Causes and solutions of red light in optical signal

The red light of the router's optical signal indicates that this device is not a router, but a PON device that combines an optical cat and a router. That is, the popular light cat at present. When the signal light is red, there are the following situations:

Optical interface problem of optical cat

There is something wrong with the optical interface of the light cat, which needs to be replaced. This situation is rare.

Indoor pigtail connection problem

The indoor tail fiber connection optical cat connector is loose. Plug in the connector and it will be restored.

Excessive bending of indoor optical fiber

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.

Outdoor optical fiber breakage

Some outdoor optical fibers are broken and need to be handled by operators.

Equipment failure in operator room

The optical port of the equipment in the operator's computer room is faulty, which needs to be handled by the operator.
