Description

Technical Field

[0001] This utility model relates to the field of communication cable testing technology, specifically to an optical fiber tester for router inspection. Background Technology

[0002] Broadband network access lines typically consist of the incoming fiber optic cable connecting the single-end optical transceiver and an eight-core UTP twisted-pair cable connecting the transceiver and the router. When communication is interrupted or unreliable, the fiber optic cable and twisted-pair cable should generally be checked first before determining if the router itself is faulty. Existing fiber optic testers can only test the incoming fiber optic cable; testing the twisted-pair cable requires a separate, less frequently used cable tester (main and auxiliary units), or troubleshooting by replacing the cable. This setup is inconvenient for both technicians and users, making the testing process more complex. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a fiber optic tester for router inspection, which, while having the traditional fiber optic testing function, adds a twisted-pair testing function, and integrates this function into the instrument body, so that it can perform comprehensive testing on the upstream and downstream fiber optic cables and input and output twisted-pair cables of the router's communication path, and is widely applicable to on-site repair or home self-testing equipment.

[0004] This fiber optic tester for router inspection includes a housing and a main control board housed within the housing. The front of the housing features a display screen, control buttons, and eight indicator lights corresponding to eight-core twisted-pair cables. The top of the housing has a pair of fiber optic SC interfaces for fiber optic testing, and one side of the housing has a twisted-pair RJ45 interface for twisted-pair testing. A light source module is detachably installed at the bottom of the housing, and the light source module houses a secondary control board. The main control board integrates a first red light source emitting module, first and second optical signal receiving modules, an optical power module, a display and button driver module, a serially connected main MCU processor, a first wireless module, a storage module, and a main power supply module. The secondary control board integrates a second red light source emitting module, a serially connected secondary MCU processor, a second wireless module, and a secondary power supply module. The first and second wireless modules communicate wirelessly.

[0005] Specifically, the fiber optic SC interface includes a first SC interface and a second SC interface on the top two sides of the housing for transmitting test red light and receiving optical signals, respectively. The twisted-pair RJ45 interface includes a first RJ45 interface on the side of the housing for receiving optical signals and a second RJ45 interface on the light source module for transmitting twisted-pair test red light.

[0006] Furthermore, the output of the main MCU processor is connected to the first SC interface via the optical power module and the first red light source emitting module, and the input of the MCU processor is connected to the second SC interface via the first optical signal receiving module; the first RJ45 interface is connected to the input of the main MCU processor, and the output of the main MCU processor is connected to an indicator light; the display and button driving module is serially connected to the main MCU processor, and the display screen and control buttons are respectively integrated on the display and button driving module; the main power module supplies power to the first red light source emitting module, the display and button driving module, the main MCU processor, and the first wireless module.

[0007] Furthermore, the second RJ45 interface is connected to the input terminal of the secondary MCU processor via the second red light source emitting module. The second red light source emitting module and the secondary power supply module provide power to the MCU processor and the second wireless module.

[0008] Specifically, both the main and secondary MCU processors use the MT6737 MCU processing circuit module.

[0009] The optimized version has an adhesive protective layer attached to the outer periphery of the side of the housing.
