    Abstract: Systems and methods of providing a bare circuit integrated circuit package with a containment ring are described. The bare circuit integrated circuit package may be provided with a substrate connected to a printed circuit board. An integrated circuit may be connected to the substrate. A stiffener ring that surrounds the integrated circuit may be attached to the substrate. A heat sink may be positioned on the stiffener ring and over the integrated circuit such that there is a space between a top of the integrated circuit and a bottom surface of the heat sink. A thermal interface material may be provided to thermally connect the integrated circuit and the heat sink. A containment ring may be positioned between the stiffener ring and the integrated circuit, the containment ring sized and positioned to prevent pumping and/or displacement of the thermal interface material.

    Abstract: A method is described in which a coherent transmitter transmits a first optical signal having customer data through a fiber optic link. A control signal is provided to the coherent transmitter to cause the coherent transmitter to transmit a second optical signal devoid of customer data. A reflection of the second optical signal is detected via the coherent receiver. Then, a chromatic dispersion of the reflection of the second optical signal is determined and correlated with known parameters indicative of an amount of chromatic dispersion per unit length of the fiber optic link to determine a distance travelled by the second optical signal.

    Abstract: Optical networks, network elements, and methods of use are described herein, including an optical network comprising head-end and tail-end network elements, an optical multiplex section (OMS) connecting the head-end and tail-end network elements, and one or more intermediate line amplifiers in the OMS between the head-end and tail-end network elements. The head-end network element may store first information indicative of a first tilt control section having the head-end and tail-end network elements as endpoints; determine information indicative of a change in topology of the OMS, such as that a first intermediate line amplifier has switched from a non-monitoring to a monitoring mode; and store second information indicative of a second tilt control section having the head-end network element and a new tail-end network element, such as the first intermediate line amplifier.

    Abstract: Disclosed herein are methods and systems for computing a launch power for an optical node by collecting data for an optical network segment and inputting the collected data and first power spectral density values into a machine learning model which are used to compute a first non-linear interference value. A first generalized-optical signal-to-noise ratio value is computed using the computed first non-linear interference value and amplified spontaneous emission values. At least one second generalized-optical signal-to-noise ratio value is computed using at least one second non-linear interference value, computed using at least one second power spectral density values, and the amplified spontaneous emission values. A highest generalized-optical signal-to-noise ratio value is determined by comparing the first generalized-optical signal-to-noise ratio value and the at least one second generalized-optical signal-to-noise ratio value. A launch power is computed using the power spectral density values associated with the highest generalized-optical signal-to-noise ratio.

    Abstract: A network element is herein disclosed. The network element comprises an embedded device having one or more property affecting a function of the embedded device; a computing system having a processor and a memory, the memory being a non-transitory computer-readable medium storing a performance monitoring domain agent, a performance monitoring collector daemon, and a performance monitoring logger. The performance monitoring collector daemon is processor-executable code that when executed by the processor causes the processor to communicate with the embedded device and collect one or more performance information of the embedded device based on the one or more property. The performance monitoring domain agent is processor-executable code that when executed by the processor causes the processor to: retrieve the performance information from the performance monitoring collector daemon; format the performance information into a formatted data based on a metrics metadata file; and transmit the formatted data to the performance monitoring logger.

    Abstract: Disclosed herein are methods and systems for correcting power excursions. One exemplary network element may be provided with a processor; a first line port; a flexible ROADM module including a wavelength selective switch, a multiplexer, and one or more control block; a second line port; and a memory storing an orchestrator application and processor-executable instructions. Responsive to receiving a first signal indicative of an impending network state change, the processor-executable instructions cause the processor to pause all power adjustments by the control block on the flexible ROADM module and save at least one power set point value for each active passband from a first optical signal multiplexed into a second optical signal; and responsive to receiving a second signal indicative of the network state change, adjust an optical power of each active passband from the first optical signal multiplexed into the second optical signal using the power set point values.
