Abstract
An optical module, including: a first laser and a first laser chip for driving the first laser; a second laser and a second laser chip for driving the second laser; and a multi-layer circuit board, including a surface layer, a reference layer, and an intermediate layer provided between the surface layer and the reference layer, where a first row of edge connector pins and a second row of edge connector pins are disposed in at least one surface layer; the first row of edge connector pins are disposed to be closer than the second row of edge connector pins to a side edge, of the multi-layer circuit board, that is provided with an edge connector; and a region, of the intermediate layer, that corresponds to a data signal line pin in the second row of edge connector pins is a hollow region.
