Abstract

A twinaxial fan-out box (FOB) is a one-to-seven repeater with the capability of increasing cabling distance from a host computer to each work station port with twinaxial cable. The FOB provides work station port noise isolation through a demultiplexer, and provides that a work station can be removed or added to the system while not disrupting any other work station. The FOB removes the cost and topographic restrictions inherent in the implementation of a multidropped single-layer network and the distance limitations of twinaxial cabling. The FOB is capable of driving communication signals to a total of 10,000 feet from the host computer to a work station. Fig. 1 illustrates an overview of a FOB 1 of a 1-to-7 port repeater.
