Polarization Maintaining Fiber Optic PM Filter WDM for ICT AI Computing

Polarization Maintaining Fiber Optic PM Filter WDM for ICT AI Computing
PM Filter WDM Overview
Polarization Maintaining Filter WDM multiplexes PM signals and maintains the output polarization with high extinction ratio using advanced micro-optic filter technology. All input and output fibers are polarization maintaining. It utilizes advanced filter technology to yield wide-band, low insertion loss, high polarization extinction, and high return loss in a compact package. These devices are ideal for PM fiber amplifiers, fiber lasers, and instrumentation applications.
Key Features
  • Low Insertion Loss
  • High Return Loss
  • High Stability and Reliability
