Abstract: the optical transmission module provided is designed to be simpler, smaller, and faster. it consists of a housing that holds one or more stacked substrates, partially exposed. inside the housing, there is a light emitter that generates optical signals and an optical functional element that processes the transmission signal for driving the light emitter. multiple terminals extend from the inside to the outside of the housing on the substrates. the terminals are divided into two groups: the first group connects to electrodes of a high-frequency circuit in the optical functional element, and the second group connects to electrodes of a low-frequency circuit. the length between the upper surfaces of the first group terminals and the high-frequency circuit electrodes is shorter than the length between the upper surfaces of the second group terminals and the low-frequency circuit electrodes, in the direction perpendicular to the substrates' major surface.
