Abstract: Various implementations of fiber optic inspection tools with integrated cleaning mechanisms are disclosed. The fiber optic inspection and cleaning tool includes a housing, a cleaning system and an imaging system. The cleaning system includes a pay-off reel, a take-up reel, a spindle and a cleaning tape that travels off the pay-off reel, around the spindle, and onto the take-up reel. The imaging system includes a camera and a light source. The camera, spindle, and cleaning tape are aligned along a visual axis. The pay-off reel, take-up reel, camera and light source are all located within the housing.

Abstract: Embodiments of the present invention provide an improved method of determining splice losses of mechanically terminated optical connectors in the field, without the need of terminating both sides of the fiber link. Embodiments of the present invention also provide means for improving the quality of mechanical splices as utilized in pre-polished fiber optic connectors for terminating single-mode and multimode optical fibers in the field.

Abstract: Various implementations of systems and methods for insertion loss estimation are disclosed. The system for insertion loss estimation includes a first filter, a focusing component, and a digital micromirror device (DMD). The first filter, the focusing component, and the DMD are in parallel with an optical fiber connector. Additionally, the system includes an optical concentrator and a photodetector device. A first face of the optical concentrator is facing towards the DMD, and a second face of the optical concentrator is facing the photodetector device. Both the photodetector device and the optical concentrator are in parallel.

Abstract: Methods for estimating the Effective Modal Bandwidth (EMB) of laser optimized Multimode Fiber (MMF) at a specified wavelength, λS, based on the measured EMB at a first reference measurement wavelength, λM. In these methods the Differential Mode Delay (DMD) of a MMF is measured and the Effective Modal Bandwidth (EMB) is computed at a first measurement wavelength. By extracting signal features such as centroids, peak power, pulse widths, and skews, as described in this disclosure, the EMB can be estimated at a second specified wavelength with different degrees of accuracy. The first method estimates the EMB at the second specified wavelength based on measurements at the reference wavelength. The second method predicts if the EMB at the second specified wavelength is equal or greater than a specified bandwidth limit.

Abstract: Examples disclosed herein illustrate systems and methods to determine and evaluate the quality of mechanical splices of optical fibers using insertion loss estimation. In at least some of the disclosed systems and methods, an optical fiber termination system may include a reference fiber coupling a light source and a stub fiber of a fiber optic connector, a digital camera sensor and lens to capture images of scattered light emanating from a portion of the fiber optic connector and a portion of the reference fiber both in a field of view (FOV) of the digital camera sensor, and a processor. The processor may analyze digital images of scatter light emitted from at least a portion of the fiber optic connector and the reference fiber to estimate insertion loss at the fiber optic connector.

Abstract: The present invention relates in general to communication systems, and more specifically towards methods, systems, and devices that help improve transmission rates and spectral efficiency of intensity modulated (IM) or power modulated channels utilizing multi-level pulse amplitude modulation PAM-M. In an embodiment, the present invention used an iterative algorithm to open the eyes of an eye diagram in a relatively short number of steps. The algorithm, which may not require previous characterization of the channel, utilizes pseudo-random sequences, such as PSBS15 or PRQS10, and adaptive non-linear equalizers to optimize the pre-distortion taps.
