4th Generation ONT Introduction


The ongoing supply of the current 3rd Gen ONT has been impacted by challenges arising from the global chip shortage. The 4th Gen ONT will be used as a like-for-like replacement as 3rd Gen ONT stocks are depleted.

The new 4th Gen ONT is identical in functionality to the current 3rd Gen ONT, and provides some additional benefits, including improved Wi-Fi range (when in RGW mode) and the potential to support Bitstream 3 offers in future (further software development will be required to enable this). This ONT has strong uptake in international markets, which indicates strong assurance of ongoing supply and production performance.

Timeline and next steps

The rollout of this new ONT will begin as techs run out of stocks of 3rd Gen ONTs. We have managed to secure one more shipment of these, which has pushed this date out. Large scale deployment is expected to begin in calendar Q4 2022, depending on the ONT consumption through to that point.

Test plans for the new ONT have been shared through the TCF Forum. RSP Workshops were held in October/November and test ONTs will be sent out to RSPs when the stock and final version of the software have arrived.
