Perfect for AT&T BGW320-500 Bypass!
I used this iszo SFP Stick ONU to finally eliminate the AT&T BGW320-500 gateway from my setup. It was relatively easy to modify the MAC, SN, and LOID to match my original equipment. Once configured, I plugged it directly into my UniFi UCG-Fiber, and it was recognized immediately. My connection is stable, and I’m seeing full speeds without the overhead of the ISP’s gateway. If you want a cleaner rack and better control over your routing, this is the way to go. It runs a bit warm, as most SFP ONUs do, but the performance is rock solid. Also got rid of the clunky "IP passthrough" of the BWG-320 that didn't work most of the time.

Supplier is very helpful
Works with verizon network and mikrotik Rb5011 router. I dont think it even needs changing of serial or anything. Supplier is very helpful and quick. I deleted my MAC and they were so quick to provide me with new one.

Missing accessories.
Does not come with media converter or fiber adapter as shown in the description. Will report back with functionality/compatibility if I can get it to work without. Update: Does not appear to be compatible with UDM-P. Though I could log in and update the config on my switch, when it is placed in the UDM-P, I get constant disconnects on the SFP port. Will BRIEFLY initialize, but almost immediately disconnects. Unfortunate, but I won't be able to get it to work without the media converter.

Works great with ATT Fiber!
Super easy to setup with ATT Fiber on their GPON network. Was able to disconnect the ATT gateway and just plug this straight into my firewall.

Didn’t work.
Didn’t work. I was hoping that it would be able to spoof my existing modem. No luck.

rebranded DFP-34X-2C2
Came with APC connector, which is nice, so we don't need the APC/UPC converter. Someone stated in the reviews before that it doesn't work with UDM Pro; well, it does work for me.

Works well
I use this product to replace the ONU from my ISP, which can gain quite will performance from it. It also free some space from my rack after remove big ONU box. It required some technique to setup and adjust, If you dont know what is this, this product is not for you.
