ONT Fibre Stats for CommunityFibre?

Hi All,

I was wondering if anyone knows how to get onto the ONT and have a look at statistics for fibre connections? Light levels etc

I have CommunityFibre’s 3gbps service only got it wednesday.

I’ve got the Adtran SDX-621X.

Cheers

Hey,

Simple answer is you can't.

The light levels have a pretty wide range and hopefully were tested and are okay. Community Fibre can query your ONU if there are any concerns but FTTP is a stats-free zone as a general rule.

Once you've FTTP issues are far more likely to show on other parts of the connection than the fibre: it won't degrade for decades. On XGSPON issues are more likely on upstream than downstream and those are seen at the OLT, not your ONU.

Light levels could be taken with a relatively inexpensive power meter, however as XGS_Is_On has said the other stats really aren’t visible to users. It really boils down to “enough” light and the “right” light - all of which the LED indicators on the ONT will tell you.

Thanks Both!

I thought that would be the case but thought I’d ask anyway.
When talking to their support apparently they’re working on a portal to see these kinds of information, I wont hold my breath to see that though lol

Cheers,

I can't see any benefit to a provider exposing the PON power levels to subscribers, it would only cause support tickets to be opened by people who aren't having any issues at all but think they know what their power levels should be.

It’s handy for the techies that know what they’re looking at.
I am interested in seeing the light tx/rx levels, snr etc, handy too keep a snapshot of what was there on install and comparing these later down the line when an issue might arise.

Just FYI there's no SNR / SNR margin shown on GPON/XGSPON connections as they are digital. Without demodulating an analogue signal the kit can't know how close it is to the ideal signal quality and without bit errors it can't know if the quality is inadequate.

There really isn't much to see and unless things break there won't be changes to what you can see: in which case there's absolutely nothing you can do about it and you'll have to call the ISP who'll see the problem anyway: PON works or it doesn't with a tiny grey area where it intermittently works. It can't fall back to a lower speed to adapt to conditions so broken or not is about it.

As @XGS_Is_On says the classic items you'd look at on xDSL are largely irrelevant for PON networks and no real use to the end user. For the PON provider light level can be useful, but looking more at things like is the level deteriorating, how does your light level compare to others around you. There are also different optics types which work to different light levels that applies to both ends of the PON.

There is also lots of other data on a PON from the OLTs and ONTs that can help the provider see how things are performing but they are very different to xDSL.

I don't know what monitoring CommunityFibre do, but I know others that do monitor lots of data from the OLTs and ONTs to know how each customer is performing, they can also get data on ONT reachability, is your router plugged in, potentially PPP or DHCP status info to know if your link is working.
