In the optical communication technology, in order to establish information transfer between information processing apparatuses, it is necessary to load information onto light, and transfer of information is realized by propagation of light. Here, the light loaded with information is an optical signal. The optical signal can reduce the loss of optical power when transmitted in the information transmission device, so that high-speed, long-distance and low-cost information transmission can be realized. The signal that the information processing apparatus can recognize and process is an electrical signal. Information processing devices typically include optical network terminals (Optical Network Unit, ONUs), gateways, routers, switches, handsets, computers, servers, tablets, televisions, etc., and information transmission devices typically include optical fibers, optical waveguides, etc.

The optical module can realize the mutual conversion of optical signals and electric signals between the information processing equipment and the information transmission equipment. For example, 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; the optical module converts the first optical signal into a first electrical signal and transmits the first electrical signal to an optical network terminal; the second electrical signal from the optical network terminal is transmitted to the optical module, which converts the second electrical signal into a second optical signal and transmits the second optical signal to the optical fiber. Since information transmission can be performed between the plurality of information processing apparatuses by an electric signal, it is necessary that at least one of the plurality of information processing apparatuses is directly connected to the optical module, and it is unnecessary that all of the information processing apparatuses are directly connected to the optical module. Here, the information processing apparatus directly connected to the optical module is referred to as an upper computer of the optical module. In addition, the optical signal input or the optical signal output of the optical module may be referred to as an optical port, and the electrical signal input or the electrical signal output of the optical module may be referred to as an electrical port.

As shown in fig. 1, the optical communication system mainly includes a remote information processing apparatus 1000, a local information processing apparatus 2000, a host computer 100, an optical module 200, an optical fiber 101, and a network cable 103.

One end of the optical fiber 101 extends in the direction of the remote information processing apparatus 1000, and the other end of the optical fiber 101 is connected to the optical module 200 through an optical port of the optical module 200. The optical signal may be totally reflected in the optical fiber 101, and the propagation of the optical signal in the direction of total reflection may almost maintain the original optical power, and the optical signal may be totally reflected in the optical fiber 101 a plurality of times to transmit the optical signal from the remote information processing apparatus 1000 into the optical module 200, or transmit the optical signal from the optical module 200 to the remote information processing apparatus 1000, thereby realizing remote, low power loss information transfer.

The optical communication system may include one or more optical fibers 101, and the optical fibers 101 are detachably connected, or fixedly connected, with the optical module 200.

The optical module interface 102 is configured to access the optical module 200, so that the host computer 100 and the optical module 200 establish a unidirectional or bidirectional electrical signal connection.

The upper computer 100 further includes an external electrical interface, which may access an electrical signal network. For example, the pair of external electrical interfaces includes a universal serial bus interface (Universal Serial Bus, USB) or a network cable interface 104, and the network cable interface 104 is configured to access the network cable 103 so as to establish a unidirectional or bidirectional electrical signal connection between the host computer 100 and the network cable 103. One end of the network cable 103 is connected to the local information processing apparatus 2000, and the other end of the network cable 103 is connected to the host computer 100, so that an electrical signal connection is established between the local information processing apparatus 2000 and the host computer 100 through the network cable 103. For example, the third electrical signal sent by the local information processing apparatus 2000 is transmitted to the upper computer 100 through the network cable 103, the upper computer 100 generates a second electrical signal according to the third electrical signal, the second electrical signal from the upper computer 100 is transmitted to the optical module 200, the optical module 200 converts the second electrical signal into a second optical signal, and the second optical signal is transmitted to the optical fiber 101, where the second optical signal is transmitted to the remote information processing apparatus 1000 in the optical fiber 101. For example, a first optical signal from the remote information processing apparatus 1000 propagates through the optical fiber 101, the first optical signal from the optical fiber 101 is transmitted to the optical module 200, the optical module 200 converts the first optical signal into a first electrical signal, the optical module 200 transmits the first electrical signal to the host computer 100, the host computer 100 generates a fourth electrical signal from the first electrical signal, and the fourth electrical signal is transmitted to the local information processing apparatus 2000. The optical module is a tool for realizing the mutual conversion between the optical signal and the electric signal, and the information is not changed in the conversion process of the optical signal and the electric signal, and the coding and decoding modes of the information can be changed.

The direction in which the connection lines of the two openings 203 and 204 are located may be identical to the longitudinal direction of the optical module 200 or may be inconsistent with the longitudinal direction of the optical module 200. For example, opening 203 is located at the end of light module 200 (left end of fig. 3), and opening 204 is also located at the end of light module 200 (right end of fig. 3). Alternatively, the opening 203 is located at the end of the light module 200, while the opening 204 is located at the side of the light module 200.

When the optical module 200 is inserted into the cage 106, the optical module 200 is fixed in the cage 106 by the engaging part of the unlocking part 600; when the unlocking member 600 is pulled, the engaging member of the unlocking member 600 moves along with the unlocking member, so that the connection relationship between the engaging member and the host computer is changed, and the fixation between the optical module 200 and the host computer is released, so that the optical module 200 can be pulled out from the cage 106.
