Project Description

1.0μm TGG Based Optical Circulator

The TGG Based 1030nm Optical Circulator is a high-performance light-wave component that routes incoming signals from Port 1 to Port 2, and incoming Port 2 signals to Port 3. They’re characterized with low insertion loss, high isolation, high power handling, high return loss, low PDL, low PMD, excellent environmental stability and reliability. They are ideal for fiber laser and instrumentation applications.

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

  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 or 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. If there is pulse application, please be sure to inform us of pulse energy and peak power.

Order information

P/N: PIOC-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.
