GPON is TDM (Time Division Multiplexing). The downstream is essentially OC-48 (2.4Gbps). The OLT sets the clock and each ONT has a specific timeslot for uploading. Some vendors can adjust the timeslot reservations to ‘guarantee’ specific upload speeds to specific ONTs From: NANOG on

I’m not mistaken, it also depends on the optics in the splitter, given that GPON is bidirectional single strand fiber. -mel via cell > On Jun 9, 2022, at 5:01 PM, Raymond Burkholder wrote: > >  > >> On 2022-06-09 17:35, Michael Thomas wrote: >> >>> On 6/9/22 4:31 PM, Mel Beckman wrote:

RE: Upstream bandwidth usage

On DOCSIS systems, upload/download ratios are frequency-mapped timeslot ratios that are not adjustable in real-time. On xDSL systems, upload/download ratios are - VERY roughly speaking - a function of how much spectrum is allocated to each direction based on each individual line's

This may sound bad at first but look into FS.com if you're in a pinch. They may not be seen as the typical true enterprise grade (I don't know?) but you can probably buy a a new one and a new spare for the price of one overpriced used switch. From: NANOG On Behalf Of Drew Weaver Sent:
