Abstract
Abstract An optical transmission module includes plural optical transmission means (optical waveguides) whose end portions are exposed on a first end face thereof, and at least one of an optical transmitting section and an optical receiving section to each of which some of the optical transmission means are optically coupled. The remaining optical transmission means are exposed on a second end face opposed to the first end face. Only some of the plural optical transmission means are designed to have a communication facility at some position in the longitudinal direction thereof, while the remaining optical transmission means are designed to have the communication facility by being connected to post-stage optical transmission modules in the longitudinal direction. By multistage-connecting these optical transmission modules, plural optical transmission means and optical transmission modules can be collectively connected at a narrow frontage.
