@Riley_S thanks. I already have fiber service with AT&T and the one person I talked to at AT&T seemed to not have clue of what I was asking. Thanks tho. 

  @x00 already looked into this with AT&T.  Because they no longer use external ONT's, and because of how their backend is set up, there isn't any way at present to use SFP+ with AT&T's fiber service. 
 

You have to use their gateway, which has the ONT built-in, in pass through mode with your router (all vendors).  
 

PS, it's the same with most other ISP's that provide internet access via fiber in the US. 

  @Richardj186 thanks. I figured this was the outcome honestly. I'm not a fan of using isp provided hardware and if you have att then you probably know how bad the WiFi is on those units. I was hoping this may solve the issue of too many devices all in one place but seems like no matter what I get I'll have to run the modem in pass through and have an additional device. Thanks for letting me know. Def helps me in deciding how much to spend as well....

  @x00 with the latest 4.27.7 firmware the WiFi has markedly improved. Not as good as using my own router. 
 

Currently I'm using the Archer GE800, TP-Link's gaming router. I don't know what your budget is, but it's $599, with frequent sales on Amazon and Best Buy websites. Very powerful, great signal all over, and almost non-existent lag when gaming AND watching a 4k movie at the same time; incredible pulling that off.

This is entirely incorrect with respect to att. Options exist to bypass their equipment entirely by using a third party onu/ont sfp module plugged directly into a switch or sfp port in a nic or firewall. These options have now been available for at least 2 years.

One has to first determine what specific fiber implementation is installed.

For gpon, att uses two different options, one with a 1310 nm wave length, other with 1550nm (alt optics). If you have the latter, you are sol.

With 1310nm there are several options that work.  Most popular one being the odi dfp-34x-2c2 (or 2c3). The first requires a SC UPC to SC APC adapter, the 2c3 accepts the att fib connector directly. Both are available on amz/ebay/aliexpress. To actually make it work, a number of parameters are configured in the sfp. There's also 4 or 5 that are copied from the existing bgw.  Effectively the sfp mimics the bgw320 from att's perspective, without all the limitations and headaches the bgw brings. In addition, some areas enforce 802.1x from the OLT, so you'll need to acquire the eap certs from your bgw box.

If you're on a xgspon connection (1270), the recommended sfp is the azores was-110. Similar process to copy over settings, and no eapol enforcement. It's a pricier module at 150-200 USD and should be plugged into a 10g sfp+ port.

  @das1996 how do you identify what fiber implementation you have?
