Priscilla,
As far as I understand, all Ethernet media adhear to the 52 bit-time rule.
Full-duplex
media has the loopback and collision detection disabled, but it still has
exactly the same
mechanism as half duplex ethernet.
However the particular statement is true for Multi-mode Fiber (MMF) where
half-duplex distance limit is 412m and the full-duplex limit is 2km.
