[0142] Figure 1 is an illustration of an example implementation of a fiber cleaning apparatus including a pneumatic circuit for monitoring air pressure and air flow as described herein.

[0143] Figure 2 yes Figure 1 An illustration of example components of one or more devices.

[0144] Figure 3 and Figure 4 is a flow chart of an example process associated with monitoring air pressure and air flow in a fiber cleaning apparatus. Detailed Description

[0146] The following detailed description of example implementations refers to the accompanying drawings.The same reference numbers in different drawings may identify the same or similar elements.

[0147] The fiber cleaning device may include a desktop assembly and a hand-held device (handset) connected to the desktop assembly (e.g., via an umbilical cord, etc.). The desktop assembly may include a solvent tank for containing a solvent for cleaning the end face of the optical fiber, 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 compressed air source provided by a user via a pressure supply port. The pneumatic circuit may include a vacuum generator that generates a vacuum at a vacuum port using an air flow from a compressed air source. The pneumatic circuit may also use a compressed air flow to provide a pressurized air flow at a pressure output port. The hand-held device may receive a vacuum from a vacuum port, a pressurized air flow from a pressure port, and a solvent from a solvent tank via an umbilical cord. The user may manipulate the hand-held device to clean the end face of the optical fiber using vacuum, pressurized air, and a solvent.

[0148] In addition to the pressure supply port, vacuum generator, vacuum port and pressure output port, the pneumatic circuit may include other circuit components (e.g., pressure regulator, air filter, valve, etc.). Over time, one or more air filters may become dirty, clogged, etc., and prevent the pneumatic circuit from providing pressurized air of sufficient pressure and / or volume flow to the pressure output port. Dirty and / or clogged filters may also prevent the vacuum generator from generating sufficient vacuum via the vacuum port. Additionally or alternatively, one or more circuit components (e.g., regulator, vacuum generator, or valve within the pneumatic assembly) may fail and prevent the device from operating normally. In addition, the compressed air source provided by the customer may not supply air of sufficient pressure and / or volume flow to the pressure supply port. When the air filter becomes dirty and / or clogged or a circuit component fails, the user must detect that the fiber cleaning device is not operating properly and try to troubleshoot the problem without knowing the cause of the problem, or send the device to a repair shop, which must then solve the problem without knowing the cause of the problem.

[0149] Some embodiments described herein provide a fiber cleaning device and / or a method performed by a fiber cleaning device, the method comprising receiving a pressure signal from a pressure sensor located in a pneumatic circuit. In some embodiments, the fiber cleaning device and / or method can use a sensor to detect a pressure difference across a circuit component, and can notify a user and / or take other actions (e.g., close a valve, adjust a pressure regulator, etc.). For example, the fiber cleaning device can detect whether an air filter is dirty and / or clogged, and can provide a message to the user indicating that the air filter is dirty and / or clogged, and which air filter in the system is dirty and / or clogged.

[0150] Additionally or alternatively, the fiber cleaning device and / or method may use a sensor to detect whether the customer-supplied compressed air supply is insufficient and notify the user and / or take other actions. In this way, the fiber cleaning device and / or method may detect a problem in the pneumatic circuit, control the pneumatic circuit to prevent further problems and / or damage to the pneumatic circuit, and / or provide a message to the user regarding the problem in the pneumatic circuit. In addition, the message may prevent the user from performing ineffective maintenance on the fiber cleaning device (e.g., replacing an air filter when the customer-supplied compressed air supply is insufficient and / or circuit components other than the air filter are not functioning properly).

[0151] Figure 1 is a diagram of an example embodiment 100 of a fiber cleaning device 102 including a pneumatic circuit 104 for monitoring air pressure and air flow as described herein. Figure 1As shown, the fiber cleaning device 102 may include a pneumatic circuit 104, a controller 106, a pressure supply port 108, a pressure output port 110, a pressure regulator 112, an input air filter 114, an output air filter 116, an output valve 118, a vacuum generator 120, a vacuum port 122, an exhaust port 124, a vacuum control valve 126, a supply pressure sensor 128, an input pressure sensor 130, an internal pressure sensor 132, an output pressure sensor 134 and a vacuum pressure sensor 136.

[0152] In some embodiments, and as Figure 1 As shown, the pneumatic circuit 104 may include a pressure supply port 108, a pressure output port 110, a pressure regulator 112, an input air filter 114, an output air filter 116, an output valve 118, a vacuum generator 120, a vacuum port 122, an exhaust port 124, a vacuum control valve 126, a supply pressure sensor 128, an input pressure sensor 130, an internal pressure sensor 132, an output pressure sensor 134, and a vacuum pressure sensor 136. The fiber cleaning device 102 and / or the pneumatic circuit 104 may receive a flow of gas from a compressed air source via the pressure supply port 108 and use the flow of gas to provide a pressurized gas flow at the pressure output port 110, provide a vacuum at the vacuum port 122 (e.g., via the vacuum generator 120), and output exhaust gas at the exhaust port 124 (e.g., from the vacuum generator 120).

