The video fiber mux is a device that converts video signals to light. It is a transmission device. It is widely used and very important. Therefore, there are many precautions in daily use. Let’s take a look at what the precautions are. matter.
The ground grid is well grounded, and the grounding resistance is preferably less than 1 ohm
The power supply, video signal cable, and control data line need to be installed with lightning arresters. Special emphasis is placed on the grounding of the lightning arrester of each video signal line, data control line and power supply. Use 10 square grounding wires respectively, and solder copper on the grounding wires. nose, and then crimped separately on the ground flat bar. Take the reverse data of 8 channels of video as an example: 10 ground wires of 10 square meters are required (1 for data, 1 for power supply, and 8 for 8-channel video, a total of 10). Note that these 10 lightning protection ground wires cannot be connected to the same point of the ground grid flat steel, and the two adjacent grounding points should preferably be separated by more than 20 cm.
Wear a dust cap when the optical fiber interface is not used for a long time. In order to prevent dust from entering and affecting the transmission of light
During the installation process, attention should be paid to the installation specifications, and the signal wire and the power wire should be separated. Do not put the power cord (especially AC220V) on the control signal line and the DC power supply line of the optical transceiver by mistake, which will cause damage to the equipment.
The front-end machine should pay attention to waterproofing during use.
The above are the precautions when using the video fiber mux, I hope it can help you, so that you can use it better.
