What is difference betwteen a SFP / GBIC - mini GBIC WS-G5487?
I have no nothing about 1000 BASE-T,LX,LH,SX etc. & Cisco Compatable SFP/mini GBIC.
What do these terms stand for?
Can anyone give a brief summary about this?
The 1000 stands for a data transfer rate
of 1000 megabits per second.
Base gives you information about the media (wires of some sort)
'-T' tells you which of the several competing 1000Base implimentations
has been used. You need to research the details, though, as the '-T'
by itself has no meaning -it's just part of the name.

LX, LH, SX are terms used in fibre optic communications and designate
the frequency & signalling standard to be used over the fibre line.
SX is commonly used within one building between closely adjacent
buildings; the 'S' hints at "short distance". There is a specific
frequency of light that is used for SX, & it expects a type of
fibre known as "multimode" -- which is a type of fibre that can
carry several signals simultaneously but tends to disperse
the signals relatively quickly.
LX uses a different frequency, and is more suitable for longer
distances. The 'L' can be read as a hint for "long distance". LX
