[0117] The following detailed description of the exemplary embodiments is taken with reference to the accompanying drawings. The same reference numerals in different drawings may identify the same or similar elements.

[0118] Fiber cleaning equipment may include a benchtop assembly and a handheld device (e.g., connected to the benchtop assembly via an umbilical cord) connected to the benchtop assembly. The benchtop assembly may include a solvent tank for containing solvent for cleaning the end faces of optical fibers, a pneumatic circuit, a controller, a display, and one or more user input mechanisms (e.g., buttons, knobs, switches, etc.). The pneumatic circuit may be connected to a user-supplied compressed air source via a pressure supply port. The pneumatic circuit may include a vacuum generator that uses an airflow from the compressed air source to create a vacuum at a vacuum port. The pneumatic circuit may also use the compressed air flow to provide a pressurized airflow at a pressure output port. The handheld device may receive a vacuum from the vacuum port, a pressurized airflow from the pressure port, and solvent from the solvent tank via an umbilical cord. A user can manipulate the handheld device to clean the end faces of optical fibers using a vacuum, pressurized air, and solvent.

[0119] When the solvent in the device is low, the user can connect a hose to the inlet and outlet of the refill port assembly on the benchtop unit. The hose can be connected to a solvent bottle, and the bottle can be lifted to supply solvent to the solvent tank by gravity. However, gravity supply of solvent is slow and should be monitored to prevent overflow from the solvent tank, and there is a risk of contaminating the solvent tank.

[0120] Some embodiments described herein provide a method for filling and / or refilling a solvent tank and monitoring solvent in an apparatus for cleaning the end face of an optical fiber. In some embodiments, the method may include applying a vacuum to the solvent tank using the apparatus and receiving solvent from a solvent reservoir and in response to the applied vacuum using the solvent tank. For example, a hose may connect the vacuum port of the apparatus to the solvent tank, while another hose may connect the solvent reservoir to the solvent tank. In some embodiments, applying a vacuum to the solvent tank (e.g., via a hose and utilizing the vacuum port) generates suction to draw solvent from the solvent reservoir (e.g., via another hose) into the solvent tank.

[0121] In some embodiments, the method may include applying pressure to a solvent reservoir using the device and receiving solvent from the solvent reservoir and in response to the applied pressure into a solvent tank. For example, a first hose may connect the device's vent port to the solvent tank, a second hose may connect the solvent reservoir to the solvent tank, and a third hose may connect the device's pressure port to the solvent reservoir. In some embodiments, applying pressure to the solvent reservoir generates a positive pressure to push solvent from the solvent reservoir into the solvent tank.

[0122] In some embodiments, the method may include applying a vacuum to the solvent tank and applying pressure to the solvent reservoir. By applying a vacuum to the solvent tank and / or applying pressure to the solvent reservoir, the method and / or apparatus can fill the solvent tank in a shorter time than when using gravity supply. Additionally or alternatively, the method and / or apparatus can fill and / or refill the solvent tank from a solvent reservoir that is larger than that possible with a manual gravity supply process. For example, the solvent reservoir may be a gallon-sized container, a bucket (e.g., a 50-gallon bucket), etc., instead of a 225-milliliter container. Furthermore, filling and / or refilling the solvent tank from a larger solvent reservoir can save financial resources due to the relatively lower cost of a larger solvent reservoir compared to a smaller one.

[0123] Additionally or alternatively, the method may include monitoring the solvent level in the solvent tank during the filling process. For example, the method may include determining the solvent level in the solvent tank based on signals from sensors in the device, and performing one or more actions based on the solvent level, such as stopping the application of vacuum, displaying the solvent level, providing visual and / or audible alarms, etc. By monitoring the solvent level in the solvent tank during the filling process, the method and / or device can prevent overfilling. Additionally or alternatively, the method for filling and / or refilling the solvent tank may be an automated process rather than a manual one.

[0124] In some embodiments, the method may include filtering air entering the solvent reservoir in response to a vacuum applied to the solvent tank. Additionally or alternatively, the method may include connecting portions of a hose using fittings including valves to provide a closed loop for the solvent and / or airflow. By filtering air entering the solvent reservoir and / or providing a closed loop for the solvent and / or airflow, the method and / or apparatus can prevent contaminants from entering the solvent and / or the apparatus.

