Product Details

Supports voice, data, and video services. The WDM passive components, based on thin film filter technology, combine all network services/signals over a single fiber. Low insertion loss and high isolation between channels ensures reliable network performance. WDMs are offered in our standard LGX® single wide module including up to (3) WDMs in (1) LGX® single wide module for high-density use. WDMs can also be ordered in ruggedized cassette, rack-mount 1RU, and steel mini tube type housings with standard and custom configurations upon request.


  • Excellent environmental & mechanical stability
  • High isolation
  • Low insertion loss & PDL
  • Premium grade components & connectivity
