Embodiment Construction

[0022] Reference will now be made to the drawings, which help illustrate various pertinent features of the invention. Although the invention will now be described primarily in connection with a DC power filter for a telecommunications rack, it should be clearly understood that the invention may be applied to other applications where it is desired to reduce noise passing through the electrical circuit. In this regard, the following description of a DC power filter for a telecommunications rack is given for purposes of illustration and description. Furthermore, the description is not intended to limit the invention to the forms disclosed herein. Accordingly, variations and modifications commensurate with the following teachings, and skill and knowledge of the relevant art, are within the scope of the invention. The embodiments described herein are further intended to explain known ways of practicing the invention, and are intended to enable others skilled in the art to utilize ...

Abstract

Generally, a DC power filter and its associated components are presented herein. The DC power filter may operate in a telecommunications chassis between one or more electrical sources and one or more loads. A common mode noise shunt may be included to shunt noise from more than one of the electrical sources or loads together. Additionally, the DC power filter may include protection circuitry that is coupled to more than one of the electrical sources. The protection circuitry may include a combination of diodes and other transient voltage suppression devices.

Description

[0001] Cross References to Related Applications [0002] This application claims priority under 35 U.S.C. §119 to U.S. Provisional Application 60 / 865,334, filed November 10, 2006, entitled "Power Filter," which is hereby incorporated by reference in its entirety . Background technique [0003] Often, modern telecommunications equipment is grouped together in the same rack, enclosure or building. For example, in a base station of a cellular telecommunication system, there may be a small building housing multiple types of telecommunication equipment grouped together in one or more telecommunication racks or cabinets. A central office (CO) may comprise a larger building with multiple racks of telecommunications equipment and telecommunications racks, each rack containing multiple telecommunications circuit cards that may perform different functions. In each of these and other situations, the telecommunications equipment in a single building can all be powered by the same power ...
