FOC transmitters

FOC transmitters

When signals are transmitted via fiber optic cables (FOC) instead of copper cables, FOC transmitters from Johannes Huebner Giessen code the active parallel signals 0°, 90°, reference pulse and LED check and transmit them to the decoder on the switchboard via a fiber optic cable. Utilizing the FOC transmitters it is possible to achieve high data transmission rates even with long lengths of cable. Transmission reliability is assured thanks to electrical isolation. It is possible to select HTL and/or TTL as output blocks. Optional FOC cable break monitoring is available to increase system reliability.
