Abstract

The utility model relates to a light attenuation jig of a photoelectric hybrid cable, which comprises an optical fiber connector, light attenuation and an SC-SC optical fiber jumper wire which are arranged in sequence, and the optical fiber connector is in circuit connection with the SC-SC optical fiber jumper wire through a cable. With the adoption of the light attenuation jig of the photoelectric hybrid cable, the problems that when a home gateway product with the photoelectric hybrid cable as a power supply and communication mode is tested, power cannot be supplied and the power supply reliability of a photoelectric hybrid interface cannot be verified due to the fact that existing single-structure light attenuation and jumper wires are connected are solved. Therefore, the testing safety is improved, and the situation that equipment only provided with the photoelectric hybrid cable needs to be manually connected with a power supply from a board end for power supply testing is avoided, so that the testing efficiency is effectively improved.
