Product Description

Polarization Maintaining DWDM Module with Low Insertion Loss

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

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. 

 

DWDM is often used by telecommunications, cable, and data centers as part of their optical transport network. DWDM technology is suitable for long-distance and high-capacity networks, such as backbone or core networks.

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
