Description

Technical Field

[0001] The invention relates to the technical field of optical performance detection of a plug-in optical splitter, and in particular to an optical performance detection device and a detection method for a plug-in optical splitter. Background Art

[0002] The plug-in optical splitter is an integrated waveguide optical power distribution device based on a quartz substrate. It has the characteristics of small size, wide operating wavelength range, high reliability, good splitting uniformity, etc. It is particularly suitable for connecting the central office and terminal equipment in a passive optical network and realizing the splitting of optical signals. When performing optical performance testing on the plug-in optical splitter, most of them use manual testing, which is inefficient. Therefore, the optical performance testing of the plug-in optical splitter is mostly carried out using a detection device. According to the detection device of the prior art, it can be known that during detection, the input end is plugged into the connection end of the stable light source by using the driving device, and then the connectors on the optical power meter are inserted into the output end of the optical performance detection device of the plug-in optical splitter in sequence, so that the optical performance detection device of the plug-in optical splitter can be tested. However, when plugging in, it is easy to cause the plug-in optical splitter to be squeezed to a large extent due to excessive plugging, thereby causing damage to the input end and the output end. Moreover, because the plug-in optical splitter is provided with multiple output ends and one input end, when an unqualified output end appears during detection, the corresponding output end cannot be marked, which is inconvenient for later detection and maintenance of the unqualified output end. Therefore, we propose an optical performance detection device and detection method for a plug-in optical splitter. Summary of the invention

11. A detection method for an optical performance detection device of a plug-in optical splitter according to any one of claims 1 to 10, characterized in that: The method comprises the following steps: Step 1: First, multiple groups of standard output fibers (9) are connected to the optical power device (5) respectively, and the standard input fibers (8) are connected to the stable light source (2), and the plug-in optical splitter (11) is placed on the base (1). With the cooperation of the positioning plate (15), the plug-in optical splitter (11) can be positioned, and then the hydraulic cylinder (140) drives the clamping plate (142) to move, and the clamping plate (142) can clamp and fix the front and rear side walls of the plug-in optical splitter (11); Step 2: The controller (6) controls the motor (45) to work, the motor (45) drives the rotating rod (43) to rotate, the rotating rod (43) drives the first gear (44) to rotate, the first gear (44) moves on the outer wall of the first rack (40), so that the sliding frame (42) drives the connecting rod (41) to move, the connecting rod (41) drives the moving plate (10) to move, the moving plate (10) drives the multiple groups of standard output fibers (9) and standard input fibers (8) to move and insert them into the input end (12) and the output end (13), and at the same time the moving plate (10) drives the slider (18) to move in the slide groove (17), and the slider (18) moves to the receiving The force plate (166) is pressed, the force plate (166) drives the moving rod (165) and the pressing plate (162) to move, the pressing plate (162) stretches the spring (163), the pressing plate (162) drives the pressure rod (161) to press the pressure sensor (160), the pressure sensor (160) transmits a signal to the controller (6), and the controller (6) controls the motor (45) to stop working immediately. At this time, the multiple groups of standard output fibers (9) and the standard input fibers (8) are just inserted into the input end (12) and the output end (13), and the problem of excessive pressing will not occur, thereby ensuring that the input end (12) and the output end (13) are not damaged; Step 3: After the plurality of groups of standard output fibers (9) and the standard input fibers (8) are respectively inserted into the input end (12) and the plurality of groups of output ends (13), the controller (can determine whether each channel of the plug-in optical splitter (11) is qualified. If qualified, the staff removes the plug-in optical splitter (11). When unqualified is detected, the marking component (7) can mark the output end (13) of the unqualified channel, the first electric telescopic rod (73) drives the connecting plate (72) to move, the connecting plate (72) drives the second rack (71) to move, the second rack (71) drives the second gear (705) to rotate, the second gear (705) drives the second rotating shaft (703) and the sleeve (702) to rotate, and then the third electric telescopic rod (708) drives the sliding plate (707) to move, the sliding plate (707) drives The movable plate (78) is moved, and the movable plate (78) drives the marking pen (74) to move. When the marking pen (74) moves to the top of the output end (13) to be marked, the second electric telescopic rod (76) drives the connecting plate (75) to move downward, and the connecting plate (75) drives the marking pen (74) to move downward and contact the output end (13). Then, the driving motor (79) drives the driving gear (700) to rotate, and the driving gear (700) drives the driven gear (701) to rotate. The driven gear (701) drives the first rotating shaft (77) to rotate, and the first rotating shaft (77) drives the connecting plate (75) to rotate. The connecting plate (75) drives the marking pen (74) to rotate, so that a circle can be drawn on the output end (13), thereby realizing the marking function, and facilitating the maintenance and inspection of unqualified channels by staff.
