3 Ports 1310/1550nm Fiber Optics Components Polarization Insensitive Optical Circulator
Description
GEZHI's 3ports Optical Circulator allows light to travel in only
one direction. A signal entering to Port 1 will exit Port 2 with
minimal loss, while a signal entering Port 2 will exit Port 3 with
minimal loss. Light entering port 2 experiences a large amount of
loss at port 1, and light entering port 3 experiences a large
amount of loss at ports 2 and 1. Optical circulators are
non-reciprocal devices. This means that any changes in the
properties of the light caused by passing through the device are
not reversed by traveling in the opposite direction.
Optical Circulator is widely used in advanced communication systems
and fiber-optical sensor systems.
Characteristics
Applications
Application Diagram
Circulator used to drop an optical channel from a DWDM system using
a Fiber Bragg Grating.
As the picture shows: The input DWDM channels are coupled into Port
1 of the device with a FBG device connected to Port 2. The single
wavelength reflected from the FBG then reenters the Circulator in
Port 2 and is routed accordingly to Port 3. The remaining signals
pass through the FBG and exit on the top fiber.
Circulator can be used to send optical signals through a single
fiber in two directions.
As the picture shows: A Circulator is located at both ends of the
fiber. Each Circulator functions to add a signal in one direction
while removing the signal in the other. See the example to the
left.
