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.

Abstract: A multi-channel, multi-port optical tap coupler with an alignment base element, a pair of sub-assemblies located at opposite ends of the alignment base element, focusing elements located next to each sub-assembly, and an optical filter adjacent to, and in-between the focusing elements is described. The first sub-assembly has an array of waveguides with each waveguide having a radial offset and an azimuthal position with respect to a center axis of the array. The first array includes transmission waveguides and receiving waveguides and each receiving waveguide has a corresponding transmission wave guide that is separated by an azimuthal angle of 180 degrees. The second sub-assembly has a second array of waveguides including a wave guide having the same radial offset and the same azimuthal position for each of the transmission wave guides of the first array.

Abstract: An optical interconnection assembly for a Spine-and-Leaf network is disclosed. The optical interconnection assembly 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. An array of simplex fiber optic cables in said interconnection assembly serve 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 network Spine-and-Leaf interconnections and the ability to scale-out the network by installing additional assemblies, Leaf switches, and Spine switches.

Abstract: An apparatus having at least two user interfacing I/O data communication transceivers. The I/O transceiver utilizes either electrical or optical signaling based on user preference with each I/O transceiver being electrically connected back-to-back to a WDM transceiver in the apparatus. The optical media dependent interface of each WDM transceiver has a uniquely specified wavelength and optical ports of the WDM transceivers are connected to the corresponding wavelength ports of a WDM device. The discrete optical wavelengths are multiplexed or demultiplex onto a duplex pair of optical fibers by means of the WDM device in order to convert the interfacing I/O signals to the appropriate optical wavelengths to facilitate pre-configured WDM optical communications.

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 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.
