The 4G network signal is very poor, and the slim cat is always red.

Hello, if the LOS light on the light cat turns red or flashes, it is usually caused by the following situations:

1 There is something wrong with the optical interface of the optical cat, which needs to be replaced;

2. The indoor pigtails are connected with optical cat connectors, which can be restored after being plugged in;

3. Some indoor optical fibers are too bent. Excessive bending of optical fiber will affect the total reflection transmission of optical signals in optical fiber, as long as the optical fiber is straightened;

4. Some outdoor optical fibers are broken or the optical port of equipment in the computer room is faulty, so it is necessary to contact Unicom staff to eliminate the fault.

1. Our company has always attached great importance to the construction of 4G networks, continuously invested funds to increase the construction scale of 4G networks every year, and set up a special optimization team to improve the network quality. At present, our 4G network has covered most provinces and cities in China.

2. Due to the rapid development of the city and the ever-changing communication network environment, some emerging buildings and places need time to implement security. The dense houses and high-rise buildings in the city will have a certain impact on signal coverage. In addition, due to the need for property assistance in base station construction, network construction in some areas still has certain restrictions, and 4G networks in some locations and indoors may be slightly weak. Our company is stepping up efforts to improve network coverage.
