Description
The Polarization-Maintaining (PM) Optical Circulator is non-reciprocating, unidirectional, three-port devices that are used in a wide range of optical setups. Available with a center wavelength of 1064, 1310 (O-Band), or 1550 nm (C-Band), these circulators are fast axis blocked and hence are designed to work with light that is launched into the slow axis.
The function of the high-power polarization-maintaining (PM) fiber optic circulator is to transmit a light signal from one port to the next sequential port with low loss, but at the same time to block any light transmission from one port to the previous port. By the use of the polarization-maintaining fiber (PMF), this high-power polarization maintaining optical circulator is capable of maintaining the same state of polarization (SOP) of the light. It can work on both slow-axis and fast-axis linear polarizations, or just transmit one principal polarization state with low loss in only one direction and block the orthogonal state in both directions.
