Polarization
Maintaining
(PM)
Fiber-Optic
Circulator (PMFC)
Description: The three port in-line polarization maintaining (PM) fiber optic
circulator routes PM optical signals in a unidirectional sequential order from
port 1 to 2 and port 2 to 3 while maintaining the polarization with high
extinction ratio. It features low insertion loss, high isolation, high
extinction ratio, high return loss and high stability and reliability. The PM
circulator is package in a small size reliable in-line package compatible with
all demanding applications. |
