Video optical transmitter is a device that converts 1 to multi-channel analog video signals into optical signals through various codes and transmits them through optical fiber medium. Its principle is to modulate the signals to light and then transmit video through optical fiber. So, do you have an in-depth understanding of the installation method and precautions for the use of video optical transceiver?
The installation method and precautions of video optical transceiver are introduced
I. Installation method of video optical transceiver
1, open the equipment packaging, first check the appearance of the equipment, there should be no damage and abnormal noise.
2. Connect the power supply:
A. Plug the AC power cord in the packing box into the power input port of the optical transmitter and optical receiver (AC220V).
B. The green indicator light of POW and the red indicator light of NOP and LOS of the optical transmitter indicate that the optical transmitter works normally; The yellow indicator light of POW and red indicator light of NOP and LOS indicate that the optical receiver works normally.
C. Power off after system self-check.
3. Connect the optical fiber: connect the FC/PC jumper to the optical output port of the optical transmitter and the optical input port of the optical receiver respectively, or connect the optical transmitter and optical receiver directly with the jumper for short distance test.
4. The field image signal is received from the video input port of the optical transmitter, and the video signal output from the corresponding video port of the optical receiver is transmitted to the monitor and other equipment by coaxial video cable. Connect the data line to the data port of optical receiver and optical transmitter respectively. Pin definition is: "485+" connects to data end A, "485-" connects to data end B, and "GND" does not connect.
5. Turn on the power:
A. If the NOP red indicator light of optical transmitter and optical receiver is off, it means that effective optical signals are received. If the LOS red indicator light is off, it means that optical signals are synchronized and the optical signals are correctly connected. B. When there is video transmission, the video signal indicator light corresponding to the optical transmitter and optical receiver lights up, and the image can be monitored and recorded.
Two, the use of video optical transceiver notes
1, the electrical and mechanical power input of optical terminal is AC220V power supply, please use the special power cord provided in the equipment package. The voltage range of the power supply is AC125V ~ 250V. Do not use it beyond the range. Ensure continuous power supply during use.
2. Both optical transmitter and optical receiver are indoor models, and the operating temperature and humidity should be within the range of equipment operating parameters; Otherwise, the equipment may be damaged. In the use of the optical end machine, it is necessary to maintain a ventilation, heat dissipation, moisture-proof and clean working environment.
3. When the optical transmitting and receiving devices are not connected to the tail fiber connector, please seal them with protective caps to avoid dust entering and affecting the transmission of optical signals.
