Reddit reviews 10GBase-SR SFP+ Transceiver, 10G 850nm MMF, up to 300 Meters, Compatible with Intel E10GSFPSR

More pics.

Some info: I used an old IBM server with an Intel Xeon Quad-core CPU @ 2.4GHz & 16GB of RAM. I think the specs may be overkill for what I'm doing, but it's what I had on hand.

I installed a dual port Converged Network Adapter into the computer and then two 850nm MultiMode Fiber transceivers. For those who are unfamiliar, the transceivers plug into the square holes on the Converged Network Adapter. (The square holes are called "SFP+ ports".)

I then connected one side to the the switch from my ISP and the other side to the fiber switch for my home LAN.

I'd be happy to answer any questions, but if you have time, take a look at this article I wrote about my setup. The article has a lot more pictures and a video.

Edit: Also, if there are any logs I can share, or benchmarks I can run, let me know. I'd be happy to do whatever with this thing if it could provide meaningful information to the community.

Edit2: fixed link for network adapter

On the off chance you're paying for more than 1 gigabit,
I found this page detailing what a 2 gigabit fiber install looks like from Comcast

They ran 2 regular multi-mode fibers (MMF, like in a datacenter), and he's using high-end Juniper and Ubiquity switches with 10GbE SFP+ ports.

(the SFP are the little rectangular ports, these https://www.amazon.com/gp/product/B00SWD0318/ )

This is all standard gear for pro-networking, but this is the first time I've heard of this for a residential install. So I guess I learned something.
That said, I would let the ISP handle the initial setup, and if its standard pro-gear, you can pick your choice.

So I have tried these https://www.amazon.com/gp/product/B016YK9CPI/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1

and these https://www.amazon.com/gp/product/B00SWD0318/ref=ppx_yo_dt_b_asin_title_o08_s00?ie=UTF8&psc=1

I have the same issue with both. It basically turns the port off on the NIC.

I have cisco 1gb sfp modules that work perfect.

I just dont understand why the modules i have tried fail.

I get my Intel SFPs for $20 from Amazon

one is fiber and one is ethernet.

x520-t2 is fiber and requires 10 Gigabit SFP+ modules such as https://www.amazon.com/10Gtek-Intel-E10GSFPSR-Transceiver-10GBASE-SR/dp/B00SWD0318/ref=pd_bxgy_147_2?_encoding=UTF8&pd_rd_i=B00SWD0318&pd_rd_r=639d6280-e69e-11e8-963e-55bdcc3215cb&pd_rd_w=Y0jvL&pd_rd_wg=4FnIy&pf_rd_i=desktop-dp-sims&pf_rd_m=ATVPDKIKX0DER&pf_rd_p=6725dbd6-9917-451d-beba-16af7874e407&pf_rd_r=S5K0T8PF2R2GGEJ2XWNV&pf_rd_s=desktop-dp-sims&pf_rd_t=40701&psc=1&refRID=S5K0T8PF2R2GGEJ2XWNV

The x540-T2 takes normal Cat5e/6/7 ethernet cabling.
