The network cable with power

The network cable with power supply actually uses the remaining network cable as the power supply line. The network cable actually uses four wires, and the remaining four wires can be divided into two groups as the positive and negative wiring of the power supply. This is POE power supply. 1. If it is connected to the monitoring network cable and needs to be powered, their wiring methods are similar. First of all, we need to use wire dial pliers to strip the network cable for a certain distance. Generally speaking, a core of about 2 cm should be exposed. 2. You will see that there are 8 copper wires corresponding to different colors. You need to straighten the copper wires, and then arrange all the copper wires in order. 3. The next step is to cut the 8 copper wires evenly, leaving a length of 1.5 cm. The incision should be very smooth, and there should be no looseness when cutting. 4. Next, take the crystal head and embed 8 copper wires inside, push it to the innermost end, and then clamp it with wire crimping pliers. 5. Finally, we use a network cable to connect the monitoring to the monitoring room with an optical fiber. After connecting to the same main line, the computer can be connected in place.
