Abstract:
1. A multichannel optical communication module comprising: a board; a signal-converting element that has a plurality of optical-action points aligned with a predetermined first pitch to emit and receive signal light and performs conversion between an optical signal and an electric signal at each of the optical-action points; an optical waveguide that includes a plurality of optical waveguide cores each having a first optical-signal end and a second optical-signal end that are opposed to each other, the first optical-signal ends being aligned with a first pitch and optically connected to the respective optical-action points, while the second optical-signal ends being aligned with a second pitch, wherein the second pitch in a direction parallel to the board is longer than the first pitch in the direction parallel to the board; and an optical-connector coupling component that is fixed on the board and couples, to the module, an optical connector that holds ends of a plurality of optical fibers aligned with a pitch equal to the second pitch, thereby optically connecting the second optical-signal ends to the optical fibers, wherein the first pitch is about 250 μm.
