    fiber optics in networking

    by thetechman2014 ·


    When is fiber optic cable used. I’ll be honest I probably have a tough time even recognizing it when I see it. I believe I’ve only seeing the cat cable stuff. I don’t see it being used to connect to the computers they usually have ethernet ports that connect to the wall jacks. The switches I’ve seen seem to have cat cables that connect to the patch panel which seems to have cat cables punched down. I haven’t had a chance to look closely at the commercial routers to see what cables run to them. I hear a lot of talk about fiber. Where does this come into place is there something inside the comm room that has this fiber connection, but I don’t know what I’m looking at? Maybe something outside the building buried under the ground?

      You can have a fiber connection to your ISP. Then you need a modem with a fiber connection. That’s quite common, even for home use. Where I live, they are connecting every house this year, totally free. You pay for it when you use it (it’s 1000 Mbps), but the infrastructure is present everywhere, like it is for POTS (plain old telephone) and (coax-)cable.

      Inside data centers glass fiber can be used inside a network also, All you need is the right interface on both sides. And a fiber cable between them, of course. It’s faster than Ethernet. For your home LAN, Ethernet and WiFi generally are fast enough.

      Fiber optic cables are the highways of the internet! They use light pulses instead of electricity to transmit data, which allows for super-fast speeds and longer distances compared to the regular cat cables you’re used to seeing.

      You’re right, most individual computers still connect with ethernet cables. But fiber optics come into play behind the scenes, connecting things like switches and routers within the communication room, or even running long distances underground between buildings. So next time you’re in the comm room, look for thicker cables (compared to cat5/6) – those could be the fiber optic ones!
