Question : Fiber Backbone

Dear Experts

I have 4 cat5e backbones running from my server room to 4 different departments in the building. One of the backbones currently is doing on average 192,895,877.625 kilo bytes per day, at an average speed of 18,487.453 Kbits/second.
The switch in the server room is an HP ProCurve Switch 2824, which has 4 fiber ports and the other a normal unmanaged gigabit 24port switch.
Would it be advisable to convert the current cat5e backbone to a fiber link and would this increase the current speed of the data being transferred to and from the server room over the backbone ?

Answer : Fiber Backbone

Given that your switch is gigabit, if your copper wire is up to specs, and you connect to a gigabit interface at the server room, then simply upgrading from copper to fiber won't buy you anything. Gigabit on fiber is no faster or better than gigabit over copper. You get longer distances with fiber. You get electrical insulation with fiber. You just can't go any faster.
Now, if the copper cable is not 100% up to TIA/EIA standards, then you  might only get 100M out of the link and not the 1000mb that you should be getting. Then, yes, fiber to the gigabit ports will certainly increase capacity 10-fold.
