I have a 3825 that i just got off the shelf(literally nobody wanted it) and want to make use of it. We currently have a co-location that is feeding us a fiber 100mb internet circuit. I am wondering if i can terminate that 100mb fiber to the e0 sfp port on the 3825. I know i can to a serial port but usually i've put devices that sit behind the router on ethernet ports and in front of the router on serial ports.

looks like it only supports the GigE SFPs, so maybe you need a fibre to copper convertor.
100 Mbps SFPs - only 7200 routers or above and various switches:

The good news is the 3825 is fast enough to keep a good fraction of
100 Mbps busy:

Can i get an expansion module that will support a 100Mb fiber connection. thanks
The interface card compatibility section on cisco.com says that

they support the NM-1FE-FX-V2 in the 3800 series. I doubt the earlier version (NM-1FE-FX) would work in the newer ISR routers, seeing as most of the other earlier versions of WAN and other LAN cards did not.
Cisco does have 100-Base-FX SFPs, but their compat matrix doesn't mention any routers, just switches.
