Isolators & Circulators

PM Fiber Optical Circulator 1550nm

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.

System integration

Integration and compatibility

Use these checks to connect PM Fiber Optical Circulator 1550nm to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.

Optical interface and fiber: 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 and loss budget: 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.
