Difference between multimode and singlemode
transmissions
The devices of the FIBREVision series are either available as a variant for multimode
or singlemode fibres:

Multimode fibres enable users to bridge a maximum distance of 550 metres.
By applying these fibres, the signals are transmitted through many different opti-
cal path lengths. Thus, the signal is influenced. Multimode fibres are therefore not
suited for bridging great distances.
 Singlemode fibres enable users to bridge a maximum distance of 10 kilometres.
In contrast to multimode fibres, multipath transmission is omitted. By applying
these fibres, the signals are transmitted through one light wave only. Due to their
smaller core diameter, applying these fibres proves to be more difficult.
