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.
PM Optical Circulator is a 3 port fiber optic device build with PM panda fiber, transmits signal from port1 to port 2 and another signal from port 2 to port 3 while maintaining the polarization. PM Circulator features low insertion loss, high isolation between ports, low PDL, high extinction ratio, high reliability and stability. The device can be built with 250um bare fiber pigtails, 900um pigtails or 3mm cable.
