Fiber Optic vs Copper

pcnetworx1 writes "Recently companies, such as Verizon with their FIOS service, have begun to migrate from legacy copper to fiber optics. Corning (admittedly one of the largest fiber optic cable makers) is running an article which explains why it is actually cheaper to go for the fiber optics."

    It's not really that different. If somebody wants to wiretap your home's or business's Internet connection by climbing telephone poles or popping manhole covers, the fact that the connection is fiber just means they need to bring some splicing hardware instead of copper alligator clips, and have a co-conspirator / getaway-driver with you to explain why your fake phone company truck is working at Midnight ("because that way it won't interfere with our customer's business", which is true for real repair people as well as wiretappers.) It's a bit more of a skilled job, but it's not the easiest place to attack most businesses anyway. More typically, you're an insider, but if you're an outsider, you want to crack into the victim's firewall over the Internet, or email them trojan horses, or if you *must* do hardware, you want to get into their phone closet where they've got the yellow sticky with the router password. But it's probably an inside job.

  2. A new way to go online!? by TheZorch · · Score: 3, Interesting

    I will be thuroughly impressed if fiber can be brought from the pole into the home. A analog/digital converter would allow uses to keep using existing phones on an all fiber phone network, but a whole range of new products could be used for digital Internet access. DSL doesn't work via fiber optics, so an all fiber phone system could usher in a whole new type of Internet service via the telecoms and at speeds that exceed what DSL can offer right now. Regular modems would still work but much more efficiently than before since fiber isn't volunerable to EM interference like lightning from thunderstorms, high-tension powerlines, peak cellphone usage (yes this does effect copper landlines), raido signals (try going online via an unfiltered phone line if you live near an airport), and sun spots.

    Fiber lines are harder to illegal tap. There is a device that can connect to a standard copper pbone cable without piercing the outer insulation. By turning a set of dials you can listen in on all of the phone conversations going on through that cable. Such a device wouldn't work on a fiber line because it exploits certain laws governing electromagentism and how electricity travels through wires. In order to illegally tap a fiber line you'd have to cut it, that would disrupt service for a while, and its would instantly be noticable.

  3. Fiber to the home by Anonymous Coward · · Score: 4, Interesting
    I gotta say I work for a Telco that is now installing "Fiber to the Home" and it is great. The ease of use and setup is fantastic. We are just in the process of rolling out this service and provisioning an new customer is very easy and it is great to work with a device 40 miles away and have no lag, after doing the same kind of work with Cable Modems and Dialup over the years this has be the way to go.

    We support 802.11 wireless (it sucks, The technology isn't reliable and most people don't understand how to use it!), Cable modems, Dialup, fixed point wireless (this sucks worse, slow and almost unusable), and now "Fiber to the home" of all of them the fiber seems to be the best. We are even considering replacing some cable lines with fiber in existing builds where we have had problems with the cable or we have higher bandwidth demands.

    I know the cost is more but maintenance is much lower and that is what kills you in the long run, going out and splicing a rodent chew. Fiber just doesn't have the same problems.

    Just my opinion, but I use it now, in the real world and it isn't speculation at this point.

    10x more expensive ?? Why are they then using single mode fiber where multi mode would be enough (single mode is more expensive than multi mode) ?
    I do not really buy the 10x more expensive argument... glass (even flawless) is cheaper pr. kg than copper... and btw. you can multiplex a signal on a copper wire too...
    Where I live the most expensive part of laying anything in the ground is the digging.
    There is one factor that in fact makes fiber cheaper than copper: glass is corrosion-free and will last forever.
