Features of High Power Fiber Optic Isolator

1. Polarization Independent

2. Low Insertion Loss

3. High Isolation and Return Loss

4. High Reliability and Stability

Note of High Power Fiber Optic Isolator

1. The high power optical isolator (polarization-independent fiber optic isolators, 1064/1053/1030/980 nm) 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.

3. 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.

4. For CW high-power optical interconnection, we recommend fusion splice without connectors.

5. For product customization or special requirements, please contact Lfiber’s sales department for availability.
