AT&T Fiber Installation Process

Before converting to fiber, I want to know step by step what the technician has to do to complete a fiber installation at my house. What's involved?

Normally the installer will ask where you want the Gateway to be located, and look at options where the fiber will enter the home and discuss this with you.

The current standard model for AT&T is to bring drop fiber from the tap to the point where it will enter the home; they may terminate the drop at the external wall, or they may pass the drop fiber through the exterior wall to where it will terminate inside.  Either way, they will likely need to drill a hole through the exterior wall for the fiber to pass through.  The fiber that comes inside will be terminated at a wall plate.  The location of that wall plate may be determined by the AT&T Gateway you get.

It matters a little what equipment the installer has and what service you've ordered.  If you ordered 5 or 2 Gbps Internet, then you'll need a BGW320 Gateway and you will not get an ONT.  If you ordered 300, 500, or 1000 Mbps Internet, then you might get a BGW320 or you might get a BGW210 and a separate ONT (depending on whether XGS-PON is available in your neighborhood and whether the tech has a BGW320 he can use for your install).  

The BGW320 will be connected directly to the fiber wall plate by a fiber cord (normally a couple of meters long) through an SFP+.  With a BGW210, the fiber will be connected to an ONT (a separately powered box) and the ONT can be connected to the BGW210 via Ethernet; this allows you to have the fiber wall plate near an external wall in one part of the home and the Gateway in a more central location.

The AT&T Installer will normally not fish the fiber through walls.  He may pull the fiber through conduit (that is in-spec for fiber) if you have a pull string in it for him to use.

The Installer will normally check the light level where the fiber is terminating and then connect and register the ONT (either the separate or the one built-in to the BGW320) and make sure it connects properly and that the Gateway comes up and that you can get an Internet connection through it.  He may do a speed test with you.  He may help you connect one Ethernet connected device (given that he's not going to fish cables).
