Abstract: An improved electro/mechanical connector through which multi-media electrical signals are transported includes a first port with resilient contact tongues, a second port for supporting a coaxial assembly and a third port coupled to a circuit module which receives the multi-media electrical signals on an input terminal splits the multi-media electrical signals into broadband signals which are routed to the coaxial assembly and baseband signals which are routed to the first port. The circuit module also receives broadband signals and baseband signals from the coaxial assembly and first port respectively combines them into the multi-media signals which are outputted on the input terminal.

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.

Abstract: Described is a communications system for transmitting baseband and broadband signals simultaneously. The system is ideally suited for interconnecting different types of data terminal equipment (DTE) within a building or limited geographical area. The system includes a backbone communications network formed from a plurality of independent communications systems. Each of the plurality of independent communications systems is dedicated to transmit either the baseband signals or the broadband signals. A Filter Coupler (FC) network combines and separates the two different type of signals at the distribution level. One embodiment of the FC includes a filter network coupled in tandem with a high frequency transformer. In an alternate embodiment the FC includes a balun transformer coupled to a directional coupler transformer.
