Single Mode Fiber Optic Circulators

Ideal-photonics's 1550 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. These circulators have a maximum power handling of 500 mW (CW). Fiber optic circulators are non-reciprocating, one directional, three-portdevices that are used in a wide range of optical setups and for numerous applications. 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 entered to Port 1 will exit Port 2, while a signal entering Port 2 will exit Port 3 all 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.
