Optical repeater
First Claim
1. An optical repeater comprising:
- a first optical fiber introduced from an input optical fiber cable for transmitting signal light;
a light amplifying medium operatively connected to said first optical fiber;
a pumping light source for outputting pumping light;
optical coupling means operatively connected to said light amplifying medium and said pumping light source, for introducing said pumping light into said light amplifying medium;
a drive circuit for driving said pumping light source so that said signal light is amplified in said light amplifying medium;
a power circuit operatively connected to a power cable, for supplying electric power to said drive circuit;
a second optical fiber for sending said signal light amplified in said light amplifying medium to an output optical fiber cable;
a common frame defining an inner space wherein for accommodating said light amplifying medium, said pumping light source, and said optical coupling means, said common frame having at an outer periphery thereof a bobbin portion for winding at least one of said first optical fiber and said second optical fiber; and
an individual frame detachably fixed to said common frame, for mounting said drive circuit and said power circuit.

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.
