The 1550nm High Power PM In-line Optical Isolator 30W is a compact, high performance light wave Polarization Maintaining component that does not change its polarization state. They’re characterized with low insertion loss, high isolation, high power handling, high return loss, excellent environmental stability and reliability. They are most often used to prevent any reflected light from entering the source, thus preventing any feedback problems; it has been widely used in fiber laser system.

PM and non-PM types are available, fiber can be customized, with power conditions of CW or Pulse and Power Handling of 5W, 10W, 20W, 30W, 50W can be customized.

If you do not see a standard isolator that meets your needs, we welcome the opportunity to review your desired specification and quote a custom isolator. Requests for custom fiber pigtails, different wavelengths and handling power of operation or other specific needs will be readily addressed. 

Performance Specifications

1. Above specification are for device without connector and may change without notice.
2. IL is 0.3 dB higher and RL is 5 dB lower, ER is 2dB lower (PM type) for each connector added.
3. The pass optical power is 2 W only for connector added, the connector is only used for performance testing at low power, higher power requires splicing fibers.
4. Type B: Both axis working, Type F: Fast axis blocked, the default is Type B if without request (Only for PM type)
5.  If there is pulse application, please be sure to inform us of pulse energy and peak power.
