Re: Interesting... said by etaadmin:There are some interesting proposals that want to bond all channels in a HFC plant and make it a big fat pipe.
Maybe but how much is it going to cost? Remember the economics of coax really only works with existing cable plants. The outdoor coax really should be replaced after about 15 years. At some point it will make more economic sense to go with fiber optics just like when tractors replaced plow-horses. |

Actually, the cost is negligible compared to what deploying fiber costs. I agree that fiber is the future and a very elegant solution but the life left in HFC systems is... I would say 15, 20 or more years?
Our neighborhood's 860 MHz HFC plant is older that 15 years and we have no problems, when we got docsis3.0 all that the cableco had to do is to issue new modems. I never saw a cableco truck working on anything outside our neighborhood, all work was done on the CMTS and replacing modems. |

What makes you think coax needs to be replaced after 15 years ? I know places where coax is at least 50 years old and still going strong. Coax is usually replaced because its upgraded in size not because it goes bad. |
