High Power PM Optical Isolator
Description
The High Power PM Isolator (1310nm / 1550nm) from Lfiber is a premium optical component designed to suppress unwanted back reflections and feedback in high-power fiber optic systems. Built for robustness and precision, this isolator ensures stable optical signal transmission in demanding applications such as PM fiber lasers, amplifiers, and high-precision sensor systems. Available in both single-stage and dual-stage designs, it delivers excellent performance with low insertion loss (as low as 0.4 dB) and high isolation (up to 58 dB).
The device supports both “slow axis working & fast axis blocked” or “both axis working” configurations and is equipped with Polarization Maintaining (PM) Panda fiber for maximum signal fidelity. Engineered for power handling up to 20W CW and peak powers up to 20 kW, it is well-suited for cutting-edge communication systems and testing environments. The isolator is offered with customizable pigtails, connector types, and package formats to meet specific integration needs.
Backed by Lfiber’s commitment to quality and innovation, this isolator combines high extinction ratio, excellent return loss, and superior reliability for mission-critical photonics applications.
