Due to the complex installation environment of the optical transceivers, some users usually suspect that the products are faulty. In fact, the technology of the optical transceivers is very mature. After the products are shipped out of the factory, they have undergone repeated testing and copying, so the product itself is less likely to have problems. Therefore, when there are problems in the field, the first thing to consider is the installation problem, which can be investigated from the following aspects:
1. The optical fiber itself has not been tested, the optical path is not stable or the light attenuation is too large, etc.;
2. The front-end equipment is faulty, such as the camera has no video or no power;
3. Back-end equipment failures, such as no video on the monitor, incorrect keyboard control protocol, and the inability to control itself;
4. The connection line is faulty, such as the welding of the video head is not good, the control line is connected incorrectly, or the connection line is connected wrongly or reversed.
The above phenomenon is especially the most likely to occur when a circuit fault occurs. When a problem is encountered, it needs to be carefully checked. When troubleshooting, you can use the elimination method to eliminate one device and one device, and finally determine the key to the problem. When judging whether there is a problem with the optical transceiver, it is recommended that the user put the transmitter and receiver together for close-range testing. If the connection fails, the optical transceiver itself is faulty, and it is necessary to contact the manufacturer for replacement. In order to reduce the problem, the user should test the optical transceiver at a short distance before installation, so that it can quickly pass through the installation and debugging, saving time.
The debugging of optical transceivers is mainly the debugging of optical fibers and data channels. Because there are many optional types of optical transceiver data, depending on the actual needs of the site, the type of optical transceiver used in the field is not the same. When debugging, it is necessary to refer to the corresponding manual, according to the data dialing and interface definition on the manual. Data wiring.