[0125] Figure 1 This is an illustration of an example embodiment 100 of a process (e.g., a method) of filling the solvent tank 118 of the fiber cleaning device 102 with solvent from the solvent reservoir 124 described herein. Figure 1As shown, the fiber cleaning device 102 may include a pneumatic circuit 104 (e.g., a pneumatic assembly), a vacuum generator 106, a pressure supply port 108, a pressure output port 110, a vacuum port 112, an exhaust port 114, a controller 116, a solvent tank 118, a float sensor 120, and a capacitive sensor 122. In some embodiments, the solvent reservoir 124 may be a container (e.g., a bottle, a barrel, etc.) for holding solvents (e.g., fiber cleaning solvents, engineering fluids (e.g., NOVEC 72DA engineering fluid from 3M), etc.) used by the fiber cleaning device 102.

[0126] In some implementations and such Figure 1 As shown, the pneumatic circuit 104 may include a vacuum generator 106, a pressure supply port 108, a pressure output port 110, a vacuum port 112, and an exhaust port 114. The fiber cleaning device 102 and / or the pneumatic circuit 104 may receive an airflow from a compressed air source via the pressure supply port 108 and use this airflow to provide a pressurized airflow at the pressure output port 110, provide a vacuum at the vacuum port 112 (e.g., via the vacuum generator 106), and output exhaust gas (e.g., from the vacuum generator 106) at the exhaust port 114. For example, the vacuum generator 106 may be a venturi vacuum. Additionally or alternatively, the fiber cleaning device 102 and / or the pneumatic circuit 104 may use a miniature compressor to provide a vacuum at the vacuum port 112 (e.g., when the fiber cleaning device 102 is portable, etc.).

[0127] In some embodiments, during the fiber end-face cleaning process, a user can operate the fiber cleaning device 102 to clean the fiber end face using a pressurized airflow from the pressure output port 110, a vacuum from the vacuum port 112, and / or a solvent from the solvent tank 118. For example, the fiber cleaning device 102 may include a handheld device connected via an umbilical cable to the pressure output port 110, the vacuum port 112, and / or the solvent tank 118, and the user can manipulate the handheld device to provide a pressurized airflow, a vacuum, and / or solvent to the fiber end face. In some embodiments, the controller 116 may control the handheld device and / or the pneumatic circuit 104 to provide pressurized air, a vacuum, and / or solvent (e.g., by mode and / or a series of steps, etc.) based on user manipulation of the handheld device and / or instructions stored in the controller's memory.

[0128] In some embodiments, during the filling process of solvent tank 118, vacuum generator 106 can apply a vacuum to solvent tank 118 through vacuum port 112 and first hose 126. For example, fiber cleaning device 102 can receive an airflow from a compressed air source through pressure supply port 108, and vacuum generator 106 can use this airflow to generate a vacuum at vacuum port 112. Figure 1 As shown, one end of the first hose 126 can be in fluid communication with the vacuum port 112 (e.g., connected to the vacuum port 112), while the other end of the first hose 126 can be in fluid communication with the solvent tank 118 (e.g., connected to the solvent tank 118). Similarly... Figure 1 As shown, the first hose 126 can be in fluid communication with the upper part of the solvent tank 118 in which there is no solvent, such that when a vacuum is applied through the first hose 126, air and / or gas are removed from the solvent tank 118.

[0129] In some embodiments, the vacuum port 112 may be in fluid communication with a handheld device. For example, the fiber cleaning device 102 may include a handheld device, and an umbilical cable may provide fluid communication between the vacuum port 112 and the handheld device. In some embodiments, during the solvent tank 118 filling process, a first hose 126 may be connected to the handheld device, and a vacuum generator 106 may apply a vacuum to the solvent tank 118 through the vacuum port 112, the handheld device, and the first hose 126.

