Polarization-Maintaining (PM) 3-Port Optical Circulator (1310, 1480)

Ascentta™ Polarization-Maintaining (PM) 3-Port Optical Circulator (1310, 1480, 1550, 1590nm)

MSE Supplies offers Ascentta Polarization-Maintaining (PM) 3-Port Optical Circulator (1310, 1480, 1550, 1590nm). Our widely used three port fiber optic circulator is a compact, high performance optical device that transmits the signal from port 1 to port 2, and from port 2 to port 3 simultaneously. It can be used in DWDM systems with fiber gratings and other reflective components.
