A circuit board module includes a circuit board defining a top side, a bottom side and holes extending through the circuit board between the top and bottom sides. The module further includes a component mounted to a portion of the circuit board, and an EMI shield assembly configured to provide EMI shielding on the circuit board. The EMI shield assembly includes a top shield and a bottom shield. The top and bottom shields are configured to substantially enclose the portion of the circuit board and the component to provide EMI shielding when (i) contacts of the top shield insert into the holes defined by the circuit board in a first direction from the top side toward the bottom side, and (ii) contacts of the bottom shield simultaneously insert into the same holes defined by the circuit board in a second direction from the bottom side toward the top side.

EMI shielding techniques using multiple EMI shields which share the same circuit board holes

A shelf assembly and system, which reduces the potential for accidental disruption of service or damage to neighboring transmission elements in a telecommunications network. The present invention operates to guide the transmission elements or fiber cables to and/or from a mounting position, and in or out from either side of electrical and/or optical telecommunications equipment. Fiber cables coupled at the mounting positions can be directed through reversible and removable fiber channels. Each fiber channel has a smooth surface and a radius of curvature, which provides an appropriate bend radius for guiding, routing, or bending the fiber cables into a fiber trough.
