Compact size TGG Based PM Optical Isolator-780/795/808/840/850nm

The Optical Isolator is characterized with low insertion loss, high isolation, high return loss, excellent environmental stability and reliability. It has been widely used in lasers, transmitters and other fiber optics communication equipment to suppress back reflection and back scattering.

Features

  • Low Insertion Loss
  • High Extinction Ratio
  • High Power Handling
  • Low Cost
  • High Reliability

Applications

  • Fiber Amplifiers
  • Fiber lasers
  • Test and Measurement
  • Communications System

The Optical Isolator is characterized with low insertion loss, high isolation, high return loss, excellent environmental stability and reliability. It has been widely used in lasers, transmitters and other fiber optics communication equipment to suppress back reflection and back scattering.

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.

  1. Above specifications are for device without connector.
  2. For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower and ER will be 2dB lower. The default connector key is aligned to slow axis. Power transmits through the connector less than 2W.
  3. If there is pulse application, please be sure to inform us of pulse energy and peak power.
  4. Type B: Both axis working, Type F: Fast axis blocked, the default is Type B if without request.

Order information

P/N: CTPMISO-B/F -①-②-③-④-⑤-⑥-⑦

When you inquire, please provide the correct P/N number according to our ordering information and attach the appropriate description would be better. If need any connector, we do not recommend choosing a 250μm bare fiber pigtail. For high power applications, we recommend direct splicing without connectors.
