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.

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.
