High Power PM Optical Isolator
Description
The High Power PM Optical Isolator (1310nm/1550nm PM isolator) is a fiber optic component that transmits light in only one direction, thereby preventing reflected light from returning back to the source. It is built with PM Panda fibers and capable of maintaining a well-defined state of polarization (SOP) of the light. This High Power PM Optical Isolator (fiber-coupled PM isolator) can be single or double/dual stage depending on the degree of required optical isolation of the propagating light. It’s a good choice in many laser applications, since back-reflected light often have deleterious effects on the operating conditions of optical devices.
Notes:
1.The High Power PM Optical Isolator (1310nm/1550nm PM isolator) is customizable, and the above specifications are subject to change without notice.
2.For device with connectors, IL is 0.3dB higher, RL is 5.0dB lower, ER is 2.0dB lower.
3.Unless otherwise specified, the slow axis of the fiber is aligned with the key of the PM fiber connector.
4.Slow axis working and fast axis blocked as standard, while operating on both the slow and fast axis available on request.
5.Bare fiber should not support the weight of the connector. So that if any connectors needed, for the pigtail type it’s better to choose the 900μm loose tube jacket instead of the 250μm bare fiber.
6.For CW high-power optical interconnection, we recommend fusion splice without connectors.
7.For product customization or special requirements, please contact Lfiber’s sales department for availability.

Frequently Asked Questions
The High Power PM Optical Isolator transmits light in only one direction, preventing reflected light from returning back to the source.
Single-stage isolators provide a lower degree of optical isolation compared to dual-stage isolators.
The High Power PM Optical Isolator is commonly used in fiber laser testing instruments, PM fiber sensors, and polarization maintaining (PM) fiber amplifiers.
The typical insertion loss at 23℃ is 0.4 dB for single-stage and 0.5 dB for dual-stage isolators.
Yes, the High Power PM Isolator is customizable. Customers can contact Lfiber's sales department for customization or special requirements.
