There is no light inside the optical cable

No light on an optical cable usually indicates a broken cable, blocked connector, or incorrect device settings.Check Physical ConnectionsEnsure both ends of the optical cable are fully inserted into the correct ports on your devices. Optical cables use square TOSLINK connectors, and even a slight misalignment can prevent light transmission. Remove any protective caps on the cable tips, as these can block the light signal if left in place. Inspect the cable for visible damage such as bends, frays, or cracks, which can break the fiber core and stop light from passing through .Inspect the Cable LightMost optical cables transmit a red light at the connector. To test:Disconnect one end from the receiving device.Power on the transmitting device.Look at the exposed end; a bright red light indicates the cable is functioning, while no light suggests the cable is broken or the device is not outputting a signal .Verify Device SettingsOptical cables require the correct audio or data output mode:On TVs or audio devices, navigate to Sound or Audio Settings.Ensure the output is set to Optical/Digital Out and not the internal speakers.Select the appropriate audio format, such as PCM, if required by your system .Restart the devices after changing settings to refresh the connection .Test with Another Cable or DeviceIf possible, try a different optical cable or connect the cable to another compatible device. This helps determine whether the issue is with the cable itself or the device ports .Replace Damaged CablesFiber optic cables are fragile; sharp bends or physical stress can snap the core, permanently stopping light transmission. If the cable shows signs of damage or fails the light test, it should be replaced . By systematically checking connections, device settings, and the cable itself, you can identify the cause of no light on the optical cable and restore proper signal transmission.
