Product Description

Efficient PM DWDM Modules to Enhance Optical Transport Network

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 are manufactured using thin film filter (TFF) technology and advanced packaging technology. They are designed and manufactured to Telcordial and ITU standards.

Features

• Low Insertion Loss

  High stability and reliability

  High Return Loss & High lsolation

  Good channel-to-channel consistency

Applications

• CATV Router

  GPON Network

  DWDM System
