    摘要： A device may determine a time-of-flight measurement by performing a sample of a sensor based on light received via at least one first spectral filter, wherein the at least one first spectral filter is associated with a spectral range for a time-of-flight measurement; determine that a condition is satisfied with regard to the time-of-flight measurement, wherein the condition relates to an orientation or a position of the sensor or the sensor device relative to a measurement target; trigger a spectrometry measurement to be performed based on determining that the condition is satisfied with regard to the time-of-flight measurement; and perform, based on light received via at least one second spectral filter and by performing a sample of the sensor, the spectrometry measurement for the measurement target based on the condition being satisfied with regard to the time-of-flight measurement.

    摘要： Mapping of ports to other network components is generated by physically bending a fiber optic cable and then determining which optical network terminals experience a signal power loss (or receive attenuated signals) based on the bending. The physical bending can be done using a bending tool and the optical network terminals that experience the signal power loss can be identified using a back-end database operation. Generally, the correspondence between the physical bending and the power loss at the downstream components and or upstream components of the network is used to create the mapping of the ports at the splitter level.

    摘要： An optical cable structure is discussed that enables a distributed optical fiber sensor to detect acoustic vibration and other measurands, which could be, for example, changes in temperature, changes in static pressure, and changes in static strain. The optical cable structure includes first and second optical fibers disposed within a thin walled, elliptical, gel filled, loose tube helically wound within a cable wall of the optical cable structure. The optical cable structure further includes an additional optical fiber bonded to a strength member using a tight encapsulant. Because the additional optical fiber is fixed to the strength member and disposed with its axis parallel to the strength member, the additional optical fiber experiences the full axial strain on the optical cable structure, unlike the first and second optical fibers contained within the helically wound loose tube, thereby providing a contrast to the strain response coefficients of the first and second optical fibers.

    摘要： An example mount may include a strap (or any other type of clamping mechanism) engaging with an external surface of an antenna. The strap may be connected to a strap base with a canted wall also engaging with the external surface of the antenna. The engagement of the canted wall may be through an abutment of the canted wall against the corresponding external surface of the antenna at a single point or along a single line. Because the entirety of the canted wall does not have to be flush with the corresponding external surface of the antenna, the mount can couple to any kind of antenna form factor, such as curved antennas and antennas with imperfections and protrusions.

    摘要： In some examples, a temperature distribution sensor may include a laser source to emit a laser beam that is tunable to a first wavelength and a second wavelength for injection into a device under test (DUT). A first wavelength optical receiver may convert a return signal corresponding to the first wavelength with respect to Rayleigh backscatter or Raman backscatter Anti-Stokes. A second wavelength optical receiver may convert the return signal corresponding to the second wavelength with respect to Rayleigh backscatter or Raman backscatter Stokes. Bending loss associated with the DUT may be determined by utilizing the Rayleigh backscatter signal corresponding to the first wavelength and the Rayleigh backscatter signal corresponding to the second wavelength. Further, temperature distribution associated with the DUT may be determined by utilizing the Raman backscatter Anti-Stokes signal corresponding to the first wavelength and the Raman backscatter Stokes signal corresponding to the second wavelength.
