Tracing backwards, upstream from your Narad link, I came to the following links, which I offer for those who may not have seen them yet:

Both the Narad and Actelis models are interesting in that they each enable the provider - through a new adapation of some existing technologies, albeit modified - to get somewhere with greater bandwidth than they were able to accomplish before, in each case using older, embedded infrastructure.
But in each case (the MSOs and the ILECs) it's not quite clear what the new service architecture would look like. Easy enough to say transparent LANs, but how does the t-LAN play into other issues such as open access for other ISPs, allocation of resources on a per customer basis, given the limitations at the aggregate speeds cited, and so on.
It will be interesting to pursue this further. Historically, when an MSO (e.g., Adelphia and Cablevision) wanted to serve a business client off-net (off the regular cable tv framework), they would simply extend fiber to the customer, or reuse an ILEC facility. Some have even leased and resold dsl lines, a la @work.
The earliest case that I recall when an MSO extended an appreciable data service to the general public (not counting Manhattan Cable's <now TWX> emulated circuit-switched broadband data services of the Eighties) was Continental Cable in Boston, when they created their 10 Mb/s cable system Ethernet over discreet fiber strands intended only for that purpose, circa 1996, which served the same purpose. |
