The Tranceiver "K line to OWG"1)

The bi-directional K line is splitted up into two single signals (transmit and receive). These two signals are now fed via optical fibres.

1) OWG: Optical wave guide
By replacing the copper wired K line with OWG the immunity to EMC could be increased another time. Also, there are less reactions of test set-up to the test result.
