摘要： An optical fiber terminal fitted with an optical isolator in close proximity in a unitary structure comprises an optical fiber, a ferrule which holds the optical fiber in position, at least one magneto-optical element located as aligned with the optical fiber, and a cylindrical permanent magnet that applies a magnetic field to the magneto-optical element. The magneto-optical element is disposed axially outside of the magnet, and the end face of the optical fiber is located in the hollow of the magnet or in the space between the magnet and the magneto-optical element, so that the overall outside diameter and length can be decreased. The ferrule, made of a soft magnetic material, increases the magnetic field strength of the magnet.

摘要： The optical module includes a main housing to which the optical fiber can be attached and a light-emitting component and a light-receiving component attached to the main housing. At least a part of a surface of the main housing has an irregular pattern to enhance a thermal dissipation. Because at least part of the main housing comprises a heat sink, so the optical module itself has a very high heat dissipation property, eliminating the type of problems that arise when adhesive or the like is used to attach to the main housing heat sinks constituted as separate parts, such as the increase in the number of parts and the degradation in thermal conductivity to the heat sink caused by the adhesive.
