Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a device for detecting and cleaning an end face of an optical module. Background Art

[0002] New services and applications such as cloud computing, mobile internet, and video all utilize optical communication technology. In optical communications, optical modules are tools for converting optical and electrical signals and are key components in optical communication equipment.

[0003] As optical modules evolve toward higher speeds, integration, and intelligence, their reliability becomes increasingly important. With the rapid development of 5G and AI technologies, the quality requirements for optical modules are becoming increasingly stringent. The manufacturing of optical modules involves cleaning and inspecting LC and MTP end faces. Dirt or damage to the fiber end faces at the optical port of an optical module directly impacts the product's optical transceiver performance, leading to a decrease in yield.

[0004] Currently, cleaning equipment cleans fiber ports, but after cleaning, optical modules must be manually transferred to an inspection machine for surface testing. If the cleaning effect is poor, the optical module must be cleaned again. Therefore, the cleaning and testing processes for optical modules are handled separately, resulting in low efficiency and an inability to guarantee product quality. Utility Model Content

However, the described embodiments are only some embodiments of the present disclosure, not all embodiments. Based on the embodiments provided in the present disclosure, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present disclosure.

[0069] Unless otherwise required by context, the term "comprises" is interpreted to mean "including, but not limited to" throughout the specification and claims; the terms "first", "second", etc. are not intended to imply relative importance or an upper limit on the number thereof; the term "multiple" means two or more; the term "connected" should be interpreted broadly, for example, "connected" can be fixedly connected, or detachably connected, or integrated, can be directly connected, or indirectly connected through an intermediate medium; the use of the terms "adapted to" or "configured to" means open and inclusive language, which does not exclude devices adapted to or configured to perform additional tasks or steps; the terms "parallel", "vertical", "same", "consistent", "flush", etc. are not limited to absolute mathematical relationships, but also include acceptable error ranges generated in practice, and differences formed based on the same design concept but due to manufacturing reasons.

[0070] In optical communication technology, in order to establish information transmission between information processing devices, information is loaded onto light, and the transmission of information is carried out by using the propagation speed of light. Such information-loaded light is an optical signal. The optical signal can reduce the loss of optical power when transmitted in an optical information transmission device, and realize long-distance transmission of the optical signal. At the same time, the cost of optical information transmission devices such as optical fibers is lower than that of electrical information transmission devices such as copper wires. Therefore, optical communication technology can realize high-speed, long-distance, and low-cost information transmission.

[0071] An information processing device generally includes an optical network unit (ONU), a gateway, a router, a switch, a mobile phone, a computer, a server, a tablet computer, a television, etc., and an optical information transmission device generally includes an optical fiber and an optical waveguide, etc. The signal capable of being recognized and processed by the information processing device is an electrical signal, and the optical communication technology adopts an optical signal for transmission, which requires an optical module to convert the optical signal and the electrical signal.

[0072] The optical module can realize the mutual conversion between the optical signal and the electrical signal between the information processing device and the optical information transmission device. In some embodiments, at least one of the optical signal input end or the optical signal output end of the optical module is connected with an optical fiber, and at least one of the electrical signal input end or the electrical signal output end of the optical module is connected with an optical network unit; a first optical signal from the optical fiber is transmitted to the optical module, the optical module converts the first optical signal into a first electrical signal, and transmits the first electrical signal to the optical network unit; a second electrical signal from the optical network unit is transmitted to the optical module, the optical module converts the second electrical signal into a second optical signal, and transmits the second optical signal to the optical fiber.

[0073] Since the information transmission between multiple information processing devices can be performed through electrical signals, at least one of the multiple information processing devices needs to be directly connected with the optical module, without the need for all the information processing devices to be directly connected with the optical module.