[0130] like Figure 1 As shown, the second hose 128 can provide fluid communication between the solvent reservoir 124 and the solvent tank 118. For example, one end of the second hose 128 can be in fluid communication with the solvent tank 118 (e.g., connected to the solvent tank 118), and the other end of the second hose 128 can be in fluid communication with the solvent reservoir 124 (e.g., connected to the solvent reservoir 124). Figure 1 As shown, the second hose 128 can be in fluid communication with the lower part of the solvent reservoir 124 in which the solvent is contained, such that when a vacuum and / or suction is applied through the second hose 128, the solvent is removed from the solvent reservoir 124.

[0131] In some embodiments, a vacuum is applied to solvent tank 118 to extract air and / or gas from solvent tank 118. By extracting air and / or gas from solvent tank 118, the pressure inside solvent tank 118 can be reduced, thereby generating suction (e.g., through a second hose 128) to draw solvent from solvent reservoir 124 into solvent tank 118. In this way, fiber cleaning device 102 can use vacuum generator 106 to apply a vacuum to solvent tank 118 to draw solvent from solvent reservoir 124 into solvent tank 118. By applying a vacuum to solvent tank 118, fiber cleaning device 102 can fill solvent tank 118 in a shorter time than when using gravity supply. Additionally or alternatively, the method and / or device can fill and / or refill solvent tank 118 from a solvent reservoir larger than that possible with manual gravity supply. For example, solvent reservoir 124 can be a gallon-sized container, a bucket (e.g., a fifty-gallon bucket), etc., instead of a 225 ml container. Furthermore, due to the relatively lower cost of larger solvent reservoirs compared to smaller ones, filling and / or refilling solvent tank 118 from larger solvent reservoirs can save financial resources. Additionally or alternatively, methods and / or equipment for filling and / or refilling solvent tank 118 without a gravity supply can be considered adaptive tools for disabled persons, as per law and / or regulation.

[0132] In some embodiments, the fiber cleaning device 102 may include sensors to provide signals to the controller 116 regarding the contents of the solvent tank 118. In some embodiments, the sensors may sense the solvent level in the solvent tank 118 and generate signals based on the solvent level. For example, and as... Figure 1 As shown, the fiber cleaning device 102 may include a float sensor 120 and a capacitive sensor 122 in the solvent tank 118.

[0133] In some embodiments, the float sensor 120 can sense the liquid level in the solvent tank 118 and can generate a liquid level signal based on the liquid level. The float sensor 120 may include a float portion that floats in the liquid in the solvent tank 118 and thus rises and falls with the liquid level in the solvent tank 118. For example, when the liquid level in the solvent tank 118 is high, the float portion of the float sensor 120 may be in a high position. Figure 1 The position indicated by the solid line indicates that when the liquid level in solvent tank 118 is low, the float portion of float sensor 120 can be in a certain position. Figure 1 The position is indicated by the dashed line. Based on the position of the float portion, the float sensor 120 can generate a liquid level signal. For example, the float sensor 120 may include internal switches at different solvent levels, which can be triggered by the float portion, and the liquid level signal can be triggered by the float portion based on the internal switches.

[0134] In some embodiments, the capacitance sensor 122 can sense the capacitance of a fluid (e.g., liquid and / or gas) in the solvent tank 118 and can generate a capacitance signal based on the fluid's capacitance. In some embodiments, the fiber cleaning device 102 and / or controller 116 can be configured based on the known capacitance of air and solvent to determine the solvent level based on the capacitance signal. The capacitance sensor 122 can include two elements spaced apart from each other and can generate an electric field between the two elements. The capacitance sensor 122 can detect changes in the electric field caused by changes in the capacitance of the fluid between the two elements. The capacitance of the fluid changes when the amount and / or type of the fluid changes. In this way, the capacitance sensor 122 can detect changes in the amount and / or type of fluid in the solvent tank 118 and change the capacitance signal based on the detected changes. In some embodiments, the capacitance sensor 122 can be similar to the following reference. Figures 3A-3B A capacitive sensor described in further detail.

