OPTICAL MODULE, COMMUNICATIONS DEVICE, AND POE DEVICE

An optical module, a communication device, and a PoE device are provided. The optical module includes a housing (1), an optical component (2), and a power supply component (3). The housing (1) is provided with 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. Both the optical-to-electrical conversion component (22) and the power supply line (32) are located in the housing (1), the first optical connector (21) is located in the first socket (11), a part that is of the first electrical connector (31) and that is exposed from the housing (1) is located at any position at the first end of the housing (1); and both the second optical connector (23) and the first electrical connector (33) are located in the second socket (12). The first socket (11) is configured to insert a composite cable that matches the optical module. A power connector of the 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 panel space of the communication device can be reduced, and minimization development of the communication device is facilitated.
