Under normal circumstances, the colors and arrangement of the four wires of the optical fiber cable plug are: red, white, green and black. Red is the positive pole of power supply, white and green are data transmission lines, and black is the negative pole of grounding. If it doesn't feel normal after connection, please try to change the two data cables in the middle. Black is the ground wire, red is the white wire, and the other two seem to be yellow and green wires (I can't remember clearly! ), which are a pair of differential signal lines. Shenma color line is connected with Shenma color line!

Thread the polished rubber wire into the rubber wire stripper so that one end of the rubber wire reaches the terminal end.

Press the handle of the wire stripper hard, and then pull out the rubber wire, and the exposed solder will be exposed.

Thread the smooth solder into the fixed-length stripper, press the fixed-length stripper and pull out the smooth solder, and then clean the smooth solder with paper.

Press the rubber thread into the tool guide rail so that the skin incision is close to the stop surface of the tool guide rail.

Put the tool path into the groove of the tool so that the tool path is close to the groove surface of the tool.

Press the cutter to cut the smooth solder and take it out of the tool guide rail.

Insert smooth solder into the rubber wire cold connector so that the skin incision is close to the blocking position of the cold connector seat.

Take out the buckle and press the buckle into the rubber wire seat to fix the smooth solder.

Pass another prepared lamp through the other end of the rubber rope seat and fix it with the buckle.

Press the sub-cover of the cold connector, fix the fiber core, and cover the box cover to complete the production of the optical cable connector.
