ABSTRACT:
A communications system including an optical communications channel, a wire distribution network and an interface assembly for coupling the optical communications channel to the wire distribution network. The interface assembly includes circuit arrangement having a transmitter section and a receiver section. The transmitter section receives high speed (say 100 mbits per sec) data signal from the optical channel, equalizes the data signal, reduces the signal amplitude, filters the common mode signal components and delivers the data signal to the wire distribution network. Data from the wire distribution network is filtered in the receiver section to remove common mode signal components, terminated, amplified and delivered to the optical channel. By doing all this, an optimum transmit signal is provided which best suits EMI requirements as well as a superior signal to noise response. The EMI characteristics of the system fall within the FTC guideline.
