re: Does Docsis Have a 10-Gig Future?


It seems like there is a lot more room to increase the bandwidth that hybrid fiber coax networks can support. In contrast, I'm hearing that DSL is largely tapped out. 


Telcos will likely need to go to fiber-to-the-home to really compete effectively with cable. But they still seem to have trouble justifying that investment from a revenue perspective outside areas where FTTH is already deployed.


No wonder Verizon Wireless is partnering with the cable companies.

re: Does Docsis Have a 10-Gig Future?


There does appear to be alot of gas in the HFC tank before taking that final FTTP step. For a while it seemed that Docsis and EPoC could grow up together, but it's starting to appear that cable might face a fork in the road at some point. Does it make sense to remake Docsis (4.0?) with their current set of vendors or try to expand further into the Ethernet world and its deeper pool of suppliers by going with EPoC?  It'll make for an interesting technology (and political) debate , but probably too early to say which way it will sway.

It also may not be an either/or situation -- at least not for some years. Fiber-based cable solutions will probably be deployed first where the economics make the most sense, just as we saw with PON, while in other areas network operators will try to work off of existing infrastructure for as long as they can.

Duh!

re: Does Docsis Have a 10-Gig Future?


It will be interesting to see all this play out. Some of these architectures will be more widely deployed than others, some might even be permitted to die.  But I don't expect to see a discrete "fork in the road", for several reasons.   Anybody who's worked with MSOs understands that getting any kind of big picture architecture consensus is like herding cats.  In addition to the tendency of colorful personalities with strong opinions to thrive in MSO corporate cultures, there is too much diversity in the installed base, deployment scenarios, population density, competitive environment and local regulation to get to one solution any time soon.  There can be no doubt that MSOs will pursue the lowest cost solution, but how they perceive the balance of CAPEX and OPEX will vary, along with the many contributing factors to each.   I also would not underestimate the power of relationship sales in keeping the incumbent vendors incumbent.
