Network topology for bidirectional data transmission in passive network - has cable branch points at beginning and end of network dividing central device data lines into local device data lines

摘要

The network topology allows bidirectional data transmission between a central communication device (SKE) and a number of local communication devices (LKE), using separate transmission and reception data lines. Two spaced cable branch points at the beginning and end of the network allow the transmission and reception data lines of the central communication device (ZKE) to be divided into corresp. transmission and reception data lines for the local communication devices. Electrical or optical fibre data lines,or a combination of both may be used. ADVANTAGE - Reduced cabling lengths for reducing propagation time correction.
