      Fiber will allow even higher speeds in the future, and it's less likely to be damaged by water than copper. If you can get it installed for free you should do it, later it might cost extra.

        FRICK FIBER

          Up until late last year, the only internet provider in my town charged $100 per month for 70mb/s down, 3mb/s up. This was the most expensive plan they offered. Literally everything else was worse.

          Fiber comes in, and I can get 2 Gigs up and down for the exact same price, and free installation so long as I put my home on the drop list.

    Kinda. GPON splits bandwith between multiple users. We do 1:8 splitting so 8 modems get 2.5Gbit/s. Some ISPs do up to 1:64 splitting.
    And the cable connecting the distribution station also only has 10Gbit/s in our installations. But even in places where more than 200 homes are connected, we don't really see those 10Gbit fully utilized at any time. Most people barely use their internet most of the time.

      Depends how oversubscribed it is.
      Docsis doesn't slow down by definition it's not in the spec that it must slow down it's just how statistical multiplexing works on shared links.

      Many of the same concepts apply from DOCSIS to PON because they are both the same physical medium and use point to point tunneling the only difference being that data a PON transceiver sends upstream is never received by any other receiver because of how the splitting works. This is different to DOCSIS since all data is received by all nodes up and downstream.

      Like this anon said, oversubscribing the OLT switches is common as well, most ISP's don't run 100Gb links to their access shelves even if at load the traffic would far exceed what is commonly used (10-40Gb links). It's not worth it to an ISP to buy that sort of transport from a different service provider since most ISP's don't actually own all their own cables they buy it from someone else and if they do own their own cables it's not really worth it to them to buy the high speed optics and router line cards with the licenses.

        Probably many. They offer the same speed with coaxial so why switch?

          If most people switch and a few don't, the ISP will turn off the old equipment at some point and then you won't have anything at all.

          From a buyer point of view it doesn't really matter, I was just explaining why a connection across either cable or fiber might slow down, and in both cases it's the same reasons.
          -statistical multiplexing on shared medium
          -oversubscription of link to core service provider network

          you can buy whatever you want

        Most optical equipment is GUI, that's how most telecomm stuff has been for quite a while. IP Routers have almost always been CLI terminals. You would think it would be the other way around but not so.

        Almost every ROADM or transponder shelf I have seen starts you off with the GUI first.

    In theory yes (assuming PON rather than point-to-point), but in practice it's more future proof.
    e.g. if GPON starts proving insufficient for a given PON, it can be upgraded to xgpon/xgspon/whatever just by installing new equipment at each end- no need to lay more fibre.

    >Is fiber plagued with slowing down with more people using it, as coaxial is?
    Yes and no
    Yes insofar as fiber doesn't have unlimited speed
    No in that the limit is multiple orders of magnitude higer and creeping up over time

    but the biggest issue of copper was never so much max bandwidth, and more how quickly signal degrades (hence why ADSL speed depended entirely on your distance to the ISP aggregation point)
    fiber is also less (not "non") susceptible to this; we need repeaters, but rarely enough that at "human" scales (say, a city), fiber works more or less as if it was perfectly stable
    (comparatively to copper anyway)

    point is that fiber is a fundamentally great material to build upon, with very little drawbacks, hence why everyone adopted it

    Well not as bad the jitter is less as well as latency but if the relay in the neighborhood is overloaded it will slow down but not as bad as copper since the junction on the pole is shared with your neighbors as it makes it's way to the relay.

        I have something like 50/10 or thereabouts. There's billboards up in my town about how fiber is supposedly coming soon but I don't so much want it to be faster as I want it to be cheaper, and I'd wager good money they won't do that, they'll pitch fiber as an expensive premium option

          i gave up getting anything cheaper. im paying $140 before tax for 1gbps + unlimited data addon. $50 alone of that $140 is for unlimited data. but being in a household of 5, 3 being under 18, data is burned through like candy to a fat kid in a candy store

            yeah I live alone and don't stream so I rarely manage to burn through more than 100GB or so. But even the slow option is fricking $70. That's AT&T, there's a cable company too which offers something faster for... the same price. Also when I had them it would drop out several times a week, sometimes for hours. I got sick of b***hing at their support and getting them to send techs out who ran though the same checklist and never fixed it, I'd rather have "slow, but it works". But more than that I'd rather have it for thirty bucks, I have no inclination to spend $140 for fiber.

            Well, unless they give me a proper dynamic IP and reconnecting gets me a new one. My IP is allegedly dynamic but it hasn't changed in two years, so I can't shitpost too hard. but I've never talked to an ISP salesman who knows what an IP address is.

            that's one thing that annoys me because my ip is semi static. it will only change if i unplug the modem for a full 24 hours. if not, im stuck with it until the next modem reset or 24 hour power off. and modem reset only happens if i buy a new modem or my isp issues a new firmware update for it.

            doing a lot better than most then. i would love to pay $140 for 2gbps with no caps vs my current $140 total for 1gbps + the no data cap addon. don't mean to come off a boomer but i really miss how cheap stuff was a decade ago. back in 2008 when my wife and i got our first house we would pay $150 for internet (no caps), phone, and tv. amazing how worse things got in such a short amount of time.

            for a full decade. I was so happy when not one, but 2 fiber providers decided to expand into my town.

            Cox is the other provider, and they DO have a data cap (1.25 TB) and overages. So the choice was easy for me.

        GPON is kinda shared but it's mostly not something that's possible unless they put too many users on 1 OLT which if I had to guess is downright nonexistant.
        >as coaxial is?
        Your ISP is cheaping out, using shitty modems without enough channels.
        24x8 EuroDOCSIS 3.0 here. 600/60 or it just doesn't work at all. 1000/100 possible, but that's pushing 3.0 to the limit.

          There are places that run hundreds of customers on a single GPON OLT.

            Oh I do. My biggest issue with DOCSIS is that the ISP removed bridge mode in the firmware of every HGW. No amount of chocolates, cookies and cocoa powder they send me will make this acceptable. But my other option is to drill a hole to get a rusty ADSL line. Getting fiber in the building is quite the fricking process, despite it being in every damn street.
            >in smaller more corrupt countries.
            ... Like Serbia? No such GPON issues here but everything behind it is subject to morons, one time the exit link broke for a while and only SBB users could access anything outside the country. All LTE and DSL users affected too.
            >There are places that run hundreds of customers on a single GPON OLT.
            I mean, if it can connect that many surely it can handle it?

            Sure, but when you're splitting 2.4/1.2gbps between ~100-200+ customers, you're gonna get the same bandwidth sharing issues congested DOCSIS networks deal with.

    i have cable, 1gbps, runny off coaxial. never seen slow downs. household of 5, all streaming, Internet stuff, and games. though i am forcing everyone one else to wifi 2.4ghz to limit them to a max of 200mbps lol. i keep wifi 6ghz band to myself for my lappy along with direct Ethernet to my desktop. that could be why lol.
    but my cable provider stopped finer rollout about 3 years ago now. initially they were converting neighborhoods to fiber, for free. but stopped after they had some "breakthrough" that allowed for speeds 2gbps and higher on coax.
