What Does Pon Light Mean

If the “passive optical network” (PON) light is solid green and the “loss of service” (LOS) light is off, then it’s working properly. This means you’ll need to contact the company you buy your broadband from as there may be a problem with their network.

What do you do if your PON light comes on?

  1. Switch off your modem for 5 minutes then switch it back on.
  2. Check the condition of the fiber patch cord for any break, bend or damage.
  3. Ensure that both ends of the fiber patch cord is inserted correctly.

What does it mean when PON light is off?

Openreach optical network terminator PON light is off, LOS or optical light is red. Broadband isn’t working. Check that your fibre cable is firmly plugged in and isn’t damaged.
