Monitoring Optical Transmission Media and Characteristics Analysis
2020-05-28 15:12:50
With the development of the times and the increasing requirements of users for security precautions, surveillance optical transceivers have been increasingly used in the security field, and the technology for monitoring optical transceivers has become more and more mature, so the current monitoring optical transceivers can already be realized in one core. Multiple signals such as video, audio, data, telephone, Ethernet, and alarm are transmitted on the optical fiber.
First, monitoring the optical transmission medium and its characteristics
The medium used to monitor the optical transceiver is optical fiber. So why choose to transmit it through optical fiber? The main component of the optical fiber is silicon dioxide (SiO2), which accounts for a large proportion of the minerals in the entire earth, usually In stone, sand can be extracted. Fibers made of silicon dioxide (SiO2) are brittle as glass and fine as hair. From its internal composition, optical fibers are classified into single-mode fibers and multi-mode fibers. The core diameter of single-mode fibers is 9 μm, and the core diameter of multi-mode fibers can be divided into 50 μm and 62.5 μm. Due to the composition of the optical fiber, it has the characteristics of long transmission distance, non-conductivity, strong anti-interference ability, good confidentiality, etc. It is usually the first choice of the majority of engineering companies in long-distance transmission.
Second, the optical fiber transmission system needs debugging, testing equipment
1, optical welding. It is mainly through the electrode, in the case of an instantaneous discharge, the optical fiber and the optical jumper welding together, in the welding, it should pay attention to the end of the optical fiber to be neatly cut, and to maintain the clean end.
2, OTDR optical time domain reflectometer. This is a testing instrument that mainly detects whether there is a fiber break during fiber transmission.
3, the optical power meter literally, it is a power measuring instrument, but it does not measure the voltage power, but the power of the optical fiber transmission, and the attenuation of light in the transmission process.
Third, monitor the application of optical transceiver
With the ever-increasing social security requirements, surveillance optical transceivers have been widely used in monitoring systems in various industries such as smart communities, factories and mines, urban security, banking networks, road traffic bays, electronics* and highway toll collection. . It guarantees the real-time and security of the transmission, and has a large transmission capacity. It not only transmits video, but also transmits audio, data, telephone and Ethernet at the same time, which is respected by people.
