Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing instrument technology, and in particular to an optical power meter with a line-finding function. Background Technology
[0002] With the popularization and integration of fiber optic communication technology and Ethernet technology, the physical layer of modern communication networks (such as FTTH fiber-to-the-home, enterprise campus networks, data centers, etc.) usually includes a complex structure with a mixed deployment of optical fiber and copper cable (such as twisted pair). In the construction, acceptance, maintenance and troubleshooting of such networks, optical power meters and network cable finders are two of the most commonly used basic and critical portable testing tools by technicians.
[0003] An optical power meter is a core measuring instrument in the field of optical communication. Its function is to accurately measure the absolute power value of optical signals in an optical fiber link or to assess the loss of a section of optical fiber link. It converts optical signals into electrical signals through a photodetector, and then displays the results visually after processing. Technicians rely on optical power meters to verify the output power of optical transmitting equipment, assess the insertion loss of optical fiber connections, and confirm whether the optical power at the receiving end is within the threshold range for normal system operation. It is an indispensable device for ensuring the transmission quality of optical communication links.
[0004] A network cable tracer is a practical tool in the field of network cabling, primarily used to quickly and accurately identify and locate specific copper or fiber optic lines in complex cable bundles or patch panels. Its typical operating mode involves a transmitter applying a unique pulse-modulated signal to the target cable pair. Technicians then use a receiver with an induction probe or a direct-connect adapter to detect this signal and non-destructively "trace" the target line from among multiple cables, thus completing tasks such as line verification and fault location.
[0005] However, in current network operation and maintenance practices, the two types of equipment mentioned above are completely independent in terms of technology, product form, and usage process. This separation has brought about many practical problems and efficiency bottlenecks: When performing complex tasks (such as troubleshooting a fault involving both fiber optic transceivers and Ethernet switch ports), technicians must carry two separate sets of equipment: an optical power meter and a network cable finder. This not only increases the cost of equipment procurement, battery management, and maintenance, but also adds to the burden on field personnel, especially in situations involving high altitudes, confined spaces, or long-distance outdoor work.
[0006] In practice, technicians often need to frequently switch between two devices. For example, when troubleshooting a link that converts a fiber optic transceiver to an Ethernet signal, they may first need to use an optical power meter to check if the optical power of the fiber optic link is normal, and then use a network cable finder to locate the corresponding twisted pair cable at the switch end. This process of repeatedly picking up, connecting, and switching devices disrupts the workflow and significantly reduces the overall efficiency of troubleshooting and maintenance. Utility Model Content
[0007] Based on the above, the purpose of this utility model is to provide an optical power meter with a line locator function, which can realize the functions of accurate optical power measurement and rapid network line locator on a single device.
[0008] To achieve the above objectives, the present invention adopts the following technical solution: This utility model provides an optical power meter with a line finder function, comprising: The first housing has a first circuit board inside, on which an optical power meter module, a network cable finder transmitter module, a first indicator light, a first display screen, a first control button and a first power supply are integrated. The second housing contains a second circuit board, which integrates a network cable finder module, a second indicator light, a second control button, and a second power supply. The first housing has a slot on its rear side, and the second housing is assembled into the slot.
[0009] Preferably, the openings on the rear and top of the first housing form the slot.
[0010] Preferably, the bottom of the slot is provided with a first positioning groove, and the bottom of the second housing is provided with a second positioning plate, which can be inserted into the first positioning groove.
[0011] Preferably, the side of the slot is provided with a second positioning groove, and the side of the second housing is provided with a corresponding elastic second positioning protrusion, which can be engaged in the positioning groove.
[0012] Preferably, the optical power meter module is located at the top of the housing, and the optical power meter module includes an optical emission port and an optical power interface.
[0013] Preferably, a cover plate is rotatably provided on the top of the housing, and the cover plate can be flipped open to expose the light emission port and the optical power interface.
[0014] Preferably, a charging port is provided on the side of the housing.
[0015] Preferably, the network cable finder transmitting module is disposed at the bottom of the housing, and the network cable finder transmitting module includes a first network cable interface.
[0016] Preferably, the first housing includes a first front housing and a first rear housing, which are detachably connected.
[0017] Preferably, the second housing includes a second front housing and a second rear housing, and the second front housing and the second rear housing are detachably connected; The network cable finder receiving module includes a sensing probe and a second network cable interface. The sensing probe is located at the top of the second housing, and the second network cable interface is located at the bottom of the second housing.
[0018] The beneficial effects of this utility model are as follows: (1) This utility model integrates an optical power meter and a network cable finder into a single combinable device. Technicians only need to carry this single device to handle optical power testing of fiber optic links and cable finding, pairing and crimping of network lines. This solves the pain points of high procurement costs, heavy carrying burden and cumbersome battery and accessory management caused by the previous need to carry, manage and maintain two separate devices. It is especially suitable for field, outdoor and mobile operations.
[0019] (2) Through the slot-mountable structure, the second housing can be assembled onto the first housing as needed to form a compact integrated device that is easy to carry and store; when the network cable finder receiver module is needed, it can be taken out from the slot and used as an independent cable finder receiver module.
