The F-FRM-2-JK-FP Fiber Optic Faraday Rotator Mirror is a polarization rotation mirror designed for fiber optic networks and measurement applications. Upon reflection, the state of polarization (SOP) rotates 90 ° from that of the input light. A unique property of the F-FRM Series is that at any point along the fiber, the SOPs of the forward and backward optical waves are always orthogonal to each other, regardless of the birefringence of the fiber. When used properly, the Fiber Optic Faraday Rotator Mirror can help eliminate polarization sensitivity in optical fiber systems. Applications include eliminating polarization-induced fluctuations in fiber based interferometers, fiber laser systems, Brillouin amplifier systems, and remote fiber optic antenna systems.
The epoxy-free optical path offers low insertion loss, low polarization dependent loss (PDL) and high temperature stability. This device is ideal for polarization control in fiber laser systems, fiber sensors and fiber interferometers, as well as for polarization sensitivity elimination in bulk diffraction grating systems. This 1550 nm SMF-28 pigtailed version has approximately 1 m long fiber pigtails with 900 μm loose tube and FC/PC connectors.

F-FRM-2-JK-FP光纤法拉第旋转镜是为光纤网络和测量应用而设计的偏振旋转镜。反射后,极化的状态(SOP)旋转90°与输入光。F-FRM系列的一个独特特性是，在沿光纤的任何一点上，无论光纤的双折射如何，正向和反向光波的SOPs总是相互正交的。如果使用得当，光纤法拉第旋转镜可以帮助消除光纤系统的偏振灵敏度。应用包括消除基于光纤的干涉仪、光纤激光系统、布里渊放大器系统和远程光纤天线系统中的偏振诱导波动。
