Just a general question about UPS/backup for ONTs - I've had a few customers who have a UPS but the other end doesn't seem to in the event of a widespread power outage - this is from when the power outage starts. Is this normal? Or should it be expected that the network end have some backup supply as well, at least for a few hours? Areas are Northpower and Chorus
UFB fibre is run on GPON - gigabyte passive optical network. The passive means that the network in the street does not need power. As long as the exchange building has power, then the network will continue to run. All exchanges have back up power with redundancy in place so there's no technical explanation for what you are reporting.
The only explanation I can think of is where there is a fibre cable cut in tandem with a power outage - but the driver of no service in that scenario is the cable cut, not the power being out (if an ONT/router UPS exists).
