Red PON light

[Gladrags2225]

New installation of full fibre broadband today. Worked for one hour. Then solid red PON light on Openreach box and no broadband. All sky checks say everything is fine. Please help.

@Gladrags2225  Are you just running the service checker or are you clicking also on the broadband button to run a updated test?

Thanks Highlinder

spoken to sky, and apparently red PON light is an Openreach issue. Fingers crossed they'll fix it tomorrow with an engineer visit.

Red PON light means there is a break in the optical fibre cable.

In my case, in the outside grey box, the splice between the internal and external fibre optic cables had separated and hence the problem. Was a 5 minute fix for the open reach engineer. Tho he did need a specialist splicing machine.

Hi how do I report the Pon light? Is it through sky or openreach?

[Gladrags2225]

I reported a technical problem thru sky. Engineer came next day. Phoned sky, not sure which number.

Brand new service should have gone active yesterday but red light on router despite rebooting etc. Sky said they checked the line before we proceeded with the contract. My own check says all is well but it obviously isn't. You refer to two checks. What are they and what's the difference please?

@Primescape if you have full fibre then check the ONT  unit on the wall this thread discusses the issue with a LOS red light on that which means the fibre network is nit working. This can happen after an ibstall if the weld done by thecengineer with the external fibre cable fails. Call Sky are report the issue. 

Red light in the hub also indicates the hub has lost connection again unless the service checker in the My Sky app run over a mobile connection reports that Sky arexaware of the fault call them to report it.
