| actually Time Warner is partially correct
Actually Time Warner is partially correct in their supposed statement that they (probably supposed to mean the "Cable Operators" in general) have been using fiber optics before Verizon. This pertains to TV service. Cable providers like Comcast and Time Warner Cable use Hybrid-Fiber-Coax networks, which start out from the headend using Fiber lines to the nodes, which converts the fiber line (and signal) to coax.
Now although I haven't seen this yet, Time Warner claiming you need a dish is false, I don't know where they got that from. But you do need a cable-box on every TV that you want to have cable channels, since they are all digital. Cable operators are struggling to catch up to the other all-digital cable system/networks (ex. Fios, DirecTV) primarily because they still have analog channels and plenty of analog-only customers. 12 Digital channels or 3 HD channels can replace 1 single analog channel. So, they will migrate digital channels over to analog, but that takes some time too.. They are going to gradually migrate selected channels over to digital, but customers with analog sets are going to call complaining that we took their channels away and claim murder as usual. Change is good though, and hopefully these folks will migrate with everyone else and eventually just get the cable boxes. Change is going to happen anyways whether they like it or not.

Verizon used fiber for the backhaul and remote systems before they even were Verizon. HFC is topologically not much different than any FTTN set-up. |

When verizon was still bell atlantic here on long island they were going to convert the long island network to all fiber in the late 90's. They started the conversion in the 90's and then stopped when they went to verizon .
The telcos have had fiber before the cablecompanies . |

Sorry for not making this clear, I meant to state that Timew Warner probably is refering to how long Cable Operators have been using Fiber for TV. TV afterall is what Cable Operators started out as. So I think thats what they mean. But Time Warner isn't the only company stating this. Comcast has been too. |

Comcast and Time Warner DID NOT start out with Fiber. They added it in the mid-late 1990s. Remember when you had to call in by phone to get PPV? Telcos used fiber way before cable TV did. |

Telcos used fiber way before cable TV did. WHAT!? PPV had nothing to do with it! Cable system is Hybrid-Fiber-Coax also dubbed HFC. The boxes upgraded to digital and 2way technology, enabling the use of PPV with your remote. But that has nothing to do with the system which has been in place using FIBER to the Node which is converted to trunk cables which are coax. Thats why its called Hybrid Fiber-Coax... HFC was out before mid-1990's. |

ummm, it was the fiber that replaced the coax trunks from the headend to the cascades.
this didn't happen that long ago. i know, i was there.
coax leaving the node is not referred to as trunk. |

I work on transport equipment for Verizon-- they were placing and using fiber way before cable. I run into mid-to early eighty's fiber in the network all the time. If my memory is correct the first fiber was placed into service in 1977 in Illinois Bell territory (Might be mixing up with some other first on the location.) Some other firsts way before cable that cable is built on. Multiplexing- ATT was doing analog multiplexing between CO's in 1919. Digital transmission-- Bell Labs had working T1 prototypes in 1954. First out side digital carrier systems were deployed in 1964. And... ATT/Bell Labs invented coax in 1929 and I believe ATT's first coax T3 Ran from Baltimore to Denver. Might be off on a few dates above but the fact is still the same. Data transmission over distance history is Bell/ATT/Bell Labs.
I have posted this before Verizon has more fiber in West Virginia than any cable company has in it's entire network. |

it was one way but still on hybrid fiber coax
the new technology came out with new devices, people still use 1way analog cable boxes. there is no use for them but some people still have them because they don't like the new stuff - primarily older people like the elderly. when they came out with 2 way technology with the cable boxes and the head end servers and some node enhancements it became 2way aka broadband. |

In regards to fiber being there first, its sketchy and haphazard, but fiber was laid for "trunk lines" (tongue in cheek here) twenty years ago easily.
When the groundwork was laid, most of the major telco's put out alot and either leased it out or let it stay dark. I ran across an article about it some weeks ago that there was still some "dark" (ie: unused) fiber optic cabling out there and becoming a hot commodity. Its whats fueling alot of the expansions and upgrade capability since they can do so much more with it now then they did over two decades ago when your basic rotary phone was still using it.
Now that I think about it, it's been probably 15 years since I looked into it. Guess I should probably play a little catch up on its development and deployment.

Back in 1989 we built our cable plant FTTC 500homes passed one way 550Mhz system. That was what 19years ago.
In 1995 we went full two-way 750Mhz. That system is still running as is today with plans to reduce the homes passed using existing fibers and DWDM technology.
So in my eyes, cable was ahead of the game 20years ago and still can go another 20years without any major construction.

So is Charter where I live(San Luis Obispo, CA) Big deal. Fiber cable isn't the problem, neighborhood nodes is...
Amazing I can't access VOD sometimes...wonder why? |

What about cable systems built before 1989? lets say early 1970s. |
