** [[Coarse wavelength-division multiplexing]] (CWDM) and [[dense wavelength-division multiplexing]] (DWDM) transceivers at various wavelengths achieve various maximum distances. CWDM and DWDM transceivers usually support link distances of 40, 80 and 120&nbsp;km.

They are not compatible with (or rather: do not have equivalents for) [[Fibre Channel]] or SONET. Unlike most non-SFP, copper 1000BASE-T ports integrated into most routers and switches, 1000BASE-T SFPs usually cannot operate at [[100BASE-TX]] speeds.
