The Polarization Maintaining Faraday Rotator Mirror are ideal for polarization maintaining fiber amplifiers, fiber lasers, high speed communication system and instrumentation applications.
The Polarization Maintaining Faraday Rotator Mirror are characterized with low IL, high return loss, high extinction ratio and excellent environmental stability and reliability. They are ideal for polarization maintaining fiber amplifiers, fiber lasers, high speed communication system and instrumentation applications.
Thermal and mechanical perturbations introduced to a standard,single mode fiber often cause variations in the state of polarization (SOP) of the guided light. These changes can adversely affect the performance of many different types of systems. Retaining the SOP using polarization-maintaining (PM) fiber can reduce or eliminate these adverse effects, but PM fiber is costly and often difficult to incorporate effectively.
The Faraday Rotator Mirror (FRM) is a low-cost, passive device that correctly compensates for such SOP variations. This simple,easily installed component works to neutralize the effects caused by changes in the SOP, allowing engineers greater control over the design of systems such as fiber sensors, erbium-doped fiber amplifiers, and tunable fiber lasers.
If you do not see a standard PM Faraday Rotator Mirror that meets your needs, we welcome the opportunity to review your desired specification and quote a custom Faraday Rotator Mirror. Requests for custom fiber pigtails, different wavelengths and handling power of operation or other specific needs will be readily addressed.
