A fibre-optic outage often brings an entire business to a halt: no Internet, no telephony, no access to online tools. Before panicking, a few simple checks can save precious time.
The most common causes
- Carrier outage on the external network (works, incident).
- Faulty equipment: box, router or ONT (optical unit) out of service.
- Connectors: optical patch cord unplugged, dirty or pinched.
- Damaged cable during works on the premises.
First reflexes (before the intervention)
- Check the ONT/box indicators: a red or off optical light often indicates a loss of signal.
- Restart the equipment (ONT, router) once, cleanly.
- Check that the optical cables are properly connected and not pinched.
- Determine whether the outage is general (several sites/neighbours) or local to your premises.
Never pull on a fibre cable and never look at the end of a live fibre: the laser is invisible and dangerous to the eyes.
When to call a technician
If the optical signal is absent on the business side, if the connectors are damaged or if the outage persists after these checks, a fibre technician is needed. With the right measuring equipment (OTDR reflectometer), the break is located and the service restored quickly.
Plan ahead to limit the impact
- Keep the reference of your link and the carrier contact at hand.
- Provide a backup solution (4G/5G) for critical services.
- Document your setup (patching plan, labelling).