[0020] (3) When conducting comprehensive troubleshooting of optical and electrical hybrid links, technicians do not need to repeatedly switch, connect and operate between the two types of equipment. After checking the optical power of the fiber optic link, the same equipment can be used immediately to perform the function of a network cable finder. The workflow is seamlessly connected, which greatly reduces the operation interruption time, speeds up troubleshooting, and improves the overall efficiency of operation and maintenance.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0028] like Figures 1 to 7 As shown in the figure, this utility model embodiment provides an optical power meter with a line finder function, which mainly includes a first housing 1 and a second housing 2.
[0029] The first housing 1 constitutes the main unit of the device. Please refer to... Figure 4 and Figure 5 It contains a first circuit board 11. The first circuit board 11 integrates an optical power meter module 111, a network cable finder transmitter module, a first power supply (not shown), a first control button 114, a first display screen 115, and a first indicator light 116.
[0030] The optical power meter module 111 is used to realize optical power measurement. It includes an optical emission port 1111 for emitting visible light (such as red light) for coarse measurement of optical fiber continuity, and an optical power interface 1112 for connecting to the optical fiber connector under test to convert the optical signal into an electrical signal for precise measurement.
[0031] The network cable tracer transmitter module 112 is used to generate specific pulse modulation signals. The network cable tracer transmitter module 112 is provided with two first network cable interfaces 1121 (such as RJ45 interfaces), which can inject signals into the network cable that needs to be traced.
[0032] The first display screen 115 (such as an LCD screen) is used to display the detection information of the measured optical power.
[0033] The first control button 114 is used for function selection, parameter setting, etc.
[0034] The first indicator light 116 is used to display the working status and the results of network cable finding, pairing, or clamping.
[0035] The primary power source is typically a rechargeable lithium battery, located on the rear side of the first circuit board 11, which powers all electronic modules within the first housing 1. A universal charging interface 113 (such as a Type-C interface) is also provided on the side of the first housing 1 for charging the primary power source.
[0036] like Figures 4 to 6 As shown, the optical power meter module 111 is preferably located on the top of the first housing 1. A cover plate 12 is rotatably mounted on the top of the first housing 1 via a pivot. The cover plate 12 can be closed when not in use, effectively protecting the optical emission port 1111 and optical power interface 1112 of the optical power meter module 111 from dust contamination or physical impact; when in use, it can be flipped open to expose the interface for easy operation. The network cable finder transmitter module 112 is located at the bottom of the first housing 1, with its first network cable interface 1121 facing downwards or to the side for easy cable connection. The first housing 1 itself is composed of a first front housing 13 and a first rear housing 14, which are detachably connected by screws or other fasteners, facilitating internal assembly and maintenance.
[0037] The second housing 2 constitutes an independent network cable finder receiving module. For example... Figure 3 , Figure 4 and Figure 7 As shown, it has a second circuit board 21 inside, which integrates a network cable finder receiver module 211, a second indicator light 212, a second control button 213, and a second power supply 214.
[0038] The network cable finder receiving module 211 receives and processes signals from the transmitting module. It includes a sensing probe 2111, which is placed on the top of the second housing 2 for non-contact cable finding, and a second network cable interface 2112 (such as an RJ45 interface), which is located at the bottom of the housing for contact pairing or crimping tests.
[0039] The second indicator light 212 is used to display the signal strength.
[0040] The second control button 213 is used for powering on / off and switching modes.
[0041] The second power supply 214 provides independent power to the circuit inside the second housing 2, ensuring that it can work independently after separation. The second power supply 214 is preferably a removable AA or AAA battery.
[0042] The second housing 2 also adopts a split structure, which is formed by the detachable connection of the second front housing 22 and the second rear housing 23.
[0043] like Figure 2 , Figure 3 and Figure 4 As shown, a slot 15 is formed on the rear side of the first housing 1 through its rear sidewall and the opening at the top. The size and shape of the second housing 2 are designed so that it can be tightly fitted into this slot 15.
[0044] To ensure stable and accurate assembly and ease of user operation, a first positioning groove 151 is provided at the bottom of the slot 15. Correspondingly, a second positioning plate 24 extends from the bottom of the second housing 2. When the equipment needs to be assembled, the user aligns the second positioning plate 24 at the bottom of the second housing 2 and inserts it into the first positioning groove 151 to achieve initial longitudinal positioning and guidance.
[0045] A second positioning groove 152 is provided on the side of the slot 15. A corresponding elastic second positioning protrusion 25 is provided on the side of the second housing 2. This protrusion may contain a spring steel ball or an inclined latch structure made of elastic plastic. When the second housing 2 is pushed into the slot 15 along the first positioning groove 151 to the predetermined position, the elastic second positioning protrusion 25 on the side will click into the second positioning groove 152, thus firmly locking the two housings together and preventing accidental detachment. When separation is required, the user simply pulls the second housing 2 outwards to overcome the resistance of the elastic latch and removes it.
[0046] In this invention, during routine inspections or while traveling to the work site, the user can assemble the second housing 2 into the slot 15 of the first housing 1, forming a compact, easy-to-handle, and easily stored single device. When fiber optic testing is required, the user can open the cover 12 and connect the fiber optic cable to the optical power interface 1112 to measure optical power or optical loss. When network tracing, pairing, or crimping tests are needed during operation, the user can easily remove the second housing 2 from the slot 15 for use. The entire process requires no equipment replacement, achieving a seamless connection from optical layer to electrical layer fault diagnosis.
[0047] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
