The application provides an optical network apparatus and an optical module. The optical network apparatus is configured to: convert, by a processing chip, the received N electrical signals from a board interface chip into a first electrical signal and a second electrical signal; and send the above two electrical signals to a first optical transmission component and a second optical transmission component, respectively; convert, by the first optical transmission component, the first electrical signal into a first optical signal; and convert, by the second optical transmission component, the second electrical signal into a second optical signal. The N to-be-sent electrical signals are combined, and only two optical transmission components are connected to the processing chip. Therefore, the processing chip does not need to be connected to four optical transmission components, fewer optical transmission components are required, and costs are reduced.
