Product Description

PM DWDM Modules Designed to Telcordia and ITU Standards

Product Description

A PM DWDM module, or Polarization Maintaining Dense Wavelength Division Multiplexer module, is a device that can be used to add or drop wavelengths in a telecommunications network system. It can be used individually or in DWDM systems and sensor systems.

PM DWDM modules have the following features:

• Low temperature sensitivity
• Epoxy-free optical path
• Low insertion loss
• Wide pass band
• High channel isolation
• High extinction ratio
• High stability and reliability 

Applications

• CATV Router

  GPON Network

  DWDM System
