Detailed Description
The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.
As shown in fig. 1, 2, 3, 4, and 5, a method of fiber-optic endface cleaning comprising the steps of:
s1: starting the cleaning tool to enable the cleaning tool to extract air, and purifying and drying the air in the cleaning tool to remove impurities and moisture in the air so as to enable the cleaning tool to obtain clean and dry purified air;
s2: the cleaning tool is aligned with the end face of the optical fiber 300, the cleaning tool pressurizes the purge gas, the pressurized purge gas is sprayed onto the end face of the optical fiber 300, and the end face of the optical fiber 300 is purged by the high-pressure purge gas, thereby blowing off the foreign substances on the end face of the optical fiber 300.
It should be noted that the cleaning tool is actually a tool capable of sucking air, drying, filtering, and spraying air under pressure, and during actual cleaning, the cleaning tool can be cleaned in a clean and dustless environment to avoid pollution during cleaning.
Because the cleaning tool can spray clean and dry clean gas (air) on the end face of the optical fiber 300, the clean gas can blow away dust or sundries on the end face of the optical fiber 300, because the cleaning tool cleans the optical fiber 300 in a non-physical contact mode, paper scraps cannot be left, and the air is dried and filtered, water stains and new pollutants cannot be left on the end face of the optical fiber 300, the end face of the optical fiber 300 cannot be scratched due to friction, and the sundries can be thoroughly blown away from the end face of the optical fiber 300 by high-pressure airflow, so the cleaning effect is very good.
It should be noted that, unlike dust suction, the method performs cleaning by using the principle of gas purging (dust blowing), which may cause the defect of incomplete removal of the contaminants if the dust suction is used to suck the contaminants on the end surface of the optical fiber 300, and may also scratch the end surface of the optical fiber 300, so that the effect of non-physical contact cleaning cannot be achieved.
As shown in fig. 1, 3, 4, and 5, on the basis of the above embodiment, in step S2, the gas outlet 210 of the cleaning tool is aligned vertically with the end face of the optical fiber 300, and a gap 400 remains between the gas outlet 210 and the end face of the optical fiber 300, and purge gas is blown onto the end face of the optical fiber 300 from the vertical direction and then blown out from the gap 400.
During actual cleaning, the gas blown out by the cleaning tool vertically acts on the end face of the optical fiber 300, and a small gap 400 is reserved between the gas outlet 210 of the cleaning tool and the end face of the optical fiber 300, so that the cleaning gas can be conveniently blown out from the gap 400 with the contaminants on the end face of the optical fiber 300, the cleaning tool is ensured not to touch the end face of the optical fiber 300, and the end face of the optical fiber 300 is prevented from being damaged.
As shown in fig. 1 and 3, step S2 is repeated at least twice so that the end face of the optical fiber 300 is subjected to the purging twice or more, thereby ensuring the cleaning effect. Preferably, to enhance the cleaning effect, the end face of the optical fiber 300 may be cleaned repeatedly a plurality of times, i.e., dust is blown onto the end face of the optical fiber 300 twice or more.
As shown in fig. 1 and 3, the method further includes step S3: the cleaned end face of the optical fiber 300 is sheathed with a protective jacket to prevent recontamination. The protective sheath can insulate the end face of the optical fiber 300 from the external space, and prevent contaminants (dust or water) from re-adhering to the end face of the optical fiber 300.
As shown in fig. 1, 3, 4, and 5, in step S1, the optical fibers 300 are connected to an MPO connector, an MPO adapter is inserted onto the MPO connector, and a cleaning tool is inserted into the MPO adapter so as to align the end faces of the optical fibers 300 on the MPO connector.
Preferably, the optical fibers 300 are arranged as optical fibers 300 on an MPO connector to which an MPO adapter is attached, and the nozzle 200 of the cleaning tool is inserted into the MPO adapter right before aligning the end faces of the optical fibers 300 during cleaning.
The cleaning method is particularly suitable for MPO male heads, and because the end face of the finished MPO male head has two guide pins with higher needles, the end face of the optical fiber 300 in the middle of a small space is difficult to wipe, so the dust blowing method can clean the end face of the optical fiber 300 without contacting the optical fiber 300, and the problem that the end face of the optical fiber 300 in a narrow space is difficult to clean is solved.
Provision is made before cleaning, when the optical fibers are arranged on separate MPO connectors, either by adding an MPO adapter to align the nozzles of the cleaning tool with the MPO connector end faces or by replacing the nozzles of the cleaning tool directly with the MPO connector end faces.
As shown in fig. 1, 3, 4, and 5, the cleaning tool is provided with a square type nozzle 200 when the optical fiber 300 is positioned on the MPO connector, and is provided with a circular type nozzle 200 when the optical fiber 300 is positioned on the LC connector or the SC connector.
Preferably, the cleaning tool can be equipped with different types of nozzles 200 for the optical fibers 300 on different connectors, and during actual cleaning, a square type nozzle 200 can be used if the optical fibers 300 on the MPO connector are cleaned, and a circular type nozzle 200 can be used if the optical fibers 300 on the LC connector or the SC connector are cleaned, so that the shape of the nozzle 200 is adapted to the shape of the connector.

As shown in fig. 2, a movable piston 180 is disposed within the pressurizing chamber 140, and pushing the piston 180 draws air into the intake port 110 or discharges air from the nozzle 200.
Pushing and pulling the piston 180 can make the pressurizing cavity 140 suck gas and pressurize; in practical configurations, when the first switch 160 is turned on and the second switch 170 is turned off, the piston 180 may be pulled leftward to create a negative pressure in the pressurized chamber 140, and then the gas may be sucked into the pressurized chamber 140, and after the gas is sucked, the first switch 160 is turned off and the second switch 170 is turned on, and then the piston 180 is pushed rightward to blow the gas in the pressurized chamber 140 out of the nozzle 200; the structure is very ingenious, the purposes of air suction and dust blowing can be achieved only through the first switch 160, the second switch 170 and the piston 180, and the structure is very convenient and reliable.
