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.
