Isolators & Circulators
The OC Series 1310/1550 Optical Circulators are non-reciprocal devices that redirect light at 1310/1550 nm from port-to-port in only one direction while minimizing back reflection and back scattering in the reverse directions for any polarization state. Employing Our advanced micro-optics design, it features low insertion loss, low polarization sensitivity, high isolation, compact structure, and high stability. The excellent characteristics of this product make it an ideal choice for application in fiber amplifier systems, pump laser diodes, and optical fiber sensors. It is possible to produce a circulator with complete circulation at an exceptionally high cost.

Application context
Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.
PM Fiber Optical Circulator 1550nm: Laser source protection depends on preserving the optical budget through the complete path. The 1520~1580 nm wavelength specification sets source and detector compatibility. The fiber/interface entry (PM1550, PM1310) must match the connected components.
PM Fiber Optical Circulator 1550nm: Bidirectional signal routing depends on preserving the optical budget through the complete path. The 1520~1580 nm wavelength specification sets source and detector compatibility. The fiber/interface entry (PM1550, PM1310) must match the connected components.

Technical FAQ
Fiber Type: PM1550, PM1310 · Fiber Cover: 900um loose tube. Specify connector polish and fiber architecture together. FC/PC, FC/APC and SMA interfaces, and single-mode, multimode and polarization-maintaining fibers, impose different return-loss, mode-field and alignment requirements.
Wavelength: 1520~1580 nm. Check the Isolators & Circulators passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.
Share your wavelength, fiber type, connector, power handling and control requirements and we will qualify the matching configuration and part number.
