Patent number: 11902142Abstract: A LAN cable conductor validation system includes controllable relays in-line with a portion of the twisted pair wires of the Ethernet cables. By temporarily open circuiting some of the Ethernet cable twisted pairs a drop in transmission speed can be detected for an active network component. This allows the active component's MAC address to be verified at a given physical location within the cable conductor network system.Type: GrantFiled: November 24, 2020Date of Patent: February 13, 2024Assignee: NFLEXON, LLCInventors: Richard Y. Mei, George W. Brooks

Patent number: 11329723Abstract: An O-band optical communication system includes a transmitter, a receiver, and an optical fiber system coupled between the transmitter and the receiver. The optical fiber system includes at least a first fiber segment, with a positive dispersion-wavelength gradient and a first zero dispersion wavelength, coupled in series to a second fiber segment, with a negative dispersion-wavelength gradient and a second zero dispersion wavelength. When an optical signal propagating along the first fiber segment has a wavelength shorter than the first zero dispersion wavelength and experiences negative dispersion, at least partial positive dispersion compensation is provided by propagation along the second fiber segment. When light of the optical signal propagating along the first fiber segment has a wavelength longer than the first zero dispersion wavelength and experiences positive dispersion, at least partial negative dispersion compensation is provided by propagation along the second fiber segment.Type: GrantFiled: October 23, 2020Date of Patent: May 10, 2022Assignee: COMMSCOPE TECHNOLOGIES LLCInventors: Earl Ryan Parsons, Richard Y.

Patent number: 9696495Abstract: An optical tap includes a support with a first port facing a first ferrule supporting a first fiber along a first axis. A beamsplitter is connected to the support and intersected by the first axis. A second port is fastened to the support and facing a second ferrule supporting a second fiber along a second axis that intersects the beamsplitter. A third port is fastened to the support and facing a third ferrule supporting a third fiber along a third axis that intersects the beamsplitter, wherein the beamsplitter splits a first light signal from the first port to sends first and second portions of the first signal to the second and third ports, respectively. When the beamsplitter may optionally be configured as a polarizing element and include elements configured to rotate relative to each other to change a ratio of the first and second portions.Type: GrantFiled: June 24, 2015Date of Patent: July 4, 2017Assignee: CommScope, Inc. of North CarolinaInventors: Richard Y.

Publication number: 20140233893Abstract: A multi-core optical fiber has dimensions to be backwards compatible with a conventional, single-core optical fiber of the single-mode or multimode type. In one embodiment, the center core has a diameter, such as 3 to 9 um, 50 um or 62.5 um. Such a multi-core optical fiber can be used in connector envelopes like an LC, SC, ST or an array connector, such as an MTP/MPO connector, and will permit the fiber optic connector to continue supporting conventional transmission using only the central core of the optical fiber. Yet, allow fiber optic networks to be upgraded from supporting conventional transmission to parallel transmission using the multiple cores within the optical fiber at a later date.Type: ApplicationFiled: July 31, 2013Publication date: August 21, 2014Applicant: CommScope, Inc. of North CarolinaInventors: Richard Y.
