Patent number: 11533106Abstract: Methods and systems for automated health assessment of fiber optic links of a fiber optic communication system are described. Tables are used to describe the fiber optic links, including access addresses to communication modules used in the links. Telemetry data representative of operation of the communication modules can be read via the access addresses into a central station. OTDR/OFDR measurement data of fiber optic segments used in the links can be read via the access addresses into the central station. The telemetry and/or OTDR/OFDR measurement data can be used by the central station for comparison against reference data to assess health of the links. The communication modules locally and continuously capture the telemetry data to detect transient events that may be the result of tampering of the links.Type: GrantFiled: May 16, 2022Date of Patent: December 20, 2022Assignee: ULTRA COMMUNICATIONS, INC.Inventors: Joseph F. Ahadian, Vahid Nazer, Sandra Skendzic, Charles B. Kuznia, Richard J. Weiss

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

Patent number: 10234358Abstract: An optical time domain reflectometer (OTDR) system with an integrated high speed optical modulator is capable of operating at a speed similar to the OTDR pulse width to improve the measurement resolution and reduce the time required to acquire a high dynamic range OTDR measurement over existing approaches. ASICs can be used to control the modulator and generation of pulses. The high-speed optical modulator enables high resolution single-photon OTDR measurement by blocking out all return light except from the region of fiber under examination.Type: GrantFiled: April 11, 2018Date of Patent: March 19, 2019Assignee: Ultra Communications, Inc.Inventors: Joseph F.

Patent number: 9465176Abstract: A fiber optic transceiver that is compatible with packaging into standard semiconductor packages and for SMT packaging, using materials and fabrication procedures that withstand solder assembly processes. The SMT package can have electrical contacts on the exterior of the package for creating electrical conduits to a substrate, such as a PCB, interposer, or circuit card within a larger assembly. The fiber optic transceiver can be of a non-SMT package configuration, being formed with electrical connection technology that allows direct connection to a substrate with electrical wiring, such as a PCB, interposer, or circuit card within a larger assembly. The fiber optic transceiver may have solderballs, metal posts or other electrical conduit technology that allows direct electrical connection to the substrate.Type: GrantFiled: April 11, 2013Date of Patent: October 11, 2016Assignee: ULTRA COMMUNICATIONS, INC.Inventors: Richard J.

Patent number: 9151916Abstract: A device structure and system for connecting optical waveguides to optical transmit and receive components is described. The structure is made of two parts. The lower part contains active optoelectronic components, such as lasers and photodetectors, and optical lenses. The lower part can be assembled by steps of aligning and bonding planar components. The upper part contains optical waveguides and lenses for coupling light into and out of the waveguides. The top part is mechanically connected to the lower part to form a mechanically sound connection. The lens system provides some tolerance to mis-alignment between the top and bottom parts. The system has features that enable fiber optic components to operate and survive in harsh environments, particularly large temperature extremes.Type: GrantFiled: May 15, 2012Date of Patent: October 6, 2015Assignee: Ultra Communications, Inc.Inventors: Richard J.
