Currently we are using 62.5u fiber between the core switch and the uplinks from our access switches.
If we change from 62.5 to 50 do we have to replace the GBICs and 1000base SX SPFs? I realize I'll need new patch cables but not sure on the fiber transceivers.
Reason I'm asking is we've tasked our wire installation contractor to rum more fiber strands between two bldgs., and he is suggesting that we go with the 50u size.
you can use existing gbic for the new fiber.
