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: A patch cord for transmitting between a single mode fiber (SMF) and a multi-mode fiber (MMFs) has a MMF, SMF, and a photonic crystal fiber (PCF) with a hollow core placed between the SMF and MMF. A mode field diameter (MFD) of the PCF hollow core section is in the range of 16 to 19 microns, the length of the PCF is between 1 cm to 10 cm, the MMF has 50+2 microns core diameter, the SMF has a 6-9 microns core diameter, and the coupling between the PCF mode to the MMF fundamental mode is maximized.

Abstract: A method for evaluating the optical insertion loss of a mechanical splice joint of two optical fibers with a laser source includes, upon initiation by a user, automatically performing the steps of: checking for ambient light, estimating the level of noise by analyzing an area of a sensor that is not illuminated by external sources and setting a noise threshold, checking self-alignment by taking a foreground image of the joint with the laser source turned on and one with it turned off, subtracting the images to obtain a resultant image, setting all pixels with levels below the noise threshold to zero, selecting a region of interest of the joint, computing a centroid and a width of the resultant image based on the region of interest, estimating a tilt and if the tilt is above a certain threshold, compensating for the tilt, and processing the resultant image.

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: A multiport passive photonic light circuit chip has multiple waveguides written in at least two layers on a glass substrate. Some waveguides connect transmitting and receiving ports of an optical channel, some waveguides redirect a fraction of optical signals to some other receiving ports, and waveguides have circular cross-sectional shapes wherein a refractive index contrast is in the range of 0.2% to 2%.
