3 Port Single Mode Fiber Optic Circulators 1310nm or 1550nm Optical Circulator

GEZHI 3 port Polarization Insensitive Optical Circulator that are used to direct the optical signal from one port to another port and in one direction only. This action prevents the signal from propagating in an unintended direction. Optical circulators can be used to achieve bi-directional optical signal transmission over a single fiber. The Fiber Optical circulators is commonly used in WDM networks, chromatic dispersion compensation, polarization mode dispersion, optical add-drop modules (DWDM OADM), OTDR optical amplifiers and fibre sensing applications.

3 port Polarization Insensitive Optical Circulator with FC/APC connector

In a 3-port circulator a signal is transmitted from port 1 to port 2, another signal is transmitted from port 2 to port 3 and, finally, a third signal can be transmitted from port 3 to port 1. This behavior is represented by the following.

GEZHI 3 Port Optical Circulator can be used to send optical signals through a single fiber in two directions.
