    摘要: An optical circulator outputs an optical signal entered through its port A from its port B. A fiber collimator makes the optical signal spread out from the port B of the optical circulator into a collimated beam and applies it to a beam splitter. The beam splitter is disposed at an angle of 45° to the optical axis. Around of the beam splitter, total reflection mirrors are disposed in three directions per angle of 90° except for the direction in which the fiber collimator is disposed. The distance between the total reflection mirrors and the beam splitter is adjustable.

An optical splitter splits a probe light into two portions and applies one portion to the first arm and the other to the second arm. A first optical coupler combines the probe lights output from the first and second arms. A second optical splitter splits a data light into two portions. A second optical coupler applies one output from the second optical splitter to the first arm in the backward direction. A third optical coupler applies the other output from the second optical splitter to the second arm in the forward direction.
