Do you know what is a fiber optic circulator?

2022-03-30
An optical fiber circulator is a multi-port device that transmits the incident wave entering any port to the next port in sequence according to the direction determined by the static bias magnetic field.

A fiber optic circulator, also known as an isolator, is a non-reversible device with several ends. Its distinctive feature is that it can transmit high-frequency signal energy in one direction. It is divided into micro-optical fibers and electronic circulators.

The incident wave entering any of its ports is transmitted to the multi-port device of the next port in the order determined by the static bias magnetic field. A circulator is a non-reciprocal device with several terminals.
