US 6,824,312 B2 · Telecommunications chassis and module

Abstract

Telecommunications chassis and associated modules for use with the telecommunications chassis are disclosed. Embodiments of the telecommunications chassis include structures such as horizontal channels and/or horizontal surfaces with ridges and/or slots in one surface and slots in ridges of another for receiving edges of modules that mount within the chassis. Other structures of embodiments include divider slots in the horizontal surfaces that receive edges of divider walls to fix the divider walls in place, heat baffle surfaces included within the chassis, and/or cable guides with radius limiters. Module embodiments include structures such as faceplates with angled portions with fiber optic cable connections directed toward the fiber cable's direction of travel. Other module structures include shells that enclose the circuit board and/or provide angled portions with fiber optic cable connections. Module embodiments may also include circuitry for converting electrical signals to optical and optical signals to electrical, and the circuitry may selectively operate at multiple data rates.

A chassis for holding telecommunications cards, comprising:

first and second horizontal surfaces and vertical sidewalls mounted to the first and second horizontal surfaces, the first horizontal surface having a first ridge positioned substantially perpendicular to a longitudinal axis of the vertical sidewalls, the first horizontal surface having a plurality of card slots extending across the first horizontal surface but not across the first ridge, the card slots being substantially parallel to the longitudinal axis of the vertical sidewalls, the second horizontal surface having a first ridge and a second ridge positioned substantially parallel to but spaced from the first ridge, with a plurality of card slots extending across the first and second ridges of the second horizontal surface and substantially parallel to the plurality of card slots of the first horizontal surface.

A chassis for holding telecommunications modules, comprising:

first and second horizontal surfaces;
vertical sidewalls mounted to the first and second horizontal surfaces;
a first cover surface substantially perpendicular to the vertical sidewalls and between the first and second horizontal surfaces, wherein the first cover surface has a first substantially vertical portion, a second portion angled with respect to the first portion, and a third substantially vertical portion, wherein the second portion interconnects the first portion and the third portion;
and
a second cover surface spaced horizontally from the first cover surface and being substantially perpendicular to the vertical sidewalls and between the first and second horizontal surfaces, wherein the second cover surface has a first substantially vertical portion, a second portion angled with respect to the first portion, and a third substantially vertical portion, wherein the second portion interconnects the first portion and the third portion, and wherein an opening to the interior of the chassis is defined by the first cover surface, second cover surface, and first and second horizontal surfaces.
