Patent number: 9229175Abstract: Fiber optic assemblies and systems for high-speed data-rate optical transport systems are disclosed that allow for optically interconnecting active assemblies to a trunk cable in a polarization-preserving manner. The fiber optic assembly includes at least first and second multifiber connectors each having respective pluralities of first and second ports that define respective pluralities of at least first and second groups of at least two ports each. The first and second multifiber connectors are capable of being disposed so that the at least first and second groups of ports are located on respective termination sides of each ferrule. The fiber optic assembly also has a plurality of optical fibers that connect the first and second ports according to a pairings method that maintains polarity between transmit and receive ports of respective active assemblies. At least one of the first and second groups are optically connected without flipping the fibers.Type: GrantFiled: July 26, 2012Date of Patent: January 5, 2016Assignee: Corning Cable Systems LLCInventors: Ray S. Barnes, John D. Coleman, Alan W. Ugolini

Patent number: 8718436Abstract: Methods and apparatuses for providing secure fiber optic connections are disclosed. In one embodiment, a locking apparatus comprising a locking plate to secure fiber optic connections is disclosed. The locking plate is configured to be attached to a fiber optic adapter panel and adjustably positioned to a selected position such that when a fiber optic connector on the end of a fiber optic cable is connected to a fiber optic adapter on the fiber optic adapter panel, the fiber optic cable is allowed to pass through a cut-out area of the locking plate but a finger portion of the locking plate does not allow the fiber optic connector to pass through the cut-out area. A lock disposed on the locking plate is configured to keep the locking plate in the selected position. The locking apparatus may also be used to securely store unused or unconnected ports of an optical splitter in a separate enclosure, such as a parking lot compartment.Type: GrantFiled: August 30, 2010Date of Patent: May 6, 2014Assignee: Corning Cable Systems LLCInventors: Ray S.

Patent number: 8047727Abstract: A strain-relief assembly for a field-installable fiber optic connector is disclosed, wherein the assembly includes a ferrule holder, an intermediate sleeve, and a crimp sleeve. The ferrule holder back section holds a buffered section of a fiber optic cable, while the ferrule holder front end holds a ferrule and a splice assembly. A stub fiber is held within the ferrule and the splice assembly so as to interface with a section of field optical fiber protruding from the buffered section. The intermediate sleeve engages and generally surrounds a portion of the ferrule holder back section and thus surrounds a portion of the buffered layer. An intermediate sleeve handler may be used to handle the intermediate sleeve and attached the intermediate sleeve to the ferrule holder back section. Stress-relief strands from the fiber optic cable are flared around the outer surface of the intermediate sleeve. A crimp sleeve is placed over the intermediate sleeve to hold the ends of the stress-relief strands in place.Type: GrantFiled: May 12, 2011Date of Patent: November 1, 2011Assignee: Corning Cable Systems LLCInventors: Ray S.

Patent number: 8009959Abstract: Optical interconnection methods for high-speed data-rate optical transport systems are disclosed that optically interconnect active assemblies to a fiber optic cable in a polarization-preserving manner. The methods include defining active-assembly-wise connector ports that connect to active assembly transmit and receive ports, and defining or establishing a pairings method between the active-assembly-wise connector ports. In a first optical interconnection assembly, an active-assembly-wise port is optically connected to a cable-wise port. In the second optical interconnection assembly, the cable-wise port that corresponds to the connected cable-wise port in the first optical interconnection assembly is optically connected to a select active-assembly-wise port as defined by the pairings method. The optical connection process is then repeated from the second to the first optical interconnection assembly. The optical interconnection acts are repeated until all of the active-assembly-wise ports are connected.Type: GrantFiled: June 17, 2009Date of Patent: August 30, 2011Assignee: Corning Cable Systems LLCInventors: Ray S.
