Overview
The FRM is a pigtailed fiber-optic Faraday rotator mirror from the General Photonics passive component line now offered by Luna. It is part of a group of fiber-coupled passive components that are available with SM or PM fiber at 1550, 1310 or 1064 nm.
A Faraday rotator mirror reflects light with its state of polarization rotated by 90° relative to the input light. Because the forward and reflected light stay orthogonally polarized at every point along the fiber, whatever the fiber's birefringence, a correctly used device can remove polarization sensitivity from optical fiber systems.
The optical path of the FRM is epoxy free. The manufacturer cites low insertion loss and high temperature stability as the result. A NoTail version (NFRM) is offered for setups where pigtail handling and extra optical path delay are a concern.
The manufacturer lists the product as discontinued.
