Abstract:
1. A telecommunications circuit module, comprising: a printed circuit board including circuitry, wherein the circuitry includes repeater circuitry receiving an input signal, recovering data and clock information from the input signal, and creating an output signal repeating the data and clock information, and wherein the input signal is a monitor signal, the repeater circuitry including an amplification portion with a current feedback operational amplifier and a voltage limiting operational amplifier and including a transceiver portion; a metal backplate substantially parallel to but within a different spatial plane from the printed circuit board; a metal shell having a frontplate, a top surface perpendicular to and extending from the frontplate, a bottom surface substantially parallel to the top surface and extending from a side of the frontplate away from the top surface, and a back surface perpendicular to the front plate and the top and bottom surfaces, wherein the top surface, bottom surface, and back surface each has a folded edge that abuts the metal backplate to establish metal to metal contact; and a metal jack holder extending perpendicularly from the printed circuit board and abutting the front plate, top surface, and bottom surface to establish metal to metal contact along a side away from the back surface, and wherein at least a portion of the circuitry is disposed between the frontplate and the backplate and between the metal jack holder and the back surface.
