There are several reasons why the light cat los flashes red light.
Four things that users can check by themselves:
1. A bug in the Optical Mode firmware causes its los to flash red. Disconnect the optical modem's power plug and plug it back in to restart the optical modem. If its los light is off, it means that the received optical signal is normal, and you can resume Internet access.
2. The small square fiber connector connecting the optical modem is stained, resulting in poor contact. Wipe it clean with alcohol and reinsert the fiber optic connector.
3. The optical fiber in the indoor entry box is bent. Gently re-straighten it by hand so that the turning radius of the fiber is no less than 5 cm. If the turning radius of the optical fiber is too small, the optical signal will be seriously attenuated, making it impossible to access the Internet. If there are no naughty children at home, this problem will rarely occur. Because the installation master of the communication company will handle it properly when installing broadband for the first time.
4. The light cat was damaged due to quality problems or overdue operation. Nowadays, the communication company's optical modem has a 2-year warranty. If the optical modem breaks within 2 years, it will only be replaced but not repaired. Under normal circumstances, there is no problem if the light cat is used for 4 years. If it is an old cat, the red light will flash when los appears. You can borrow a neighbor's good light cat to replace the old light cat to see if the light cat is broken. If there is no replacement optical modem, call the customer service of the communication company and ask an installer to use professional equipment to check the specific problem.
Problems that only the installation master can troubleshoot:
1. The optical fiber from the outdoor optical splitter to the indoor is broken or the optical signal is severely attenuated. The installer can detect this with a light meter.
2. If the optical fiber connector is broken, use a cold fusion machine to reconnect the optical fiber connector.
Summary:
The red light of the optical modem los flashes, indicating that there is a problem with the optical signal reception of the optical modem and it cannot access the Internet. Either there is a problem with the optical fiber, or there is a problem with the optical cat.
