AS-i signal transmission via fibre optics.

Published on : Tuesday 30-11--0001

ifm's new AS-i fibre optic repeater enables AS-Interface signal transmission via an optical medium and vice versa. Cable lengths in AS-i networks can now be considerably extended. Moreover, mixed operation of AS-i flat cable and fibre optics is possible.

Every AS-i fibre optic repeater has two independent channels that consist of a transmitting and a receiving element. They are electrically isolated and convince by their high operational reliability. The AS-Interface system provides the voltage supply for these units. This further development has been integrated in the new SmartLine housing with two terminals.

Optical transmission means there is no interfering radiation, nor are there any ground problems. Fibre optic transmission systems exclude any EMC risk, as a matter of principle. As to distance related losses due to inductances, capacities and resistances (as is the case with copper cables for example), they do not occur either. This guarantees high operational reliability and increases machine uptime. Using the new AS-i fibre optic repeater allows for additional fibre optic network topologies (line topology, star topology).
