980/1550 Fused CWDM Module 1×16 Channel ABS Type

  • Low Insertion Loss
  • Wide Pass Band
  • High Channel Isolation
  • High Stability and Reliability
  • Epoxy Free on Optical Path

Coarse Wavelength Division Multiplexer is based on thin-film filter technology. With low-cost and compact dimension, it is widely used in network transmission.

The CWDM module is made by fused fiber technology offering advantageous attributes of low cost, low insertion loss, and high stability. It comes with a matching pair. It is ideally suited for CATV links.

CWDM Mux/Demux Modules are available in 4, 8 and 16 channel configurations. These modules passively multiplex the optical signal outputs from 4 or more electronic devices, send them over a single optical fiber and then de-multiplex the signals into separate, distinct signals for input into electronic devices at the other end of the fiber optic link.



  • Low insertion loss
  • High channel isolation
  • Telcordia GR-1221-CORE Compliant