[0153] In some embodiments, during the optical fiber end face cleaning process, the user can operate the fiber cleaning device 102 to clean the end face of the optical fiber using a pressurized gas flow from the pressure output port 110, a vacuum from the vacuum port 122, and / or a solvent from a solvent tank in the fiber cleaning device 102. For example, the fiber cleaning device 102 may include a handheld device connected to the pressure output port 110, the vacuum port 122, and / or the solvent tank via an umbilical cable, and the user can manipulate the handheld device (e.g., via a user input mechanism) to provide a pressurized gas flow, vacuum, and / or solvent to the end face of the optical fiber. In some embodiments, the controller 106 can control the handheld device and / or the pneumatic circuit 104 to provide pressurized air, vacuum, and / or solvent (e.g., in a pattern and / or a series of steps, etc.) based on user manipulation of the handheld device and / or instructions stored in the memory of the controller.

[0154] like Figure 1 As shown, the supply pressure sensor 128 can be located in the pneumatic circuit 104 between the pressure supply port 108 and the input air filter 114. In some embodiments, the supply pressure sensor 128 can sense the pressure provided by the compressed air source to the pressure supply port 108 and can generate a pressure supply signal based on the sensed pressure.

[0155] In some embodiments, and as Figure 1 As shown, the input air filter 114 may be located in the pneumatic circuit 104 between the supply pressure sensor 128 and the input pressure sensor 130. The input air filter 114 may filter air provided to the pneumatic circuit 104 by the compressed air source to remove contaminants (e.g., dust particles, moisture, etc.) that may damage and / or affect the performance of the pneumatic circuit 104 and / or the fiber cleaning device 102.

[0156] like Figure 1 As shown, the input pressure sensor 130 may be located in the pneumatic circuit 104 between the input air filter 114 and the pressure regulator 112. The supply pressure sensor 128 may sense the pressure input to the pressure regulator 112 and may generate an input pressure signal based on the sensed pressure.

[0157] In some embodiments, and as Figure 1 As shown, the pressure regulator 112 can be located between the input pressure sensor 130 and the internal pressure sensor 132 in the pneumatic circuit 104. The pressure regulator 112 can control the pressure of the air flow provided by the compressed air source to the pneumatic circuit 104 to provide system pressure to other circuit components (e.g., the output air filter 116, the output valve 118, the vacuum generator 120, the vacuum port 122, the vacuum control valve 126, etc.). For example, the pressure regulator 112 can reduce the pressure of the air flow provided by the compressed air source to prevent damage to other circuit components, and / or can increase the pressure of the air flow provided by the compressed air source to ensure that other circuit components, the pneumatic circuit 104 and / or the fiber cleaning device 102 operate normally. In some embodiments, the pressure regulator 112 can be adjustable so that the system pressure provided by the pressure regulator 112 can be adjustable.

[0158] like Figure 1 As shown, the internal pressure sensor 132 can be located in the pneumatic circuit 104 between the pressure regulator 112 and the output air filter 116 and between the pressure regulator 112 and the vacuum control valve 126. The internal pressure sensor 132 can sense the pressure provided by the pressure regulator 112 and can generate an internal pressure signal based on the sensed pressure.

[0159] In some embodiments, and as Figure 1As shown, the output air filter 116 can be located in the pneumatic circuit 104 between the internal pressure sensor 132 and the output pressure sensor 134. The output air filter 116 can filter the air provided by the pneumatic circuit 104 to the end face of the optical fiber to remove contaminants (e.g., dust particles, moisture, etc.) that may damage and / or increase signal loss of the optical fiber (which may negatively affect network performance).

[0160] like Figure 1 As shown, the output pressure sensor 134 may be located in the pneumatic circuit 104 between the output air filter 116 and the output valve 118. The output pressure sensor 134 may sense the pressure provided to the pressure output port 110 and may generate an output pressure signal based on the sensed pressure.

[0161] In some embodiments, and as Figure 1 As shown, the output valve 118 can be located between the output pressure sensor 134 and the pressure output port 110 in the pneumatic circuit 104. The output valve 118 can control the flow of pressurized air provided by the pressure output port 110. For example, the controller 106 can cause the output valve 118 to open and / or close (e.g., in a pattern and / or a series of steps, etc.).

