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.
