Product Description

500mW Max. Power Handling Pm CWDM Modules 
Product Description
PM CWDM modules are polarization-maintaining optical fiber circulators and isolators that are used in Coarse Wavelength Division Multiplexing (CWDM) systems. CWDM is a low-cost technology that combines multiple signals at different wavelengths into a single fiber optic cable for transmission.

Features

  • High Return Loss
  • Wide Transmission Width
  • High Stability & Reliability
  • Low Insertion Loss & High lsolation

Applications

  • CWDM system
  • CWDM/OADM module
  • CWDM/OADM network
