  • The optical module is still showing a red light even though it s emitting light

    The optical module is still showing a red light even though it s emitting light

    The solution is to unplug the fiber and reinsert it into the SFP module interface until a “click” sound is heard, indicating the fiber connector and SFP module are properly connected. Contamination or damage on the fiber end face requires the use of a fiber end-face inspection. The checking includes, but is not limited to, the following three aspects: 1. Basic checking: LED status; the suitable fiber/Ethernet cable; the wavelength and the mode (multi/single); the speed, etc. Among various after-sales issues, the "optical signal indicator light staying red" is a relatively common problem, and we will provide a detailed explanation for you today. These faults can affect network stability and, in severe cases, cause network interruptions, resulting in losses. A green light typically means the module is working fine, while a red or amber light might signal a fault.
