  • Patent number: 11212001
    Abstract: Aspects include obtaining, by a sending system, a measured receive optical power level of an optical signal that was received at a receiving system coupled to the sending system via an optical network. The optical signal was sent via an optical transmitter of the sending system to an optical receiver of the receiving system. An optimal receive optical power level of the optical receiver of the receiving system is determined by the sending system. The sending system adjusts an output optical power level of the optical transmitter in response to determining that the measured receive optical power level is not within a threshold of the optimal receive optical power level. The adjusting is performed without decoupling the sending system from the receiving system.

  • Patent number: 11187858
    Abstract: A fiber-optic switching system is provided which includes an optical fiber switch having first and second optical fiber portions and an electrically-controlled actuator. The first and second optical fiber portions are spaced apart with a gap between the portions that is sized to allow for light signal coupling between the optical fiber portions in a signal-passing state of the switch. The electrically-controlled actuator is coupled to transition the switch between the signal-passing state, where the light signal is allowed to pass between the optical fiber portions, and a signal-non-passing state, where the light signal is prevented from passing between the optical fiber portions. The electrically-controlled actuator includes an electroactive material exhibiting a physical change with change in an applied electrical field, where the physical change facilitates transitioning the optical fiber switch between the signal-passing and the signal-non-passing states.

  • Patent number: 10972182
    Abstract: A method of using an adjustable attenuation fiber optic wrap plug (“AAFOWP”) includes receiving initial data into a wireless module of the AAFOWP, wherein the initial data corresponds to an initial desired attenuation level that the first AAFOWP is to achieve. The method also includes moving, in response to receiving the initial data, an arm by an actuator to change a bend radius of an optical fiber wrap in the AAFOWP, thus adjusting an attenuation through the AAFOWP to the initial desired attenuation level.
