Abstract: A chassis and circuit modules for controlling electromagnetic interference in high-speed digital transceiver circuits. The impedance between a reference ground point and the transceiver circuits and a chassis wall through which the transceiver circuit signals pass is kept very low by intimate physical contact between a conductive bulkhead section of the module and the ground plane used by the transceiver. In particular, there is disclosed an arrangement whereby a plurality of modules are placed adjacent one another in a cabinet. Each of the modules contains a conductive bulkhead section or handle, which engages other adjacent bulkhead sections, and which may have an input/output connector mounted thereon. Each module also has a printed circuit board mounted to the bulkhead section so that a forward-circuit reference path reserved for use by transceiver circuits is positioned adjacent the connector and electrically connected to both the connector and the front section via a low impedance path.
