Patent number: 10845534Abstract: A multi-mode optical fiber includes a glass center for conducting fundamental and high order modes of light waves, the high order modes including a first desired group of high order modes and a second undesired group of high order modes. A cladding surrounds the glass center, the glass center and cladding forming a core. A trench within the cladding surrounding the glass center reflects the first and second groups of high order modes into the core. The multi-mode optical fiber is constructed with a pressure applying element thereover that applies continuous pressure to the core, along the length of the multi-mode optical fiber, such that the at least the first group of desired high order modes are permitted to be transmitted through the core and where the second group of undesired high order modes are suppressed.Type: GrantFiled: August 29, 2019Date of Patent: November 24, 2020Assignee: BERK-TEK LLCInventors: Paul Michael Good, Rakesh Sambaraju

Patent number: 10797797Abstract: The present arrangement replaces passive components of a multi-mode fiber optic channel, such as a typical prior art cassette (i.e. connectors & short lengths of fibers) with active cassettes that have components therein that receive the optical signal from a first transmitting transceiver, convert the signal to an electrical signal, route that signal appropriately within the cassette and re-send an optical signal out from the opposite of the cassette into the infrastructure harness. This results in a localized optical signal boost at a mid-channel location.Type: GrantFiled: March 31, 2017Date of Patent: October 6, 2020Assignee: NEXANSInventors: Rakesh Sambaraju, Michael Good

Patent number: 10741304Abstract: A cable is provided for detecting tampering thereof. The cable has at least two copper signal cables, at least one hollow buffer tubes located abutting the two copper signal cables, an inner jacket, an armor, and at least one loose tube optical fiber sensor element disposed within the cable in a configuration that subjects the optical fiber sensor to external conditions. The at least one loose tube optical fiber sensor element is located between and abutting at least one of the copper signal cables and the at least one adjacent hollow buffer tube. The at least one loose tube optical fiber sensor element is configured attenuate under changes in the external conditions.Type: GrantFiled: June 20, 2019Date of Patent: August 11, 2020Assignee: NEXANSInventors: David Keller, Donald Stevens, Pritesh Majmundar, Norman Andrew Punch, Jr., Rakesh Sambaraju, Dan Rouse, Randie Yoder

A cladding surrounds the glass center, the glass center and cladding forming a core. A trench within the cladding surrounds the glass center reflecting the first and second groups of high order modes into the core. An acrylic layer surrounds the core. A buffer coating of polymer surrounds the acrylic layer and the core. The buffer coating is a pressure extruded polymer, where the buffer coating retains at least some of the pressure from the pressure extrusion and applies continuous pressure to the acrylic layer and the core therein, along the length of the fiber, such that the at least the first group of desired high order modes are permitted to be transmitted through the core and where the second group of undesired high order modes are suppressed.Type: GrantFiled: August 31, 2018Date of Patent: November 5, 2019Assignee: NEXANSInventors: Paul Michael Good, Rakesh Sambaraju

Patent number: 9979444Abstract: Hybrid intra-cell/inter-cell remote unit antenna bonding in multiple-input, multiple-output (MIMO) distributed antenna systems (DASs), and related components, systems, and methods. The MIMO DASs are capable of supporting distributed MIMO communications with client devices. To provide enhanced MIMO coverage areas, hybrid intra-cell/inter-cell remote unit antenna bonding is employed. For example, if a client device has acceptable MIMO communications signal quality with MIMO antennas within a single remote unit, intra-cell bonding of the MIMO antennas can be employed to provide MIMO coverage for MIMO communications, which may avoid power imbalance issues that would result with inter-cell bonded MIMO antennas. However, if a client device has acceptable MIMO communications signal quality with MIMO antennas in a separate, neighboring remote unit(s), inter-cell bonding of the MIMO antennas can be employed to provide MIMO coverage for MIMO communications.Type: GrantFiled: April 12, 2017Date of Patent: May 22, 2018Assignee: Corning Optical Communications LLCInventors: Jacob George, Anthony Ng'oma, Rakesh Sambaraju
