Therefore, the optical unit 30 branched at the end region of the photoelectric composite cable 100 may be introduced into the rear of the boot 131 of the optical connector without optical reinforcement and may be optically connected. If the optical unit 30 is finished with only the tight buffer coating layer, a separate protective layer addition method for preventing bending of the optical fiber 31 in the end region of the photoelectric composite cable 100 is required, but the optical of the present invention is required. The unit 30 is provided with an optical unit reinforcing material 35 and an optical unit jacket 37 so that the optical connector 30 can be connected to the optical connector without performing a separate operation.
