This article details some standard or advanced knowledge. The official support may not cover the knowledge detailed here. As usual, (the lawyers would argue that) you are responsible for all the changes made on your equipment. This article does not provide warranties of any kind. By following the knowledge detailed in the article, you agree to hold both the article authors and Verizon harmless.
To get a working Internet connection that supports multiple devices, you need a router that does Port Address Translation (PAT). Typically, all consumer routers, including Fios and Verizon routers, have this function enabled by default, and no way to disable it either (well, this is not true in Fios/Verizon routers, but I digress).
You need to make an Ethernet connection between the ONT and the Router. I tried to generalize for all popular PON deployments. For those with available speeds up to 1 Gbps, you have the GPON ONT, which is typically the Nokia I-211M-K/L. For those with available speeds up to 2Gbps, you have the NG-PON2 ONT, which is typically the Nokia TW-210X-A, or the Calix 812NG-V, which is paired with the E9-2 platform OLTs.
ONTs may or may not have a fiber attached. Do NOT stare into the ends of a fiber, or the transceiver on the ONT! This is a Class 1 Laser device, but the wavelength is in the infrared (IR) range which one cannot see, so please be careful.
F-type Coaxial Connector
The Coax on the GPON ONT is usually not used for delivering the Internet, unless you have a speed tier lower than 100Mbps, which is rare. The Coax on the ONT may still deliver analog video for Fios TV services, if your area is still not upgraded to IPTV.
The Coax on the CR1000A/B cannot be used for a WAN connection. CR1000A/B, unlike the G3100/G1100, only has one MoCA chip tuned to the D band for MoCA LAN. The Coax can still be used for MoCA LAN, which can connect the DVR, Fios Stream TV MoCA Adapter, STBs, and other kinds of MoCA to Ethernet bridges.
Because Coaxial cables are shielded, according to NEC 800 chapters, one needs to ground the shielding. The GPON ONT has a grounding screw hole for this purpose. The Coax port is eliminated on NG-PON2 ONT for IPTV, so no more grounding requirements.
Plain Old Telephone (POT)
This is so plain, so nothing to talk about. It connects analog telephones, but voice is carried on SIP and VoIP past the ONT.
