Optical cable structure for efficient test instrument

An optical cable structure for a high-efficiency test instrument relates to the technical field of optical cable test equipment. Comprising five units including three test optical cable units and two bare fiber units, the test optical cable units are finished single-mode jumpers with customizable lengths, each bare fiber unit comprises two parts, and the connection sequence is that the two parts are sequentially connected and fixed by using a welding machine from left to right according to the sequence. The bare fiber unit is connected with the test optical cable unit through optical fibers, an installation part is fixedly installed in the middle of the interior of the cable cavity, two optical fiber channels are formed in the upper end of the interior of the test optical cable unit, a limiting rod is fixedly connected to the middle of the side, facing the installation part, of the arc plate, and a limiting groove is formed in the position, corresponding to the limiting rod, in the installation part.
