Excuse my ignorance here. I have tried googling this 100 ways and can't seem to find the correct wording to get the result I am looking for.

We have some fiber cabling that shows a MFG Date of 02-Mar-00. We are thinking about upgrading our LAN from 10/100 to xGB. Want to know whether we need to replace fiber cabling as well? So, my question is, how do you determine max speed of cable? 

Below is the wording printed on the cable

DX12-065D-W Series
62.5/125UM
Ultra-Fox Riser
Type OFNR (UL)
Indoor/Outdoor
02-MAR-00
