The 1310/1550 nm high power optical circulator is designed for high power applications. This non-reciprocal device redirects light at 1310/1550 nm wavelengths from port-to-port in only one direction while minimizing back reflection and back scattering in the reverse directions for any state of polarization. Employing Photonwares’s 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. This circulator can be made using a variety of fibers including HI980, HI1060, LMA and double cladding fibers.
