Singnet Fibre - Red LED for LOS?

[Dr_ARCHer]

Around 4pm yesterday, the internet for my Singnet fibre suddenly went down. The LOS LED on the ONT is showing red, and no other LED is lit up other than the POWER LED, which is green.

Does anyone know what this mean? Is it an equipment problem e.g. the ONT not working? Or is it a fibre problem? SingNet engineer seems to suggest that it is an OpenNet issue as this means there is no fibre signal.

did you try to restart the ONT?

Did you check if the patch cable is inserted properly?

 

[Dr_ARCHer]

All checked. I even try with spare optical cables.

Today your fibre still down? Which area your fibre service? later I go home I check my fibre. Yesterday was ok for me

 

[Dr_ARCHer]

Joo Chiat area. Actually, the one that is down is my parent's place. My own place is also in Joo Chiat area, but I have no problem with either Singnet or ViewQwest. My parents place is using Singnet.

LOS light is normally opennet issue. Possible that they have accidentally pulled out your fiber cable, or someone have damaged it.

Which ONT?

Too bad ZTE one, cannot measure power value, so no indication on whether if its dark.

 

[Dr_ARCHer]

The black one, not the white one. The LOS light is solid red. The PON light is off.

no problem with my internet fibre

LOS LED on the ZTE ONT indicates no signal/GPON unable to sync.

Probably either the nearby CAB end some contractor did patching/cabling work that might have damaged your port/patch cable.

Thanks guys. I called up SingTel, and SingTel contacted OpenNet. OpenNet is coming down tomorrow.

Funny thing is, this afternoon, the Internet came back on.

Previously, I had ADSL and always get disconnected. At least, the router could reconnect again. Switching to router, I thought it would be a lot more reliable. Hopefully, this is just a once off type of problem.

I haven't cancelled the OpenNet appointment yet. I am hoping that they can come down and have a look and tell me what is the problem.
