OM1 to OM4 fibre optic cables can only send wavelengths of 850 nanometres. As a result, the data can only flow in one direction. Thus, at least two fibres are always needed, one for sending and one for receiving. This applies at least to data rates of up to ten gigabits per second. At higher data rates, such as 40 to 100 gigabits, the data streams are split into packets of ten during transmission and then combined again at the receiver. The technical term for this is "parallel optical transmission". Therefore, for the transmission of 40 gigabits, four fibres are needed for transmission and just as many for reception, i.e. a total of eight. For 100 gigabit, 20 fibres are used accordingly. In an OM5 cable, the techniques Short Wave Division Multiplexing (SWDM) and Wideband Multimode Fibre (WBMMF) are combined. Older multimode fibres are optimised for the wavelength range of 850 nanometres. Using SWDM technology, wavelengths.