[0135] In some embodiments, the fiber cleaning device 102 may perform one or more actions based on a liquid level signal and / or a capacitance signal (e.g., using a controller 116, a pneumatic circuit 104, etc.). For example, the fiber cleaning device 102 may display (e.g., on a display of the fiber cleaning device 102) a solvent level based on a liquid level signal and / or a capacitance signal, provide visual alarms (e.g., lighting a light, panel, a series of lights, etc.), provide audible alarms (e.g., via a speaker, etc.), and so on. In some embodiments, one or more actions may provide information to the user confirming that the fiber cleaning device 102 is operating normally, notifying the user that the fiber cleaning device 102 is not operating normally, notifying the user that the solvent tank 118 needs to be refilled, notifying the user that the solvent tank 118 is contaminated, and so on.

[0136] In some embodiments, during the filling process of solvent tank 118, fiber cleaning device 102 may perform one or more actions to alter and / or stop the filling process based on a level signal and / or a capacitance signal. For example, fiber cleaning device 102 (e.g., using controller 116) may determine the solvent level in solvent tank 118 based on the level signal and / or capacitance signal, and may perform one or more actions based on the solvent level, such as: reducing the vacuum intensity applied to solvent tank 118, stopping the application of vacuum, displaying the solvent level, providing a visual alarm, providing an audible alarm, etc.

[0137] In some embodiments, the fiber cleaning device 102 may determine that the solvent level in the solvent tank 118 meets an upper limit threshold based on a level signal and / or a capacitance signal, and stop applying vacuum based on the solvent level in the solvent tank 118 meeting the upper limit threshold. For example, the upper limit threshold may correspond to a solvent level in and above the solvent tank 118 that maintains the air gap required for proper operation of the solvent tank 118 and / or the fiber cleaning device 102 (e.g., to allow the fiber cleaning device 102 to pressurize the solvent tank 118, etc.). By monitoring the solvent level in the solvent tank 118 during the filling process, the fiber cleaning device 102 can prevent overfilling.

[0138] In some embodiments, during the filling process of solvent tank 118, fiber cleaning device 102 may determine the rate of change of solvent level in solvent tank 118 based on a level signal and / or a capacitance signal, and perform one or more actions based on that rate of change. Additionally or alternatively, fiber cleaning device 102 may determine that the rate of change of solvent level in solvent tank 118 meets a threshold, and perform one or more actions based on that threshold. For example, fiber cleaning device 102 may determine that the rate of change of solvent level in solvent tank 118 is decreasing or zero, and may stop applying vacuum. In some embodiments, a decreasing or zero rate of change of solvent level may indicate that solvent reservoir 124 is empty, there is a problem with the first hose 126 and / or the second hose 128 (e.g., blockage, disconnection, etc.), a fault in pneumatic circuit 104 (e.g., disconnected air source, blocked air filter, etc.), and so on. By monitoring the rate of change of solvent level in solvent tank 118 during the filling process, fiber cleaning equipment 102 can prevent damage to solvent tank 124 (e.g., caused by continued application of vacuum), prevent damage to fiber cleaning equipment 102, and prevent wasted time by providing information to the user (e.g., solvent tank 124 is empty, fiber cleaning equipment 102 needs maintenance, etc.).

[0139] In some implementations, and such as Figure 1 As shown, a mechanical fitting with two valves 130 can connect to a portion of the first hose 126, and another mechanical fitting with two valves 132 can connect to a portion of the second hose 128. In some embodiments, the mechanical fitting may include a male connector with the first valve of valves 130, 132, and a female connector with the second valve of valves 130, 132. For example, the mechanical fitting may be a quick-connect fitting, a push-in fitting, etc. When the user connects a portion of the first hose 126 and / or a portion of the second hose 128, the two valves of the mechanical fitting can prevent air and / or other contaminants from entering the first hose 126 and / or the second hose 128.

[0140] Additional or alternative land, and as such Figure 1 As shown, pipe 134 and air filter 136 can be used to filter air entering solvent reservoir 124 during the filling process. For example, when a vacuum is applied to solvent tank 118 and solvent is drawn from solvent reservoir 124 into solvent tank 118, pipe 134 and air filter 136 can filter air entering solvent reservoir 124 (e.g., through vents in the cover of solvent reservoir 124, pressure relief valves, etc.). By filtering the air entering solvent reservoir 124, pipe 134 and air filter 136 can prevent contaminants from entering solvent and / or fiber cleaning equipment 102.

