Abstract: A test apparatus has at least one optical source, a high-speed photodetector, a microcontroller or processor, and electrical circuitry to power and drive the at least one optical source, photodetector, and microcontroller or processor and for measuring the frequency response of a multimode optical fiber under test. The test apparatus can utilize an optical pulse waveform with a light adapter to measure of the channel under test. It can also uses a correction method to de-embed a chromatic bandwidth of the source from the encircled flux modal chromatic bandwidth. The correction method can use correction functions obtained for different type of VCSELs to estimate the optical channel bandwith when used with VCSEL transceivers.

Abstract: A system for implementing Bi-Di fiber optic LAN has a plurality of optical channels being transmitted over a same optical fiber by using wavelength division multiplexing and wherein at least one of the optical fiber channels have bi-directional transmission. The system also has an access network side located in at least one of a zone distribution area or zone box, access network side cabling distributed across diverse physical distances with individual cable runs; and optical Ethernet transceivers that do not require the high transmitting optical power and high receiver sensitivity typically.

Abstract: Various implementations of visual inspector attachments for fiber connector cleaners are disclosed. The example fiber optic inspection module includes a camera to capture an image of an end-face, a light source to illuminate the end-face, and a first mirror that reflects light from the light source to the end-face and includes a fixed point that allows the first mirror to pivot. Alternatively, an example fiber optic inspection module includes a camera to capture an image of an end-face, a light source to illuminate the end-face, and a first mirror that reflects light from the light source to the end-face and the first mirror moves in an upward direction.

Abstract: A test apparatus has at least one optical source, a high-speed photodetector, a microcontroller or processor, and electrical circuitry to power and drive the optical source, high-speed photodetector, and microcontroller or processor. The apparatus measures the frequency response and optical path length of a multimode optical fiber under test, utilizes a reference VCSEL spatial spectral launch condition and modal-chromatic dispersion interaction data to estimate the channels total modal-chromatic bandwidth of the fiber under test, and computes and presents the estimated maximum data rate the fiber under test can support.

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.
