S C L Wideband WDM MUX DEMUX 3 Port Polarization Insensitive Optical Circulator
3 Port Polarization Insensitive Optical Circulator 1310nm, 1550nm or S, C, L Wideband
Description
3 Port Polarization Insensitive Optical Circulator manufactured by ANC International Co., Limited is a three-terminal device. Terminal 1 is the input port and terminal 2 is the output port, while the reflected signal back into terminal 2 will be redirected to terminal 3 instead of terminal 1. Optical circulator has become one of the indispensable elements in advanced optical communication systems, especially WDM systems.The function of an optical circulator is to transmit a lightwave from one port to the next sequential port with a maximum intensity, but at the same time to block any light transmission from one port to the previous port. Optical circulators are based on the nonreciprocal polarization rotation of the Faraday effect.
Polarization insensitive optical circulator utilizes proprietary designs and metal bonding micro optics packaging. It provides low insertion loss, broad band high isolation, low PDL, excellent temperature stability and optical path epoxy free. It can be used for wavelength add/drop, dispersion compensation and EDFA application
