Abstract: An optical module includes a housing, an optical component, and a power supply component. The housing has a first socket and a second socket. The optical component includes a first optical connector, an optical-to-electrical conversion component, and a second optical connector that are sequentially connected. The power supply component includes a first electrical connector, a power supply line, and a second electrical connector that are sequentially connected. The optical-to-electrical conversion component and the power supply line are both located in the housing, the first optical connector is located in the first socket, the first electrical connector is located at the first socket, and the second optical connector and the second electrical connector are both located in the second socket.

Abstract: This disclosure provides an encryption/decryption system, an optical module, and a related apparatus and system, and belongs to the field of network communications technologies. The encryption/decryption system includes an encryption/decryption component, a first interface component, and a second interface component. The encryption/decryption component is configured to encrypt a first physical layer data stream from the first interface component and transmit the encrypted first physical layer data stream to the second interface component, and is configured to decrypt a second physical layer data stream from the second interface component and transmit the decrypted second physical layer data stream to the first interface component. According to this disclosure, a delay caused by encryption/decryption during data transmission can be reduced.

Abstract: An optical module includes a housing, an optical component, and a power supply component. The housing is provided with a first socket and a second socket. The optical component includes a first optical connector, an optical-to-electrical conversion component, and a second optical connector that are sequentially connected.

Abstract: An optical module includes a housing, an optical component, and a power supply component. A second end of the housing is provided with a second socket, and the second end of the housing is an end part configured to be inserted into an optical communication device. The optical component includes a second optical connector, and the power supply component includes a second electrical connector. Both the optical component and the power supply component are located in the housing, both the second optical connector and the second electrical connector are located in the second socket, and positions of the second optical connector and the second electrical connector are independent of each other.

Abstract: An optical module, a communication device, and a Power over Ethernet (PoE) device are provided. The optical module includes a housing, an optical component, and a power supply component. The housing has a first socket and a second socket. The optical component also includes a first optical connector, an optical-to-electrical conversion component, and a second optical connector that are sequentially connected. The power supply component includes a first electrical connector, a power supply line, and a second electrical connector that are sequentially connected. The first socket is configured to insert a composite cable that matches the optical module. A power connector of the composite cable can be connected to the communication device by using the optical module, and the power connector of the composite cable does not need to be inserted into the communication device, so that panel space of the communication device can be reduced and miniaturization facilitated.
