  • Publication number: 20240259096
    Abstract: Systems and methods for optimization of spectrum sharing in optical line systems include, for at least one fiber having optical spectrum being shared by at least two users in an optical line system, assigning value to the optical spectrum; determining using a policy and the assigned value of the optical spectrum how to partition the optical spectrum between the at least two users; and causing implementation of the partition of the optical spectrum. The assigned value of the optical spectrum can be based on information carrying capacity in bandwidth per second. The assigned value of the optical spectrum accounts for performance versus frequency, such that, e.g., two or more of the at least two users have different amounts of the optical spectrum from one another.

  • Publication number: 20230415396
    Abstract: A method of continuously manufacturing a cured membrane includes continuously compounding and mixing a vulcanizable rubber composition in a mixing extruder while continuously removing gasses from the vulcanizable rubber composition during mixing with a vacuum. The vulcanizable rubber composition may be continuously extruded to form an extrudate, which may be continuously calendered to form a green membrane. The green membrane may be continuously cured, such as by a hot air conveyor curing system, to form a cured membrane.

  • Publication number: 20230318712
    Abstract: A coherent optical transmitter includes circuitry connected to a coherent modulator; and a plurality of tunable optical filters (TOFs) connected to one another and connected to an output of the coherent modulator, wherein the plurality of tunable optical filters are configurable to create an effective transfer function having a variable width. The TOFs are cascaded and can be included in discrete form on electro-optic printed circuit boards (PCBs), or integrated in various electro-optic material systems such as in silicon photonics, photonic integrated circuits (PICs), as well as hybrid and other approaches. The advantage of this approach includes improved OSNR in colorless transmitters.

  • Patent number: 11575556
    Abstract: A communication system is configured to generate a perturbed signal by perturbing an amplitude of a spectrum of an original signal in one or more spectral regions, and to propagate the perturbed signal through components of the communication system. The communication system is further configured to obtain a measurement of the perturbed signal in a first spectral region of the one or more spectral regions following the propagation of the perturbed signal, and to calculate an estimate of an impairment associated with the communication system based on the measurement.

  • Publication number: 20220321247
    Abstract: A system is configured to measure (602) a forward error correction (FEC) decoding property (216) associated with applying FEC decoding (214) to FEC-encoded bits or symbols at a receiver device (202) deployed in a communication network (100). The system is configured to provide (606) an assessment of operating conditions of the receiver device based on the FEC decoding property. The FEC decoding property comprises, for example, a distribution of a number of iterations of a FEC decoding operation applied to a plurality of FEC blocks processed within a period of time. In some examples, the FEC decoding property comprises any one of heat, temperature, current, voltage, active clock cycles, idle clock cycles, activity of parallel engines, activity of pipeline stages, and input or output buffer fill level of the FEC decoding. The assessment is based, for example, on a comparison between the FEC decoding property and reference FEC data (218).

  • Publication number: 20220034550
    Abstract: A heated flue includes a flue section configured to be fluidly coupled to an exhaust outlet of a boiler. At least one heater is mechanically coupled to the flue section to heat an exhaust gas flowing within. A sensor is mechanically coupled to the flue section or disposed within the flue section. The sensor is configured to measure a parameter of the exhaust gas flowing within. A controller is operatively coupled to the at least one heater and the sensor. The controller is configured to control a temperature of the exhaust gas based on the parameter. A method to vent a condensing boiler into a non-condensing rated stack is also described.
