摘要：The circuit provides signals with a NRZI coding for data transmission via anoptical conductor bus (LWL-B), interconnecting a main station and a number of sub-
stations (S1). Each sub-station has an inverter (IV1), a decoder (DEK) associated with areceiver (EMP) and a coder (KOD) associated with a transmitter (SEN). The signals passingthrough the sub-station are inverted and fed to the output (EOW) via a coupler (EK) forcombining with the output signals of the coder. The NRZI output of the latter is coupledto both inputs of an Exclusive-OR gate of the coder, directly and via a delay (DV), with thedecoder providing a level change at the output in response to each input pulse via a i-bitcounter (EZ).
