modular optical fibre telecontrol system Functional description The fibre optic variant of the MFW modular telecontrol system was developed for data transmission on fibre optic cables. The use of optical fibres as transmission medium ensures a robust interference-free transmission over long distances. A separate fibre optic cable is used for each transmission direction. Two versions are available for coupling the different fibre optic cable types: 1. Multimode fibres with 50/125 µm or 62,5/125 µm core/cladding diameter. Wavelength 1300 nm 2. Single mode fibres with 9/125 µm core/cladding diameter....
