I have a 3750 with 12 SFP ports doing routing at a remote property. I also have a backup T1 connection on a 2821 Router. I need to be able to connect the the gig ethernet RJ45 connection on my T1 Router to a port on my 3750 switch so I can do HSRP. I am trying to find a compatible SFP module to work. I couldn't find anything on Cisco's website. Does anyone have any suggestions?

I found these items on google but I want to ensure compatibility.
