- Diameter: 9 μm, 10 μm, 50 μm and 62.5 μm
- Wavelength: 850nm, 1300nm, 1310nm and 1550nm
- Number of wavelength: Multi-mode Fiber (MMF) OR Single-mode Fiber (SMF)
- supported distant range: in meters / kilometers
Generally speaking, the "S" stands for "Short Wave Length" and "L" stands for "Long Wave Length".
LX fibre - e.g. 1GBASE-LX / 1000BASE-LX is available in 50 μm and 62.5 μm as multi-mode fibre (mmf) supporting about 550 meters distance at 1300 nm wavelength. Distances of 2..10 km are possible in case of single-mode fibre (smf).
SX fibre - e.g. 1GBASE-SX / 1000BASE-SX is available in 50 μm and 62.5 μm as multi-mode fibre supporting about 250 meters distance at 850 nm wavelength. This wavlength allows for the use of LED transmitters, which are cheaper available then the normally used laser components.
FX fibre refers to the 100BASE-FX fast ethernet standard. This fibre type is the long wavelength optics fibre type for 100Mbps transmission systems.
This brief explaination should soon be extended. Fell free to add your knowledge to this post.