[0162] like Figure 1 As shown, the vacuum control valve 126 can be located in the pneumatic circuit 104 between the internal pressure sensor 132 and the vacuum generator 120. In some embodiments, the vacuum control valve 126 can control the flow of pressurized air from the pressure regulator 112 to the vacuum generator 120. For example, the controller 106 can cause the vacuum control valve 126 to open and / or close (e.g., in a pattern and / or a series of steps, etc.).

[0163] In some embodiments, and as Figure 1 As shown, the vacuum generator 120 can be located between the vacuum control valve 126 and the vacuum pressure sensor 136 and between the vacuum control valve 126 and the exhaust port 124 in the pneumatic circuit 104. The vacuum generator 120 can use the pressurized gas flow from the pressure regulator 112 to generate a vacuum at the vacuum port 122 and output the exhaust through the exhaust port 124. In some embodiments, the fiber cleaning device 102 can use the vacuum generated by the vacuum generator 120 at the vacuum port 122 during the optical fiber end face cleaning process.

[0164] like Figure 1 As shown, vacuum pressure sensor 136 may be located between ejector 120 and vacuum port 122. Vacuum pressure sensor 136 may sense pressure (eg, negative pressure) provided by ejector 120 at vacuum port 122 and may generate a vacuum pressure signal based on the sensed pressure.

[0165] As used herein, the pressure supply signal from the supply pressure sensor 128, the input pressure signal from the input pressure sensor 130, the internal pressure signal from the internal pressure sensor 132, the output pressure signal from the output pressure sensor 134, and / or the vacuum pressure signal from the vacuum pressure sensor 136 may be collectively referred to as a pressure signal. Similarly, the supply pressure sensor 128, the input pressure sensor 130, the internal pressure sensor 132, the output pressure sensor 134, and / or the vacuum pressure sensor 136 may be collectively referred to as a pressure sensor.

[0166] As described herein, the controller 106 may be configured to receive one or more pressure signals from one or more pressure sensors and, based on the one or more pressure signals, determine whether the airflow meets a threshold, determine whether the pressure differential across a circuit component meets a threshold, and / or perform one or more actions, such as causing a message to be displayed to a user, causing one or more valves to be closed, causing one or more valves to be opened, causing the pressure regulator 112 to be adjusted, etc.

[0167] In some embodiments, the controller can receive the pressure signal, determine whether the airflow meets the threshold based on the pressure signal, and perform one or more actions based on the airflow not meeting the threshold. For example, the controller 106 can receive the pressure supply signal from the supply pressure sensor 128, and determine whether the input airflow provided to the pressure supply port 108 meets the threshold based on the pressure supply signal. The controller 106 can perform one or more actions based on the input airflow not meeting the threshold, such as causing a message (e.g., "Insufficient input airflow", "Check air supply connection", etc.) to be displayed to the user, causing the output valve 118 and / or the vacuum control valve 126 to be closed or opened, causing the pressure regulator 112 to be adjusted, etc.

[0168] As another example, the controller 106 may receive an output pressure signal from the output pressure sensor 134 and determine whether the output airflow meets a threshold based on the output pressure signal. The controller 106 may perform one or more actions based on the output airflow not meeting the threshold, such as causing a message (e.g., “Output airflow is insufficient,” “Check air filter,” etc.) to be displayed to a user, causing the output valve 118 and / or the vacuum control valve 126 to close or open, causing the pressure regulator 112 to be adjusted, etc.

[0169] In this way, the fiber cleaning device 102 using the controller 106 and the pressure sensor can monitor (e.g., in real time) the pressure level within the pneumatic circuit 104 and, when the pressure level does not meet a threshold, perform one or more actions to notify a user of the problem, provide information to the user to correct the problem, adjust the operation of the pneumatic circuit 104 (e.g., by opening and / or closing a valve, by adjusting a pressure regulator, etc.) to correct the problem to prevent damage to the fiber cleaning device 102 and / or prevent the fiber cleaning device 102 from damaging the end face of the optical fiber, etc.

[0170] In some embodiments, the controller may receive the first pressure signal and the second pressure signal, determine whether the pressure differential across the circuit component meets a threshold based on the first pressure signal and the second pressure signal, and perform one or more actions based on the pressure differential across the circuit component not meeting the threshold. For example, the controller 106 may receive a pressure supply signal from the supply pressure sensor 128 and an input pressure signal from the input pressure sensor 130, and determine whether the pressure differential across the input air filter 114 meets the threshold based on the pressure supply signal and the input pressure signal. The controller 106 may perform one or more actions based on the pressure differential across the input air filter 114 not meeting the threshold, such as causing a message (e.g., "Check input air filter", "Input air filter is dirty / blocked", "Replace input air filter", etc.) to be displayed to a user, causing the output valve 118 and / or the vacuum control valve 126 to close or open, causing the pressure regulator 112 to be adjusted, etc.

