Solved Fiber Optic to Switch to Firewall:

December 8, 2014 at 11:29:48
Specs: Server 2008, 4gig
Forgive me if I may not be explaining this correctly...

My current enterprise setup is a T1 uplink to router/firewall and then uplink from router/firewall to switch. My company will be moving soon and at the new building the IP will be running a fiber optic from the demarc location. This completely changes my setup and I need some major clarity on this. 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? I hope this makes sense and all help appreciated.

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.

I would suggest its better to install a fiber wan interface in the router to handle the fiber connection. Been my experience converters are just another point of failure.
