Patent number: 11761828Abstract: Methods and devices for a single wavelength fiber optic sensor system are described. Sensing is based on relative shift in spectral responses of two co-located fiber gratings (FBGs) within a fiber optic cable and measured at one measurement wavelength. Under a range of conditions of interest, the shift in spectral responses maintains the measurement wavelength within respective slopes of the spectral responses. A normalized difference in reflected power is used to desensitize the measurement from any variation in power of the single laser power and/or in loss through the fiber optic cable. Several pairs of co-located FBGs may be used within the same fiber optic cable, each pair used for sensing at a corresponding location. An OTDR system couples light pulses at the measurement wavelength to the fiber optic cable, and measures amplitudes and timing of corresponding reflected light pulses to perform the normalized difference.Type: GrantFiled: April 9, 2021Date of Patent: September 19, 2023Assignee: ULTRA COMMUNICATIONS, INC.Inventors: Joseph Farzin Ahadian, Sandra Skendzic, Man W. Wong, Charles B. Kuznia

Patent number: 10935732Abstract: A protective assembly method using a transparent layer within the fiber interconnect system aids in optical coupling by preventing an air gap from forming between the fiber cores within a connector. A fiber protection device made of a thin transparent film, which includes an adhesive layer, is applied over the fiber end-faces at the connector interface, the film having characteristics which allows it to conform to the fiber end and minimize coupling loss between fibers. According to one aspect, the film is part of a cartridge that provides structural support for the film to facilitate application of the fiber protection device. The film may be divided by perforate patterns that define one or more fiber protection devices formed by the film. The assembly method can include usage of an applicator base plate upon which the cartridge is mounted. According to another aspect, the film may be part of a single-use disposable pod for application of a single fiber protection device.Type: GrantFiled: February 20, 2020Date of Patent: March 2, 2021Assignee: Ultra Communications, Inc.Inventors: Man W. Wong, Joseph Farzin Ahadian, Howard Arthur Lenos

Patent number: 10712508Abstract: A protective assembly method using a transparent layer within the fiber interconnect system aids in optical coupling by preventing an air gap from forming between the fiber cores within a connector. A thin transparent film (or with adhesive) is placed over the fiber end-faces at the connector interface, the film having characteristics which allows it to conform to the fiber end and minimize coupling loss between fibers. The film is sized to fit connectors faces and can be temporary, being replaced with each installation. A coating can also applied to the connector surface, providing a similar effect, as well as structurally enhancing the connector surfaces.Type: GrantFiled: November 16, 2018Date of Patent: July 14, 2020Assignee: Ultra Communications, Inc.Inventors: Charles B. Kuznia, Richard J. Pommer, Joseph F. Ahadian, Richard T. Hagan, Man W. Wong

Publication number: 20030109142Abstract: An integrated photodetector means for controlling the output of a light source, where the control means is a photodetector formed on a silicon-on-insulator substrate. The integrated photodetector senses the optical power from the light source and provides an electrical feedback signal which can be used to adjust the DC bias levels of the light source control driver circuit. The approach readily lends itself to large arrays of light sources bonded to silicon-on-sapphire driver circuits and is especially suitable for controlling light sources such as VCSELs in arrays such as are found in communications systems.Type: ApplicationFiled: June 24, 2002Publication date: June 12, 2003Inventors: James S.
