Project Description
TGG Based 635nm Optical Circulator
The TGG Based 635nm 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, 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.

Order information
P/N: PIOC(PMOC)-①-②-③-④-⑤-⑥(PMOC-B/F: Polarization Maintaining Optical Circulator)
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.
