Re: coax Ethernet from the node?????? said by patcat88:If your running ethernet over coax for the last mile, why dont they deploy ethernet over coax from a fiber node for the last mile, much higher speeds, less overhead, less D2A, A2A, A2C conversions. The DOCSIS 3 to Coax Ethernet convertor isnt going to be a cheap piece of equipment (its active electronics), and it eats line power, why dont they just do Coax Ethernet to the home stright from the nice fat fiber node? Range and the requirement to add additional equipment to every cabinet on the path from node to customer doing it that way.
Check the Narad Networks products, you'll note that to get the signal through a standard CATV amp it needs to be split off before the CATV amp then recombined with the output of the CATV amp it as it has to work at different frequencies which are outside the range of the CATV amps, which usually tend to max on most plants at 880MHz or less.
Unlikely for there to be room there for the ethernet signal, but enough room for 4 6/8MHz wide QAM carriers, yep, sure. |
