Great module at a very affordable price. My journey started a little over a week ago. My UCG-Fiber kept getting assigned an address from 192.168.1.0/24 for a handful of minutes per day, completely cutting out the internet. Furthermore, AT&T will only delegate a small number of IPv6 subnets (one /67 by default, not the 16 /64s I am allocated) to a downstream router. I was fed up with AT&T’s BGW320-500.
I dug into the wiki and then the Discord and I came upon EXEN’s cooler and X-ONU-SFPP. Literally 15 minutes after I ordered, the device was already shipped. The unit is pre-flashed with the latest firmware, and worked great out of the box.
I spent less than 15 minutes from unboxing this unit until I was online. Now, it’s only been a little while, but my connection pings are already much more stable and I shaved off about 1ms from my latency. Just look at the screenshot — you can clearly tell how much more stable my latency is when I bypassed (just after the blank lines). I have a full /60 allocated to me and each of my VLANs has its own /64 delegated to it.
If you’re wondering whether you should bypass your AT&T gateway, just do it!
As a new AT&T fiber customer, I loved everything about my new fiber service aside from the big clunky BGW320 I apparently had to use even though I was using my own 10Gb UCG-Fiber router and WiFi access points.
While researching my options, I found the most fantastic 8311 community which had custom firmware I could load onto a specialized SFP+ module to act as the BGW320 allowing me to bypass and remove it entirely, I just needed to purchase a module.
Unfortunately, WAS-110 modules were mighty expensive and many vendors were affected by additional tariffs, possibly costing over $200 by the time it was in my hands. Some still needed to be flashed and others from foreign vendors, I couldn't exactly trust the flashed firmware wasn't modified in some way.
Then I discovered EXEN's X-ONU-SFPP offering, a WAS-110 alternative that arguably the same if not better, much cheaper, re-flashed with the official 8311 firmware and since he's importing them, there's no surprise tariffs! Exactly what I wanted!
I purchased this directly from EXEN along with his custom UCG-Fiber cooler which netted me an additional discount plus they shipped together.
They arrived in a timely manner, perfectly packed and protected.
The bypass for XGS-PON was made dead simple thanks to EXEN's preflashing and worked on my first try. I cannot recommend enough going this route for simplicity above all else. The UCG-Fiber cooler was also very well made, fits the dimension of my router perfectly and I'm confident it will last a long time.
Thanks again EXEN!
