XG7100 Confirmation if you can plug in an SFP / SFP+ to RJ45 Adapter

@stephenw10 Thanks...
1Gbe is all that I'll require for now.
It'll be interesting to see the results of tman trials!
I'll order the Startech products and report back...

Using a 1G RJ45 module I'm not able to get a link in the 7100 SFP ports. The actual link is established but the module doesn't pass that to the port so the 7100 always sees it as down. That's using a 10G-tek 1G module:

That is the issue you may hit using an RJ-45 module.

@tman222
Very nice - is any of your equipment able to show the actual port power draw?

️

I'm afraid not, and unfortunately I can't see the temperature either. However, I've been using this transceiver / adapter for a few days now with zero issues. Great performance and no signs of any instability.

@ASGR71 Confirmed.
The above Startech products do work with an XG7100 for 1Gbe.

Set the interface up from tty and restarted the system and then
specifically select the speed from Interface->WAN->Speed Duplex->1000baseSX

Did have a activate/deactive issue but I think it was realted to
the LFP switch on the converter. Set it to off and all works well!

Thanks for all your help guys.

SFP1000SXST

That module? So that's a 1GbE Fiber module?

ASGR71

@stephenw10 Hi Stephen,

Yeah, transceiver manufacturer part number SFP1000SXST.
Not got the system setup properly but WAN address coming through.
So assuming everything else will work.

@tman222 Just want to report back my findings, so far. I procured a "10GBase-T(80m)" the chipset can be different depending on the length supported and, indeed, the 80m does include the newer (more power efficient Broadcom BCM84891L PHY chipset). Figuring that out is a little difficult as you need to go to 10GTek's website but we did confirm you do need the 80m SFP+ to get this specific chipset.

And, so far, it's working wonderfully - this SFP+ module was immediately recognized by pfsense in our XG-7100's. It also instantly negotiated 10G w/ our Calix ONT. Additionally, under "Status | Interfaces" it shows helpful statistics like the current voltage & temperature. The module is cool to the touch (from the outside, at least) and we haven't seen any issues thus far. One thing we noticed is that we aren't exceeding 1.7Gbps on 2Gbps service but I am relatively sure this a configuration issue w/ our ISP and not an issue w/ the SFP+ module or pfsense.

Hopefully, this helps other locate something that might work well for them, I spent a relatively significant amount of time trying to find a module that would work and luckily it panned out. In hopes of helping others I'll also share the amazon link I used for the module I purchased (10GBase-T(80m)): https://www.amazon.com/10Gtek-SFP-10G-T-S-Compatible-10GBase-T-Transceiver/dp/B094N9YKN9

Does it link at multiple speeds?

@stephenw10 next time I'm up there I can try and test connecting 1Gb RJ45 as a test. Our use-case is specific to connecting 10G RJ45 ONT's to our XG-7100's so I didn't test connecting anything lower than 10G. FWIW, the plan is to eventually go GPON/XPON on a stick but our ISP doesn't support that, yet, so we went with this setup for now.

seanmcne

@stephenw10 was able to test today - it only does 10Gb, I had it on auto select but it would only connect to other 10Gb interfaces (my 1Gb cable modem Ethernet wouldn’t successfully come up). In our case our two ONTs are 10Gb so luckily they work well for us.

stephenw10

Mmm, Ok probably can't see link rate to negotiate it. It might be possible to force it to 1G. Anyway good to know either way.
