Abstract: An air-gap HCF connector termination method and connector assembly for factory and field connector assembly termination for patch cables and trunk cables made from HCF, where in multitude of mechanisms can facilitate air-gap between the first and second HCF fiber end-faces, comprising preparing the HCF end-faces using appropriate cleaving methods including mechanical, ultrasonic and laser cleaving, such that the air-gap separation between first and second HCF's can be anywhere between 0.5-100 microns, where reflection at the connector interface is low with RL>35 dB, due to HCF propagation mode effective index matching with index of air.

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%.

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 low latency free-space optical data communication channel has at least one optical collimator for transmitting an optical communication signal in the form of a parallel beam across a free-space channel. The input of the collimator includes a connectorized optical fiber pigtail for connecting said collimator to a glass optical fiber carrying the signal to be transmitted across the free-space channel. The optical beam propagates in free space along the longitudinal axis of a raceway, which is at least partially enclosed. The second optical collimator located at the distant end of said raceway, is positioned to receive the free-space optical communication signal. The received signal is focused into a second optical fiber pigtail at the output side of the collimator, thereby resulting in a pigtailed free-space low latency optical channel link.

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: 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.
