ABSTRACT:
A multichannel optical communication module includes: a board, and a signal-converting element having optical-action points aligned with a first pitch to emit and receive signal light. The element performs conversion between an optical signal and an electric signal at each of the optical-action points. The module further includes an optical waveguide that includes optical waveguide cores each having a first and a second optical-signal ends that are opposed to each other. The first optical-signal ends are aligned with the first pitch and optically connected to the respective optical-action points, while the second optical-signal ends are aligned with a second pitch longer than the first pitch. The module further includes a coupling component fixed on the board and coupling, to the module, an optical connector that holds ends of optical fibers aligned with a pitch equal to the second pitch, thereby optically connecting the second optical-signal ends to the optical fibers.
