"Telecommunications Assembly" in Patent Application Approval Process

July 16, 2014



By a News Reporter-Staff News Editor at Telecommunications Weekly -- A patent application by the inventors Krampotich, Dennis (Shakopee, MN); Coan, Jonathan Walter (Savage, MN), filed on October 22, 2013, was made available online on July 3, 2014, according to news reporting originating from Washington, D.C., by VerticalNews correspondents.

This patent application is assigned to ADC Telecommunications, Inc.

The following quote was obtained by the news editors from the background information supplied by the inventors: "Telecommunication cabling systems typically include cabinets that house terminations and connections/interconnections of telecommunication cables. The telecommunication cables can include electrical cable, fiber optic cable, and/or hybrid cable that includes both electrical and optical conductors. The cabinets typically allow terminations of the various cables to be connected, disconnected, and/or reconnected to other terminations of the various cables. In this way, the routing of signals across a telecommunications network can be configured and reconfigured as desired. For example, a trunk cable from a main office of a telecommunications provider or a data center may be branched to various branch cables at the cabinet. Each of the branch cables may then be routed to an end-user or to another cabinet.

"The telecommunications cable can be stored on, delivered on, and deployed by spools. The cable is typically wound on the spool at a factory that produced the cable. Upon delivery to an installation site, the cable can be unwound from the spool and deployed. The cabinet can hold terminations/connectors of the cables that are routed to it."

In addition to the background information obtained for this patent application, VerticalNews journalists also obtained the inventors' summary information for this patent application: "An aspect of the present disclosure relates to a telecommunications assembly having a chassis defining an interior region and a tray assembly disposed in the interior region. The tray assembly includes a tray and a cable spool assembly. The cable spool assembly is engaged to a base panel of the tray. The cable spool assembly is adapted to rotate relative to the tray. The cable spool assembly includes a hub, a flange engaged to the hub and an adapter module. The flange defines a termination area. The adapter module is engaged to the termination module of the flange. The adapter module is adapted to slide relative to the flange in a direction that is generally parallel to the flange between an extended position and a retracted position.

"Another aspect of the present disclosure relates to a telecommunications assembly. The telecommunications assembly includes a chassis that is adapted for connection to a rack. A tray assembly is removably mounted in the chassis. The tray assembly includes a tray, a cable spool rotatably mounted to the tray and a plurality of adapters mounted to the tray. The tray assembly can be inserted into and removed from the chassis as a unit without requiring the cable spool or the plurality of adapters to be detached from the tray. The tray carries the cable spool and the plurality of adapters during insertion and removal.

"Another aspect of the present disclosure relates to a cable assembly. The cable assembly includes a first cable spool. The first cable spool includes a drum having a first axial end and an oppositely disposed second axial end. A first flange is engaged to the first axial end of the drum while a second flange is engaged to the second axial end of the drum. A tray assembly is mounted to an outer surface of the first flange of the cable spool. The tray assembly includes a tray that defines a lateral direction and a front-to-back direction that is generally perpendicular to the lateral direction. A second cable spool is rotatably mounted to the tray. A plurality of adapters is slidably mounted to the second cable spool of the tray assembly. The plurality of adapters is adapted to slide relative to the tray in a direction that is generally parallel to the front-to-back direction.

The telecommunications apparatus includes a tray, a first spool, a plurality of fiber optic adapters, a second spool, and a fiber optic cable assembly. The tray is configured to mount within a housing. The housing is adapted for connection to a telecommunications rack. The tray includes a base having a top side and a bottom side. The first spool is mounted to the tray at a location above the top side of the base. The first spool is rotatable relative to the tray. The fiber optic adapters are carried by the first spool when the first spool is rotated relative to the tray. The second spool is mounted to the tray at a location below the bottom side of the base. The fiber optic cable assembly includes a main cable portion that is spooled about the first spool and is also spooled about the second spool. The main cable portion includes a jacket containing a plurality of optical fibers. The fiber optic cable assembly also includes a broken-out portion where the optical fibers are broken-out from the jacket and incorporated into separate pigtails having connectorized ends that are received within the fiber optic adapters. The connectorized pigtails extend at least partially along a fiber routing path that extends along the top side of the base of the tray from the first spool to the fiber optic adapters. The second spool is mounted to the tray such that the tray rotates in concert with the second spool when the main cable portion of the fiber optic cable assembly is paid out from the second spool. The first spool rotates relative to the tray when the main cable portion of the fiber optic cable assembly is paid out from the first spool.

"Another aspect of the present disclosure relates to a telecommunications apparatus. The telecommunications apparatus includes a tray, a first spool, at least one fiber optic adapter, a second spool, and a fiber optic cable. The tray is configured to mount within a housing that is adapted for connection to a telecommunications rack. The tray includes a base having a top side and a bottom side.

The at least one fiber optic adapter is carried by the first spool when the first spool is rotated relative to the tray. The second spool is mounted to the tray at a location below the bottom side of the base. The fiber optic cable is spooled about the first spool and is also spooled about the second spool. The second spool is mounted to the tray such that the tray rotates in concert with the second spool when the fiber optic cable is paid out from the second spool. The first spool rotates relative to the tray when the fiber optic cable is paid out from the first spool.

"Another aspect of the present disclosure relates to a telecommunications apparatus. The telecommunications apparatus includes a housing, a tray, a first spool, and a fiber optic cable. The housing is adapted for connection to a telecommunications rack. The housing includes a housing body that defines a cross-dimension, a height, and a depth. The cross-dimension is measured in a direction perpendicular relative to the height and the depth. The housing also including flanges for fastening the housing body to the telecommunications rack. The flanges are separated from one another by the cross-dimension of the housing. The tray can be inserted into the housing and removed from the housing. The first spool is mounted to the tray. The first spool is rotatable relative to the tray about an axis of rotation. The first spool includes first and second flanges that are spaced apart along the axis of rotation. The first spool also includes a core aligned along the axis of rotation and positioned between the first and second flanges. The core defines an elongated spooling path that defines a major dimension and a minor dimension. The fiber optic cable is spooled about the elongated spooling path of the core. The first spool rotates about the axis of rotation relative to the tray when the fiber optic cable is paid out from the first spool.
