Abstract: An apparatus having input and output ports using a plurality of optical connector adapters, wherein the fiber connections can follow a specific mesh pattern has a plurality of fibers inside the apparatus. The fibers pass through at least one mandrel and are designed to produce a leakage in the transmitted light from each fiber of least −30 dBm, wherein the fiber buffer of fibers around the mandrel are partially stripped in at least one section. The apparatus also has an imaging system consisting of at least a lens, camera sensor and an optical filter are placed in proximity to the fiber striped section wherein the optical filter has spectral properties tuned or partially tuned to the operational wavelength of the network and the optical filter is placed in the light path before the camera sensor.

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: An optical interconnection assembly and method for the deployment and scaling of optical networks employing Spine-and-Leaf architecture has Spine multi-fiber optical connectors and Leaf multi-fiber optical connectors. The Spine optical connectors of the interconnection assembly are optically connected to multi-fiber connectors of Spine switches via Spine patch cords. The leaf multi-fiber connectors are optically connected to Leaf multi-fiber connectors of Leaf switches via Leaf patch cords. A plurality of fiber optic cables in said interconnection assembly serves to optically connect every Spine multi-fiber connector to every Leaf multi-fiber connector so that every Spine switch is optically connected to every Leaf switch. The optical interconnection assembly facilitates the deployment of network Spine-and-Leaf interconnections and the ability to scale out the network by using simplified methods described in this disclosure.

Abstract: A low latency free-space optical data communication channel has at least two opposing optical collimators for transmitting an optical communication signal in the form of a parallel beam across a free-space channel. The input of the collimators are multi-core optical fibers. Multiple cores of the multi-core optical fibers are positioned at the focal point of the two opposing optical collimators. The optical collimators image the communications signals in each of the cores of the multi-core fibers into the corresponding cores of the opposing multi-core fibers.

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-embeed 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 bandwidth when used with VCSEL transceivers.
