The high power PM fiber optical isolator (1064/1030/980 nm polarization-maintaining optical fiber isolator) is one of the most important passive components. The function of a PM optical isolator is to let a light beam pass through in one direction, that is, the forward direction only, like a one-way traffic. At the same time, the PM optical isolator is able to maintain a well-defined state of polarization (SOP) of the light. The high power PM Isolator (polarization maintaining isolator) is used to prevent reflected light that causes undesirable effects such as frequency instability in laser sources and parasitic oscillation in optical amplifiers. 

Notes:

• The high power pm fiber optical isolator is customizable, and the above specifications are subject to change without notice.
• For CW high-power optical interconnection, we recommend fusion splice without connectors.
• For device with connectors, IL is 0.3dB higher, RL is 5.0dB lower, ER is 2.0dB lower.
• Unless otherwise specified, the slow axis of the fiber is aligned with the key of the PM fiber connector.
• Slow axis working and fast axis blocked as standard, while operating on both the slow and fast axis available on request.
• 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.
