where can I get router / cable modem with fiber?I wonder how they use fiber optic for the Internet? Because I dont see any company selling a cable modem or router that has fiber optic port. I Know they do sell fiber optic switches. |

Well there is no modem (I dont think) its just direct network.. just using gigabit card and switches. |

Re: where can I get router / cable modem with fibeThe high-dollar stuff converts the data signal/wavelength to Ethernet on the outside wall of your house to copper ethernet for your house. Others just use a "media converter" as the endpoints of an otherwise common [large] office LAN in your neighborhood. The cable companies do use something called an optical modem...not useful for anyone else though. |

Re: where can I get router / cable modem with fiber?Fiber optic networks provide a HUGE amount of capacity, and just because you don't have a fiber optic cable connected directly to your computer, doesn't mean there isn't one after the first few hops. Fiber optic cables are expensive (high quality Alcatel cables are somewhere around $0.95 per meter) and if a cable company brought it to everyone's home, then the cost would be massive. Not to mention the multiplexers that convert the signal from digital to RF are extremely expensive. The more wavelengths a multiplexer can handle, the faster the data flow is. Take an OC-192 for example, they have a capcity of 10 Gigabits per second, which is roughly around 1192.1 megabytes per second. These allow higher speeds from your cable company and telco.
Fiber is a great discovery that is going to allow many of us to experience speeds unthought of.. |

u guys dont understand, there is currently no cable modem or router support fiber optic, so even if I get a gigabit switches with fiber optic ports and fiber optic, they would be useless because the no cable modem or router support fiber optic right now. The signal has to be fiber optic right from the cable modem to have the performance that we want with fiber optic. I hope I made my point right. |

Get a core router and you'll see that it has fiber support. |
|
|
what's a core router? and what company sell it???? is it for desktop or home user? |

You have to make sure your ISP supports the router. Also take a look at the spec sheet for the core router and make sure the router setup, laser diode & photodiodes pickup the wavelenghts that your ISP uses. If I were you I would use whatever hardware your ISP provides and and use a regular router (since the last few feet to your PC will be CAT5 "Ethernet" cable. |

I dont understand what you guys talking about. What Im asking is is there a router with fiber optic port so I can hook up my fiber optic cables (wire) to it. If there's no router with fiber port, then there's no point in buying fiber optic cable wires or switches , no performance gain. |

I thought that fiber optic was a fine strand of glass. That is what my fiber to the home is. That a gateway converter takes a laser light in,converts light to electrical,and sends the last few feet of signal,electrical, through cat 5/6 cable(copper) to a router then cat 5/6 (copper) cable to all computer desks.. |

Re: where can I get router / cable modem with fibePlastic Optical Fiber (POF) is pretty lame -- with a very short reach. But there is probably a converter for it (re: » www.ctsystem.com ) |

It has some advantages. It's not meant for longhaul. » www.agc.co.jp/lucina/eng ··· eng.html |

A 16 port fiber switch |

Virtually all router switch companies have optical port options (even if only one main upload port). The cost for that option far exceeds the cost for a simple cheap media converter. Does that explain our ignoring that option? As I recall, the cheapest 24 port optical [L2] switch I could find was about $180/port. A simple unmanaged optical converter can be had for as little as $75. I really wanted the simple elegance of an all optical network -- but not for that kind of price difference. |

He wants a router, not a simple switch. |

Re: where can I get router / cable modem with fiber?Plenty of routers and switches have fibre optic ports... You need to help us help you, though.
Do you want 100BaseFX? 1000BaseFX? Sonet (OC3-12-48)?
Fibre is just the media, not the technology.
Cisco/Bay/Nortel/Juniper/DLink all make routers and switches with some type of fibre connection....
For instance, I just installed a Cisco 12410 core router at work last week - with about 10 fibre ports, running at either GIG-E for local connections, or 10G (POS) for backbone... And if that doesn't mean anything to you, then you probably don't need a fibre switch at home...
YMMV - Heath |

Come on, that's the catalog price. Usually you don't buy only one. The system has been deployed in my area, and I don't think they didn't get a substantial discount. And it is a EPON ONU. |

Actually for the passive routing and single strand WDM -- the cost could be understood. That is it's not really just a straight-out media converter. PON switching logic is rather involved. WDM adds a bit more as well. Still, maybe $200 would be more like-it. |

That's exactly what it is. |

Re: where can I get router / cable modem with fiber?why u guys get the converter for? ther's no performance gain if the source doesn't have fiber port (the source is the cable modem), for example Let say you have a regular cable modem, and after that you have a converter which converts to fiber, how can you get the performance of fiber? i dont see how it work out, can somone explain? |

Re: where can I get router / cable modem with fibeIt wasn't clear what you meant -- and nobody would usually think of such a scenario. I mean you wouldn't hold a wine glass under your water-faucet and expect Merlot now would you? Then who would expect fiber to enhance a slow copper based connection? (you might run fiber from a T-3 45mbs connection)
However -- you could use fiber from a cable or DSL modem and still get the distance advantage of fiber. Copper UTP is only good for 100 meters. Fiber media converters are good for 20 thousand meters (20km) -- or more if you like -- to 40-60km .
Why you'd need to do that is about as strange as hooking fiber up to a DSL/cable network to begin with. But, thats the only benefit I can see for the effort. [text was edited by author 2003-10-26 11:59:15] |

Re: where can I get router / cable modem with fiber?There is no modem to connect to a fiberoptic line. Fiber is terminated at a box outside or inside your house. From there, you use category 5e ethernet cable to take advantage of the 10 or 100 mbit speeds. There is no cable modem. You hook directly into the terminal box or use a router in the terminal box lan port. Does that help? |

heh I thought he wanted a router w/ fibre input for ffth ISP.. now that I read the topic title again it seems to make no sense if he wants a cable modem (which uses copper coax) that uses FO cable... |