[0171] As another example, the controller 106 may receive an input pressure signal from the input pressure sensor 130 and an internal pressure signal from the internal pressure sensor 132, and determine whether a pressure differential across the pressure regulator 112 satisfies a threshold based on the input pressure signal and the internal pressure signal. The controller 106 may perform one or more actions based on the pressure differential across the pressure regulator 112 not satisfying the threshold, such as causing a message (e.g., “Pressure regulator failed,” “Check pressure regulator,” “Replace pressure regulator,” etc.) to be displayed to a user, causing the output valve 118 and / or the vacuum control valve 126 to close or open, causing the pressure regulator 112 to be adjusted, etc.

[0172] As another example, the controller 106 may cause the vacuum control valve 126 to open and receive the internal pressure signal from the internal pressure sensor 132 and the vacuum pressure signal from the vacuum pressure sensor 136. The controller 106 may determine whether the pressure differential across the ejector 120 meets a threshold based on the internal pressure signal and the vacuum pressure signal. The controller 106 may perform one or more actions based on the pressure differential across the ejector 120 not meeting the threshold, such as causing a message (e.g., “Ejector failed,” “Check ejector,” “Check vacuum control valve,” “Replace ejector,” “Replace vacuum control valve,” etc.) to be displayed to a user, causing the output valve 118 and / or the vacuum control valve 126 to close or open, causing the pressure regulator 112 to be adjusted, etc.

[0173] Thus, the fiber cleaning device 102 using the controller 106 and the pressure sensor can monitor (e.g., in real time) the pressure differential across the circuit components within the pneumatic circuit 104, and when the pressure differential does not meet a threshold, perform one or more actions to notify a user of the problem, provide information to the user to correct the problem, adjust the operation of the pneumatic circuit 104 (e.g., by opening and / or closing valves, by adjusting a pressure regulator, etc.) to correct the problem to prevent damage to the fiber cleaning device 102 and / or prevent the fiber cleaning device 102 from damaging the end face of the optical fiber, etc. For example, the fiber cleaning device 102 can identify the circuit components whose pressure differential across the circuit does not meet a threshold for the user, thereby preventing the user from performing ineffective and / or wasteful maintenance on the fiber cleaning device 102, such as replacing an air filter when a vacuum generator fails, etc.

[0174] In some embodiments, the fiber cleaning device 102 may include a filter cup for receiving water condensed in the input air filter 114 and / or the output air filter 116. For example, a compressed air source may provide an airflow that includes water (e.g., in the form of moisture, water vapor, etc.), and the input air filter 114 and / or the output air filter 116 may filter water from the airflow so that the water condenses and settles in the filter cup. In some embodiments, the filter cup may include a suction tube extending from the top of the filter cup into the filter cup (e.g., extending to half the depth of the filter cup, to three-quarters the depth of the filter cup, etc.), and water may be precipitated from the input air filter 114 and / or the output air filter 116 into the filter cup through the suction tube. By including the suction tube in the filter cup, the fiber cleaning device 102 may prevent water in the filter cup from flowing out of the filter cup and into the fiber cleaning device 102 when the unit is inverted (e.g., during shipping, transportation, etc.).

[0175] As indicated above, Figure 1 are provided only as examples. Other examples are contemplated and may differ from the Figure 1For example, some embodiments may include a physical differential sensor that senses a pressure differential across a circuit component (e.g., an air filter) and generates a pressure differential signal based on the pressure differential. In such an example, the controller 106 may be configured to receive the pressure differential signal and, based on the pressure differential signal, determine whether the airflow meets a threshold, determine whether the pressure differential across the circuit component meets a threshold, and / or perform one or more actions, such as causing a message to be displayed to a user, causing one or more valves to be closed, causing one or more valves to be opened, causing the pressure regulator 112 to be adjusted, etc.

[0176] As another example, some embodiments may include a controller 106 configured to receive one or more dynamic pressure signals from one or more pressure sensors when the fiber cleaning device 102 is performing a cleaning process, and to receive one or more static pressure signals from one or more pressure sensors when the fiber cleaning device 102 is not performing a cleaning process. The controller 106 may be configured to determine whether the airflow meets a threshold, determine whether the pressure difference between the dynamic pressure (e.g., based on the one or more dynamic pressure signals) and the static pressure (e.g., based on the one or more static pressure signals) meets a threshold, and / or perform one or more actions, such as causing a message to be displayed to a user, causing one or more valves to close, causing one or more valves to open, causing the pressure regulator 112 to be adjusted, etc. In some embodiments, the controller 106 may be configured to determine whether the pressure difference between the dynamic pressure and the static pressure meets the threshold by comparing the pressure difference to historical data (e.g., a historical baseline, a lookup table, etc.).
