Optical Circulator

An optical circulator is a unidirectional three-port device with irreversible transmission that allows light to travel in a specific direction. According to their physical principles, circulators can be divided into non-polarization-maintaining circulators and polarization-maintaining circulators. The Vsunlight Tri-Port or four-Port Optical Circulator is a passive device that transmits high-frequency signal energy in one direction, ensuring that light travels in only one direction. It has the characteristics of low insertion loss, high isolation, and low polarization-related loss. The product has stable performance and strong reliability. All versions are designed for use in an outdoor environment within a temperature range of –10 ℃ to +70 ℃.

Ordering Information

Optical circulator light path diagram

Optical circulator is divided into two types: three port and four port, The flow direction of signal light in it is

Port 1 →Port 2 →Port 3 → Port1, Port1 →Port2 →Port 3 →Port 4 → Port1, otherwise, the signal light is isolated.
