Optical Fiber Circulator Product Name
SM Optical Circulators, 1310 nm Optical Fiber Circulator
single-mode type
Optical Fiber Circulator Description
1310 nm SM Fiber Optic Circulators are available unterminated, with
FC/PC connectors, or with FC/APC connectors. The FC/PC and FC/APC
connectors have a 2 mm narrow key.
Our CIR1310, CIR1310-FC and CIR1310-APC circulators have a maximum
power handling of 300 mW (CW).
The CIR-1310-50-APC broadband fiber optic circulator is
specifically designed for OCT applications. This circulator boasts
a broader wavelength range than our standard 1310 nm SM fiber
optical circulator and has a maximum power handling of 500 mW (CW).
Circulators can be used to send optical signals through a single
fiber in two directions.
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.
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.
