ahh...yes when I got Verizon FIOS they ran the fiber to a box on the side of the house.
I helped when it was installed but have never DIY'd installed a fiber connection to my home.
I just didn't want willy nilly drilling in the side of the house cuz it was new such that I managed and watched the installation.
In the box you could run coax or ethernet cable to the router. The telephone dmark was plugged in to this box separately a few feet away. Telephone/fiber box power / backup was connected inside of the house close to the telephone dmark.
During construction I ran coax and ethernet cable from this side of the house to a central closet area in the middle of the house. I did the same on the other side of the house for a satellite dish.
If your modem is using two wires in an RJ-11 cable then it is not ethernet coming from the pole.
In the United States, ADSL is popularly known simply as “DSL,” which is a misnomer, since VDSL is also a type of DSL connection. Differently from ADSL, VDSL also allows the transmission of TV signals, so to the end user, VDSL is more similar to (and competes with) the cable TV system. Another characteristic that puts this system closer to the cable TV system is the use of fiber optics outside the service provider’s building, as we will see. In the U.S., popular VDSL networks include AT&T’s “U-verse.”
On DSL technologies, the limiting factor for speed is the length and quality of the cables used by the phone company, since it uses regular phone cables (twisted copper pair). VDSL solves this problem by reducing the length of the standard cable by installing an optical node closer to the user’s home, and the connection between this optical node and the service provider is done through fiber optics, while the connection between the node and the user’s home is done using standard telephone wires. This is exactly the same idea used by the cable TV, except that cable TV uses coaxial cables instead of telephone wires.
VDSL goes a step further, and allows the optical node to be installed closer to the user’s point of installation, shortening the regular telephone wires even more, which allows higher speed rates. VDSL even allows fiber optics to be delivered directly to the user’s home.