[0141] As described above, the capacitance sensor 122 can detect changes in the amount and / or type of fluid in the solvent tank 118 and change the capacitance signal based on the detected changes. In some embodiments, the controller 116 can determine the rate of change of capacitance of the fluid in the solvent tank 118 based on the capacitance signal. Additionally or alternatively, the controller 116 can perform one or more actions based on the capacitance signal and / or the rate of change of capacitance of the fluid in the solvent tank 118, such as stopping the vacuum, displaying information about the fluid in the solvent tank 118, providing a visual alarm, providing an audible alarm, etc.

[0142] For example, the fiber cleaning device 102 and / or controller 116 can be configured to determine whether the solvent tank 118 is contaminated (e.g., contaminated with water, isopropanol, other liquids, etc.) based on a capacitance signal and the known capacitance and / or dielectric constant of air, solvent, water, isopropanol, and / or other liquids. As another example, the fiber cleaning device 102 and / or controller 116 can be configured to determine whether the solvent tank 118 is contaminated based on a capacitance signal from a capacitance sensor 122, a level signal from a float sensor 120, and a known correspondence between the capacitance signal and the level signal when only solvent is present in the solvent tank 118. The fiber cleaning device 102 and / or controller 116 can also be configured to perform one or more actions based on the determination that the solvent tank 118 is contaminated, such as stopping the vacuum, displaying information indicating that the solvent tank 118 is contaminated, providing a visual alarm, providing an audible alarm, etc. By detecting (e.g., using capacitive sensor 122) changes in the amount and / or type of fluid in solvent tank 118, fiber cleaning equipment 102 can prevent contaminants from damaging the fiber cleaning equipment 102.

[0143] In some embodiments, the fiber cleaning device 102 may include a benchtop assembly, which includes a pneumatic circuit 104, a controller 116, a solvent tank 118, a display, and one or more user input mechanisms (e.g., buttons, knobs, switches, etc.). In some embodiments, the benchtop assembly may include attachment mechanisms (e.g., threaded bolt holes, etc.) such that the fiber cleaning device 102 can be mounted to a portable trolley (e.g., with wheels, etc.) on which a compressed air source is mounted. Additionally or alternatively, the fiber cleaning device 102 may include a battery (e.g., an internal battery, a rechargeable battery, etc.) such that when mounted to a portable core with a compressed air source, the fiber cleaning device 102 can operate without a benchtop air source and / or benchtop power supply.

[0144] In some embodiments, the fiber cleaning device 102 may include a base plate of a housing, with a solvent tank 118 located within the housing on the base plate. In some embodiments, the base plate may include a discharge system to discharge solvent escaping from the solvent tank 118 to the outside of the housing. For example, the discharge system may include a channel in the base plate surrounding the solvent tank 118 and one or more holes connected to the channel for discharging solvent from the channel to the outside of the housing. Additionally or alternatively, the fiber cleaning device 102 and / or the controller 116 may be configured to discharge the solvent tank 118 by applying pressure to it (e.g., by opening a solenoid, etc.), causing solvent to flow out of the solvent tank 118 and be discharged through the discharge system.

[0145] In some embodiments, the fiber cleaning device 102 may include a solvent delivery system that supplies solvent from a solvent tank 118 to a handheld device via an umbilical cable for cleaning the end face of the optical fiber. During the cleaning operation, the fiber cleaning device 102 may be configured to provide multiple solvent injections from the solvent tank 118 to the handheld device using the solvent delivery system, wherein each injection includes a known volume of solvent. The fiber cleaning device 102 may be configured to determine, based on a capacitance signal from a capacitance sensor 122, the expected decrease in the solvent level in the solvent tank 118 at each injection. The fiber cleaning device 102 may also be configured to determine, based on capacitance signals before and after the injection, whether a measured decrease in the solvent level for that injection corresponds to the expected decrease. In some embodiments, the fiber cleaning device 102 may be configured to perform one or more actions, such as stopping the cleaning operation, displaying information to the user, providing visual and / or audible alarms, etc., if the measured decrease in the solvent level for that injection does not correspond to the expected decrease. In this way, the fiber cleaning device 102 can be configured to detect faults in the solvent delivery system (e.g., blocked ports, solenoid failures, pipe kinks, etc.) based on the capacitance signal from the capacitance sensor 122.

