|I presume I will need to configure a port on my switch that sends an uplink to my router which now will only be used as a firewall and then run another uplink from my firewall to my switch?|
You should already have a port on the switch configured as an uplink to the router if they're connected at present. You should not need to change anything between these two devices. The only thing that may need changing is where your external provider connects to your router.
The only difference between your existing setup to the new is the media involved in your external connection. A T1 is copper and fiber is fiber.
For A fiber optic connection you have two choices, you can go through a media converter to change the fiber to copper. The second choice is, if the device you're connecting the fiber optic to has a GBIC (fiber) connector, you could go directly into that with the fiber.
So to sum up:
Device without GBIC:
Fiber >> Media Converter >> Copper (network, patch cable) >> Router
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
