1310nm PM Faraday Mirror

The PM 1310nm Faraday Mirror is a passive device that provides 45- or 90-degree rotation regarding to the polarization state of the input light. It is a fiber optic polarization rotation mirror designed for fiber optic networks and measurement applications. The device can help to eliminate polarization sensitivity of an optical fiber system.

Features

  • High Isolation
  • Low Insertion Loss
  • High Return loss
  • Compact Size
  • Epoxy Free Optical Path

Applications

  • Fiber Optical Amplifier
  • CATV Fiber optic Links
  • Fiber optic Systems Testing
  • Fiber optic LAN Systems
  • Telecommunications

The PM 1310nm Faraday Mirror is a passive device that provides 45- or 90-degree rotation regarding to the polarization state of the input light. It is a fiber optic polarization rotation mirror designed for fiber optic networks and measurement applications. The device can help to eliminate polarization sensitivity of an optical fiber system. Applications include eliminating polarization induced fluctuations in fiber interferometers, Brillouin amplifier systems, fiber laser systems, and fiber optic antenna remoting systems. Our Faraday Mirror is optical path epoxy free and thus offers low insertion loss and high temperature stability.
