Hello everyone,
I am one of the fortunate ones in our building who will be getting the Business 2G fiber installed.
I have my own internal firewall/router that serves the office.
I tried asking one of the installers about the ONT, but he wasn't able to provide details. I would like to be able to set the ONT into Bridged mode for both fiber lines. Will this be possible or would I be able to provide my own ONT functionality in my own router.

Could anyone provide guidance. I prefer to be prepared prior to the install happening.

Thanks

p.s.
Wanted to thank the crew that came out for a walkthrough at the Union St. building in San Francisco.

For residential fiber, Sonic uses ONTs from Adtran, like their 621X or 401/411. You might look at the datasheets and whatever info you can scrounge up about these and other Adtran ONTs.

What is the "business 2G fiber"?
Is 1 Gbps too little and they are bonding two fiber links?

Is the ONT accepting the two fibers and exposing a single connection where to connect your router to or do you use a router with two wan ports so it's not 2 Gbps but 2x 1 Gbps (so you cannot transfer at 2 Gbps but you can have two connections using 1 Gbps each)

In Oakland, I believe I remember sonic started to install 10 Gbps. The Adtrans box is ONT and router in a single box and i think it does not offer bridge mode yet.

From the Sonic Knowledge Base: "The iPhotonix 7251G is an ONT that Sonic utilizes for Small Business Fiber customers. It has the ability to provide two separate Fiber networks, both of which are dedicated 1,000Mbp/s lines. These networks are completely independent of each other and can not be aggregated."

This device is only an ONT. It has four Ethernet outlets, to which you presumably attach router(s) and whatever.

Thanks for the replies.
Eventually I came across the ONT and the explanation. The only thing is that the darn thing is not Rack friendly.

Once the install gets done I'll post an update.
