With the gradual deepening of applications in the field of optical communications, national communications manufacturers have gradually begun to independently develop fiber optic repeater products. The emergence of domestic repeaters has greatly reduced the average cost of the fiber optic repeater. At this time, single-mode fiber optic cables and fiber optic repeater have gradually matured, making the transmission distance longer and the effect better, and have been applied in more monitoring fields. So, how to install and debug the fiber optic repeater?
When installing the fiber optic repeater, you must take good on-site protective measures to prevent moisture, water, and dust. At the same time, pay attention to the actual operation of the site. You should select suitable fiber optics for use. Incomplete and faulty fiber optics cannot be used. If they are not matched, it will seriously affect the transmission quality of optical communications repeater. When it comes to optical cable fusion, attention should be paid to measuring the optical attenuation or loss of the optical cable within the effective value range.
The debugging of the fiber optic repeater mainly refers to the debugging of the fiber optic and the data channel. Since there are many types of fiber optic repeater data available, according to the actual needs of the site, the data types of the fiber optic repeater used on the site are also different. When debugging, you must refer to the corresponding manual and carry out data wiring according to the data dial and interface definition in the manual.
The on-site installation environment of fiber optic repeater is complicated. Some users usually suspect that the product is faulty when the debugging fails. In fact, the product technology of fiber optic repeater is very mature. The product has been repeatedly tested and copied before leaving the factory, so it is less likely that it is the problem of the product itself. Therefore, when there is a problem at the scene, the first thing to consider is the installation problem, which can be checked from the following aspects.
1. The fiber optic itself has not been tested, the optical path is blocked or unstable, or the optical attenuation is too large.
2. Front-end equipment failure, such as no video or no power on the camera.
3. The back-end equipment fails, such as the monitor has no video, the keyboard control protocol is incorrect, and it cannot be controlled by itself.
4. The connection line is faulty, such as the video head welding failure, the control line is connected incorrectly, or the connection line is cross-connected wrongly or reversely, etc.
The above phenomena, especially the line fault, are most likely to happen, and you need to check carefully when you encounter a problem. When debugging, you can use the elimination method. That means you can check the device one by one, and finally accurately determine the key to the problem. When judging whether there is a problem with the fiber optic repeater, it is recommended that the user put the transmitter and receiver together for a close test. If it still fails, the fiber optic repeater itself is faulty, and you need to contact the manufacturer for replacement. In order to reduce problems, users would better test the fiber optic repeaters before installation at a close distance, so that they can quickly pass the installation and debugging process and save the construction period.
