Plugging SFP transceiver from AT&T box directly into SG-2100
-
@keyser It's by default on 1G I think. But it's a OLT not a ONT so it's useless. I go for the FS.com module.
-
@gtaxl: I have a couple of pictures of the module now. There was no time to mess with plugging it into the SG-2100 directly.
Here are the pictures:
The unit is a Nokia XGS-PON I-temp 1270 TX. I am trying to find specs on it, but haven’t had much luck. One of Nokia’s white papers says that an XGS-PON is a “10-gigabit-capable symmetric passive optical network.”
So, is the AT&T fiber coming in pulsing at 10 Gbit/s, but throughput is throttled at the CO or somewhere else, or is that module compatible with multiples speeds.
-
@dominikhoffmann yeah that's 10Gbps, won't work with the SG-2100. Cool to know what module it is though.
-
@gtaxl: What’s your explanation for why it won’t? Is it that the electronic interface’s timing specs don’t match?
Could I use a different, compatible SFP transceiver, instead, and make it work with AT&T’s 10 Gbit/s fiber? My guess is that, if so, I would have problems getting the transceiver provisioned by AT&T.
-
@dominikhoffmann You'll need an SFP+ port to use that. The 2100 is a 1G SFP only.
-
@dominikhoffmann My understanding is if you have an older ONT then it is 1Gb on the fiber, if you have the newer service that can go above 1Gb then it is 10Gb throttled at the CO.
-
@andyrh If you have an XGS-PON it's 10G.
XG = roman numeral 10Gig
S=Symetrical
PON = Passive Optical Network -
@jarhead Mine is a 6 or 7 year old ONT screwed to the wall. I am certain it is 1Gb. My area was one of the first to get fiber in the city, and I was quick to sign up.
-
@andyrh I'm not doubting that. Just telling you the nomenclature.
You probably have a GPON. -
I haven't read through all of the replies, but you cannot eliminate the AT&T gateway. First off, the newer models like the one shown have the ONT built-in. Secondly, the fiber service requires certificate-based authentication, so even if you clone the AT&T gateway's MAC address on your pfSense it will not work.
The previous workarounds also do not work like they did with previous AT&T gateways and separate ONT module. If you want any fiber plan over 1 gig, then you will be issued the same gateway as in the original post. Also note the LAN ports are all 1 gig with the exception of first port which is blue and will support 5 gig, 2.5 gig, or 1 gig.
