However, the described embodiments are merely some, and not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments provided in this disclosure are within the scope of protection of this disclosure.

[0061] Unless otherwise required by context, the term "include" is to be interpreted as an open, inclusive meaning, i.e. "including, but not limited to"; the terms "first", "second" are not to be interpreted as indicating or implying relative importance or indicating a limit to the number of items; the term "multiple" means two or more; the term "connected" is to 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 or configured to perform additional tasks or steps; the terms "parallel", "vertical", "same", "consistent", "flush" and the like are not limited to absolute mathematical relationships, but also include acceptable error ranges generated in practice, and also include differences based on the same design concept but due to manufacturing reasons.

[0062] 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.

[0063] Information processing devices generally include optical network terminals (ONUs), gateways, routers, switches, mobile phones, computers, servers, tablets, televisions, etc., and optical information transmission devices generally include optical fibers and optical waveguides, etc. The signal that can be recognized and processed by the information processing device is an electrical signal, while the optical communication technology uses an optical signal for transmission, which requires an optical module to convert the optical signal and the electrical signal.

[0064] 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 terminal; 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 terminal; a second electrical signal from the optical network terminal 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.

[0065] Since information can be transmitted between multiple information processing devices through electrical signals, at least one of the multiple information processing devices needs to be directly connected to the optical module, without all the information processing devices being directly connected to the optical module. Here, the information processing device directly connected to the optical module is also referred to as the host computer of the optical module. In addition, the optical signal input end or the optical signal output end of the optical module is referred to as the optical port, and the electrical signal input end or the electrical signal output end of the optical module is referred to as the electrical port.
