[ Huaqiang Security Network News ] Optical path problem of optical transceiver : In the security monitoring project, most of the optical cable is laid by the user, usually G652 single-mode fiber. Since the coverage of the system is generally small, the optical link loss of the device is very rich with the standard (≤20KM). Therefore, the optical transceiver does not have excessive requirements for optical path loss, but users often encounter no image, image jitter, and image quality. Problems such as poor, when most of the problems are on the pigtails, jumpers or adapters at both ends of the light path, and rarely related to the trunk light path. 
Common problems are:
1. The fiber optic active connector is inserted incorrectly;
2. The fiber optic active connector core (ceramic tube) is contaminated.
The solution is:
1. Reinsert the active connector or swap the fiber jumper;
2. Wipe the plug with 99.9% absolute ethanol and the core of the socket;
3. Check the camera video cable with a multimeter to determine if there is any video signal.
