What robot model and controller type?

Replace the fiber-cable.
Although it may look ok, it is pretty fragile and may be internaly damaged.

I would say examine the servo amp LEDs when this occurs I doubt it's the fiber cable but the fssb is the connection from server amp to access control card on the main board. You can also unhook this fiber cable and you will see a red light emitting from one side and and on the other end of the connection that red light on the opposite side.

fanuc RJ-3 M16i , I have replaced the optic cable multiple times.

This is a common problem with the Fanuc RJ-3.
You need to replace the Back Plane PCB. -
Mike, why do you think is the PCB backplane and what exactly is that?
-
As I said this is a common problem with the RJ-3 model.
The difficulty in diagnosing is that the problem is intermittent, when you inspect the fiber optic lights they are both on.
If you were to unplug the fiber connector and one of the light sources was off you would be able to troubleshoot that source and then repair it.
The back plane PCB is the printed circuit board on the back of the yellow back plane where the CPU card and power supply are mounted.
When I was a service engineer for Fanuc this was what fixed these intermittent problems.
