seem know one can tell me this then...
Wasn't aware there was an SLA on forum responses.
I was just wondering if anyone has any information that would tell me how much bandwidth up and down is available on each node that serves a loop of cabinet
Depends how much VM have provisioned to that node.
and also a refresh on how many cabs are normally served by a node.
Amount of cabs irrelevant as they come in different sizes and some areas don't have cabinets at all.
Homes passed the target is somewhere between 250 and 500 homes, however as I'm sure you're very much aware an individual node may be combined with another node or more than another node so bandwidth is spread between them, and there may be more bandwidth available than an individual modem can access due to the configurations in use.
A single modem may have access to 2 of 4 DOCSIS 3 upstreams due to configuration and there will be some DOCSIS 1.1 upstreams there too. There could also be 6 - 12 downstreams present of which a single modem can lock onto 8, max.
The upstreams may vary in modulation from 16QAM to 32QAM to 64QAM, and the DOCSIS 1.1 channels 1.6MHz or 3.2MHz, which makes a 50% difference in bandwidth available on modulation and 100% in channel width.
