚C)
  • Lower cost per channel than DWDM
  • Scalability to grow fiber capacity with little or no increased cost
  • Protocol transparent

Another benefit to the passive CWDM technology is that no configuration is necessary, which makes CWDM a low-cost and effortless technology to implement.
