Optical Fiber Circulator Description
Single Mode (SM) Optic Circulators are non-reciprocating,
one-directional, three-port devices that are used in a wide range
of optical setups and for numerous applications.
Because of its high isolation and low insertion loss, optical
circulators are widely used in advanced communication systems as
add-drop multiplexers, bi-directional pumps, and chromatic
dispersion compensation devices.
Circulator used to drop an optical channel from a DWDM system using
a Fiber Bragg Grating.
An optical circulator is analogous to an electronic circulator and
both perform similar functions.
An optical circulator is a three-port device that allows light to
travel in only one direction.
Circulators can also be used to send optical signals in two
directions down a single fiber. A circulator is located at both
ends of the fiber.
A signal entering 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.
