Abstract

See full text

The present invention provides an optical isolator module, including: a plurality of optical devices, each comprising a Faraday rotator and being configured to have an optical isolator function upon application of a magnetic field, a magnet to apply the magnetic field to the Faraday rotator in each of the plurality of optical devices, wherein at least two optical devices of the plurality of optical devices are configured to have the optical isolator functions in different directions from each other, and each magnetic field applied with the magnet is in the same direction. This provides an optical isolator module that can be prevented from degradation of the performance such as increase of insertion loss and degradation of isolation due to magnetic field interference even when a plurality of optical isolators are close to each other.
