these switches are designed to be connected to other switches.  This is basically core switch used to extend via fiber to other switches with GBIC's or other fiber converters like SFP's in them.  The only option you would have to connect it to a PC would be to purchase a fiber to ethernet converter liket this.

The Cisco 3508G-XL-EN is a core switch for connecting other switches together.  To use it properly, you put a GBIC cinnector in the slot (they slide straight in) and then connect the GBIC to a GBIX that is on another switch.  The other switch would probably have ethernet ports that standard cables (RJ45) that connect a computer NIC (Niet work Interface Card) to the switch port.
 
If you want to connect computers together, then you have the wrong switch.  The one you have is not designed for connecting your computer to.  It could be done, but you would need a special fiber NIC in your PC's and then connect the fiber to the GBIC's in your 3508G.  Expensive.  You can connect PC's and servers at Gigabit speed to a Gigabit switch (such as a Cisco SR2024 Switch) that uses Gigabit over copper (rather than fiber).
