ABSTRACT:
An optical repeater having a first optical fiber extending from an input optical fiber cable, a light amplifying medium connected to the first optical fiber, a pumping light source for outputting pumping light, an optical coupling module for introducing the pumping light into the light amplifying medium, a drive circuit for driving the pumping light source, a power circuit for supplying electric power to the drive circuit, and a second optical fiber for sending signal light amplified. The optical repeater has a general-purpose common frame. The common frame has an inner space defined so as to accommodate the pumping light source and the optical coupling module, and has a bobbin portion for winding at least one of the first optical fiber and the second optical fiber. The drive circuit and the power circuit sometimes differing according to the kinds of products are mounted on an individual frame detachably fixed to the common frame. The optical repeater is suitable for a reduction in size, has good heat radiation, and is suitable for flexible manufacturing.