[0146] In some embodiments, the fiber cleaning device 102 may be configured to allow a user to select a standard cleaning profile, a customized cleaning profile, etc., wherein the cleaning profile configures the fiber cleaning device 102 to perform a series of cleaning steps (e.g., providing pressurized air, providing solvent, applying vacuum, etc.) and parameters for the cleaning steps (e.g., pressure and / or duration for providing pressurized air, amount and / or duration for providing solvent, pressure and / or duration for applying vacuum, etc.). Additionally or alternatively, the fiber cleaning device 102 may be configured to allow a user to create and / or edit cleaning profiles (e.g., by manipulating an input mechanism on the fiber cleaning device 102, by loading a cleaning profile created and / or edited on another device onto the fiber cleaning device 102, etc.). In this way, the fiber cleaning device 102 can allow a user to customize the cleaning profile, cleaning steps, and / or parameters for the cleaning steps based on the intended application (e.g., monofiber, multifiber propulsion (MPO), etc.).

[0147] As indicated above, Figure 1 This is provided as an example only. Other examples are expected and may differ from the reference. Figure 1 Example of the description.

[0148] Figure 2 This is an illustration of an exemplary embodiment 200 of a process (e.g., a method) of filling the solvent tank 218 of the fiber cleaning device 202 with solvent from the solvent reservoir 224 described herein. Figure 2 As shown, the fiber cleaning device 202 may include a pneumatic circuit 204, a vacuum generator 206, a pressure supply port 208, a pressure output port 210, a vacuum port 212, an exhaust port 214, a controller 216, a solvent tank 218, a float sensor 220, and a capacitive sensor 222.

[0149] In some embodiments, the fiber cleaning device 202 and the solvent reservoir 224 may be similar to those described herein. Figure 1 The fiber cleaning device 102 and solvent reservoir 124 are described. Additionally or alternatively, the first hose 226, the second hose 228, valve 230, and valve 232 may be similar to those described herein. Figure 1 The first hose 126, the second hose 128, the valve 130, and the valve 132 are described.

[0150] like Figure 2As shown, the third hose 234 can provide fluid communication between the pressure output port 210 and the solvent reservoir 224. For example, one end of the third hose 234 can be in fluid communication with the pressure output port 210 (e.g., connected to the pressure output port 210), and the other end of the third hose 234 can be in fluid communication with the solvent reservoir 224 (e.g., connected to the solvent reservoir 224). In some embodiments, and as shown... Figure 2 As shown, the third hose 234 can be in fluid communication with the upper part of the solvent reservoir 224, where there is no solvent.

[0151] In some embodiments, during the filling process of solvent tank 218, pneumatic circuit 204 can apply pressure to solvent reservoir 224 through pressure output port 210 and third hose 234. For example, fiber cleaning device 202 can receive airflow from compressed air source through pressure supply port 208, and pneumatic circuit 204 can use this airflow to generate pressurized airflow at pressure output port 210.

[0152] In some embodiments, the pressure output port 210 may be in fluid communication with a handheld device. For example, the fiber cleaning device 202 may include a handheld device, and an umbilical cable may provide fluid communication between the pressure output port 210 and the handheld device. In some embodiments, during the solvent tank 218 filling process, a third hose 234 may be connected to the handheld device, and the pneumatic circuit 204 may apply pressure to the solvent reservoir 224 through the pressure output port 210, the handheld device, and the third hose 234.

