3 Port 1550nm FCAPC 1550nm Circulator

                                                                           3 Port FCAPC PM 1550nm Circulator

An optical circulator is a device that allows light to travel in only one direction. It is widely applied in high-precision optical systems such as fiber sensing, fiber lasers, dispersion compensation, and quantum communication.

OPTICO's polarization-maintaining (PM) optical circulators are non-reciprocating, unidirectional devices that can be used in a variety of optical applications. This special circulator ia centered at 1550 nm (C-band). Its core structure combines Faraday rotatory materials with birefringent crystals, ensuring unidirectional transmission of optical signals from port 1 to port 2 to port 3, achieving an extinction ratio of up to 20dB or higher. 

In this catalog, OPTICO offers customization of a wide range of circulators,  like 3-port, 4-port, single-mode, conventional or polarization maintaining,  varied wavelengths, high power etc.
