摘要： Systems and methods for performing a Control Plane Triggered (CPT) Optical Protection Switching (OPS) policy are provided. A method, according to one implementation, includes performing a first route switching procedure for switching routes between an originating node and a terminating node. The first route switching procedure is configured to operate at a first priority level according to an Optical Protection Switching (OPS) policy. The method also includes performing a second route switching procedure for switching routes between the originating node and the terminating node. The second route switching procedure is configured to operate at a second priority level according to a second protection policy, wherein the second priority level is higher than the first priority level. Also, the method includes reverting back to a home path according to the first route switching procedure after one or more faults, defects, or degradations have been cleared from the home path.

摘要： Systems and methods include causing transmission of one or more shaped Amplified Spontaneous Emission (ASE) signals, from an ASE source (70), on an optical fiber (58, 60); obtaining received spectrum of the one or more shaped ASE signals from an optical receiver (68) connected to the optical fiber (58, 60); and characterizing the optical fiber (58, 60) based in part on one or more of a nonlinear skirt and a center dip depth in the received spectrum of the one or more shaped ASE signals. The one or more shaped ASE signals can be formed by the ASE source (70) communicatively coupled to a Wavelength Selective Switch (WSS) (62) that is configured to shape ASE from the ASE source to form the one or more shaped ASE signals with one or two or multiple peaks and with associated frequency.

摘要： Systems and methods are provided for utilizing polarization parameters obtained from an optical network to determine vibrations in optical fibers using coherent optics equipment and machine learning techniques. A method, according to one implementation, includes the step of obtaining a time-series dataset that includes measurements of polarization characteristics of light traversing an optical fiber of an optical network. The method also includes the step of detecting vibration characteristics of the optical fiber based on the time-series dataset. In some implementations, the time-series dataset may be a multi-variate dataset and the polarization characteristics may be related to transients in a State of Polarization (SOP). The SOP, for example, may be represented by an amplitude and a phase of an electric field vector and may be defined as having one of a linear polarization, elliptical polarization, and circular polarization.

摘要： Systems and methods are provided for enhancing techniques for provisioning optical channels to allow optical networks to operate in an optimal fashion. A method, according to one implementation, includes receiving measured optical performance parameters of a plurality of optical channels transmitted over an optical spectrum between two network elements in an optical line system; determining a performance profile of the optical spectrum based on the measured optical performance parameters; translating the performance profile into configuration information for the two network elements; and causing provisioning of the two network elements based on the configuration information. The measured optical performance parameters are for one or more unassigned optical channels on the optical spectrum, with the measured optical performance parameters being made on one or more optical modems.

摘要： A first (second) electrical input port receives a first (second) drive signal. A first (second) transmission line is configured to propagate a first (second) electromagnetic wave over at least a portion of a first (second) optical waveguide arm of an MZI to apply an optical phase modulation. A drive signal interconnection structure is configured to provide a first electrical connection between the first electrical input port and an inner electrode shared by the transmission lines, and a second electrical connection between the second electrical input port and respective outer electrodes of the transmission lines; and is configured to preserve relative phase shifts between the drive signals. An impedance associated with a first electric field distribution between the inner electrode and a first of the outer electrodes is substantially equal to an impedance associated with a second electric field distribution between the inner electrode and a second of the outer electrodes.

摘要： An optical modulator includes a waveguide core; a first transition zone located between a first side of the waveguide core and a first electrical contact region; and a second transition zone located between a second side of the waveguide core and a second electrical contact region, wherein one or more of the first transition zone and second transition zone has a variable thickness. The variable thickness is confined to the one or more of the first transition zone and second transition zone. The variable thickness removes a portion of the highly doped first transition zone and the highly doped second transition zone thereby reducing contact resistance.
