Description:
Polarization Maintaining Faraday Mirror is a fiber optic passive device that provides a 45-or-90 -degree rotation regarding to the polarization state of the input light. The polarization maintaining faraday mirror (PMFM) offers excellent performance including the lowest possible insertion loss and environmental stability.
Features:
Low insertion loss
High return loss
Low polarization sensitivity
Compact size
Applications:
CATV fiber optic links
Fiber optical system testing
Fiber optical LAN systems