[0153] In some embodiments, applying pressure to solvent reservoir 224 can increase the pressure within solvent reservoir 224 and push solvent out of solvent reservoir 224 through second hose 228 and into solvent tank 218. In this way, fiber cleaning device 202 can apply pressure to solvent reservoir 224 using pressure output port 210 to push solvent from solvent reservoir 224 to solvent tank 218. By applying pressure to solvent reservoir 224, fiber cleaning device 202 can fill solvent tank 218 in a shorter time than when using gravity supply. Additionally or alternatively, by applying pressure to solvent reservoir 224 via third hose 234 and using first hose 226 and second hose 228, fiber cleaning device 202 can use a closed loop for fluid flow to fill solvent tank 218, which can reduce the risk of contamination (e.g., contamination by air, open atmosphere, etc.) of fiber cleaning device 102, solvent reservoir 224, etc.

[0154] In some embodiments, during the filling process of solvent tank 218, a pressure relief valve (e.g., on solvent reservoir 224) can be used to prevent the applied pressure from exceeding a threshold at which solvent reservoir 224 may fail (e.g., break, crack, etc.). For example, a top component may be placed on solvent reservoir 224, and the top component may include a pressure relief valve (e.g., a safety ejection mechanism, etc.).

[0155] In some embodiments, pushing solvent into solvent tank 218 may push air and / or gas through first hose 226 to vacuum port 212. In some embodiments, pneumatic circuit 204 and / or vacuum generator 206 may be configured to release air and / or gas entering vacuum port 212 from first hose 226 through exhaust port 214. Additionally or alternatively, fiber cleaning device 202 may be configured to apply a vacuum (e.g., via first hose 226) to solvent tank 218 at vacuum port 212 while pressure is applied to solvent reservoir 224 at pressure output port 210 (e.g., in a manner similar to that described herein). Figure 1 (the method described).

[0156] In some embodiments, the fiber cleaning device 202 may be based on a liquid level signal from the float sensor 220, a capacitance signal from the capacitance sensor 222, the rate of change of the liquid level signal, and / or the rate of change of the capacitance signal, in a manner similar to that described herein. Figure 1 The aforementioned actions are performed (e.g., using controller 216, pneumatic circuit 204, etc.) to perform one or more actions. In some embodiments, instead of reducing the applied vacuum intensity or stopping the application of vacuum, or otherwise, the fiber cleaning device 202 may reduce the pressure applied to the solvent reservoir 224, stop applying pressure, etc.

[0157] As indicated above, Figure 2 This is provided as an example only. Other examples are expected and may differ from the reference. Figure 2 Example of the description.

[0158] Figures 3A-3B This is an illustration of an example embodiment of the capacitive sensor 300 described herein. In some embodiments, Figure 1 Capacitive sensor 122 and / or Figure 2 The capacitive sensor 222 can be similar to the capacitive sensor 300.

[0159] For reference Figure 1 As described in capacitive sensor 122, the capacitive sensor may include two elements spaced apart from each other, which can generate an electric field between the two elements and can detect changes in the electric field caused by changes in the capacitance of the fluid between the two elements. Figures 3A-3BAs shown, the two elements of the capacitive sensor 300 can be a tube 302 with sidewalls 304 and a rod 306 located within the tube 302. In some embodiments, the tube 302 and the rod 306 can extend vertically within a solvent tank (e.g., solvent tank 118, solvent tank 218, etc.).

[0160] In some embodiments, the capacitance sensor 300 can generate an electric field between the tube 302 and the rod 306, and can generate a capacitance signal based on the capacitance of the fluid (e.g., liquid, gas, etc.) in the electric field between the tube 302 and the rod 306. For example, when the capacitance sensor 300 is in a solvent tank containing solvent and air, the lower part of the tube 302 will be filled with solvent, and the upper part of the tube 302 will be filled with air. The capacitance sensor 300 can generate a capacitance signal based on the combined capacitance of the solvent and air within the tube 302 (e.g., between the sidewall 304 and the rod 306). As the solvent level in the solvent tank increases or decreases, the combined capacitance may change, which leads to a change in the capacitance signal generated by the capacitance sensor 300.

