Do I need to get a modem for fiber optic?

Verizon will terminate your fiber to an ONT... this ONT will have Ethernet ports and most likely POT's as well as Coax to for cable tv. The below picture is an example. In many cases this ONT will act like a bridge, but it is feasible that it will act like a router. We utilize both types in our network.

Okay, so once again, the internet has confused me.

 

I have Verizon coming in a week to setup fiber optic in my new building and I told them I want to get my own equipment. I am planning to get a $300 802.11ac router but I cannot find any "fiber modems". I can find DSL and cable modems. My understanding was that fiber optic was an entirely different type of cable and therefore cannot connect to a cable modem.

 

Any ideas of what equipment I should get? Any advice on which router, haven't decide yet? I want to be able to add repeaters as well, not extenders though.

Do you have fiber to the premises or fiber to the cabinet? It makes a difference, if you have FTTP you need equipment to change from the fiber cable into something a router can understand, if it's fiber to the cabinet then the section between the cabinet and your building is copper which would be different again.

Damn, I am not actually sure. What would the difference be, if its fiber to the premises, and cable to the cabinet, I would get a cable modem, and if its fiber to the cabinet then...?

A quick google seems to suggest Verizon (which would have indicated you were in the US had I read that!) use FTTP.

 

So what does that mean exactly, I will need a modem?

You will need a modem specific to FTTP, most likely one that will accept the fibre connection. I can't seem to find any modems that have a fibre connection, however, so you micht have to contact Verizon and see what connection the modem needs to have.

As far as I know, your ISP should provide a suitable modem. You can still use a router behind it to do the actual network management. That would be the easiest way.

 

EDIT: At least that's how my ISP works- they have a separate modem model for FTTP and ADSL lines.

What do you mean with a router "behind", just making sure I understand :)

Plug the modem into your main fiber connection, and then plug your router into the modem. Hook up your PCs / WiFi onto the router.

Oh okay, nvmind :) I knew that. Still don't know if I need something called a "fiber modem" or if i can just get a cable modem?

That depends if the fiber cable will come all the way to your house.

From what I heard, Verzion installs their own cable modem/router which gets internet via COAX. The Ethernet on the ONT device that @schizznick showed is locked by Verzion. However, you can ask the Verzion tech guy to unlock it for you when he installs the box.

 

Maybe this has changed, but I know that's how they did it before.

If you get FIOS TV then by default they will use the coax from the ONT for both your TV settop boxes and for your internet, using MoCA. The router would need to support MoCA for WAN in this case (the one they will rent you that they call their Gateway does). When the installer comes you can ask him to enable the ethernet port on the ONT as well. If you don't have FIOS TV service then they default to ethernet. So said my FIOS installer about two months ago.

Note: A normal cable modem uses DOCSIS, and is not compatible with MoCA.
