kudos:1 | Re: actually Time Warner is partially correct 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. | |

Remember when you had to call in by phone to get PPV? 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. | |

kudos:1 | Re: actually Time Warner is partially correct So your saying that all cable TV systems were fiber from day 1, even though they were 1 way systems? | |

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. | |

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.

kudos:1 | Re: actually Time Warner is partially correct What about cable systems built before 1989? lets say early 1970s. | |
|
| | | 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. | |

3 edits | 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. | |

| | | | Re: actually Time Warner is partially correct 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.
