OPTICAL MODULE, COMMUNICATION DEVICE, AND POE DEVICE

An optical module, a communication device, and a PoE device are provided, and pertain to the field of optical communication technologies. The optical module includes a housing (1), an optical component (2), and a power supply component (3). The housing (1) has a first socket (11) and a second socket (12). The optical component (2) includes a first optical connector (21), an optical-to-electrical conversion component (22), and a second optical connector (23) that are sequentially connected. The power supply component (3) includes a first electrical connector (31), a power supply line (32), and a second electrical connector (33) that are sequentially connected. The optical-to-electrical conversion component (22) and the power supply line (32) are both located in the housing (1), the first optical connector (21) is located in the first socket (11), the first electrical connector (31) is located at the first socket (11), and the second optical connector (23) and the second electrical connector (33) are both located in the second socket (12). The first socket (11) is configured to insert a cable, the second socket (12) is configured to be inserted into the communication device, and the optical module is any one of a standard optical module packaging type. A power connector of a composite cable is electrically 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 miniaturization development of the communication device is facilitated.