[0161] As referenced in this article Figure 1 The solvent tank of the fiber cleaning equipment may be contaminated with water, isopropanol, and / or other liquids. In some embodiments, a capacitance sensor 300 can be used to detect contamination when water, isopropanol, and / or other liquids enter the solvent tank. For example, when water enters the solvent tank and then into pipe 302, the water may change the combined capacitance, which causes a change in the capacitance signal generated by the capacitance sensor 300. The fiber cleaning equipment and / or controller (e.g., controller 116, controller 216, etc.) may be configured to determine whether the solvent tank is contaminated based on changes in the capacitance signal and the known capacitances of air, solvent, water, and / or other liquids.

[0162] However, in some embodiments, when water enters the solvent tank, because the solvent has a higher density than water, the water may float on top of the solvent and may not enter pipe 302. Therefore, in some embodiments, and as... Figure 3B As shown, the capacitance sensor 300 may include a tube 302 having vertically spaced openings 308 (e.g., vertically spaced openings) in a sidewall 304, such that water floating on top of the solvent can enter the tube 302 through the openings 308 (e.g., grooves, holes, windows, etc.), changing the combined capacitance and altering the capacitance signal generated by the capacitance sensor 300.

[0163] In some embodiments, the vertical spacing of the openings 308 can ensure that when a contaminating fluid (e.g., water, isopropanol, and / or other liquids) is in a solvent tank, the contaminating fluid can enter the tube 302 and be detected, regardless of the solvent level at the time of contamination. For example, the openings 308 can be located in the sidewall 304, allowing the contaminating fluid to enter the tube 302 at any vertical height along the tube 302.

[0164] Despite Figure 3B The example embodiment shows an opening 308 with a rectangular shape, but some embodiments may include an opening 308 with other shapes (e.g., circular, triangular, etc.). Additionally or alternatively, although in Figure 3B Each opening 308 shown in the example implementation has the same shape and / or size, but some implementations may include openings 308 having different shapes and / or sizes from one another.

[0165] In some embodiments, the capacitive sensor 300 may include a conduit with a bottom O-ring seal mechanism, wherein the conduit protects the capacitive sensor 300 from short-circuiting when contaminating fluids (e.g., water, isopropanol, and / or other liquids) enter the solvent tank. In some embodiments, the conduit may be a Teflon conduit, and the O-ring may be formed of a material that expands when exposed to the solvent used in the solvent tank, thereby forming a tighter seal. For example, the conduit may be polytetrafluoroethylene (PTFE), and the O-ring may be a VITON O-ring.

[0166] As indicated above, Figures 3A-3B This is provided as an example only. Other examples are expected and may differ from the reference. Figures 3A-3B Example of the description.

For example, communication interface 470 may include an Ethernet interface, an optical interface, a coaxial interface, an infrared interface, a radio frequency (RF) interface, a universal serial bus (USB) interface, a Wi-Fi interface, a cellular network interface, etc.

[0172] Device 400 can perform one or more of the processes described herein. Device 400 may execute these processes based on software instructions stored in non-transitory computer-readable media such as memory 430 and / or storage unit 440, executed by processor 420.

[0175] Figure 5 This is a flowchart of an example process 500 related to filling the solvent tank of a fiber cleaning device with solvent from a solvent reservoir. In some embodiments, Figure 5 One or more process blocks can be performed by devices used for cleaning the end faces of optical fibers (e.g., fiber cleaning device 102, fiber cleaning device 202, device 400, etc.).

Figure 5 Compared to the blocks depicted in the diagram, process 500 may include additional blocks, fewer blocks, different blocks, or blocks arranged differently. Alternatively, two or more blocks in process 500 may be executed in parallel.

[0186] Figure 6 This is a flowchart of an example process 600 related to filling the solvent tank of a fiber cleaning device with solvent from a solvent reservoir. In some embodiments, Figure 6 One or more process blocks can be performed by devices used for cleaning the end faces of optical fibers (e.g., fiber cleaning device 102, fiber cleaning device 202, device 400, etc.).

[0187] like Figure 6As shown, process 600 may include applying pressure to a solvent reservoir (block 610). For example, a device for cleaning the end face of an optical fiber (e.g., using pressure output ports 110 or 210, processor 420, memory 430, storage unit 440, input unit 450, output unit 460, communication interface 470, etc.) may apply pressure to the solvent reservoir as described above.
