I currently have some fiber that runs between two buildings. The distance has to be less than 1000 feet, Honestly Im not sure why they ran fiber instead of just cat 5e. A guess would be around 700 feet. I have two cables that run into 3com switches . The connections are labeled:
100 BASE-FX
100Mbps FD FC

The fiber goes into a leviton cable thing and then comes out into 3com switches at both ends. This is 62.5 micron fiber.

I have a few 3com 4228 switches that have GBIC inputs. If I get GBIC inputs that support fiber will the existing fiber be able to connect at Gigabit speeds?

Will this fiber even support gigabit connections?

Any help is greatly appreciated.
