Abstract: In an optical transmission apparatus in which a plurality of nodes are optically connected to one another via an optical transmission path, a light signal which is coded so that a mixture ratio of 1 and 0 constituting data is made close to 50% is transmitted through the optical transmission path. When a light signal is not emitted from all of the nodes, a dummy signal which is an AC-like signal is emitted to the optical transmission path. Therefore, an optoelectric conversion section can be always set to an active state, and the signal recognizability can be prevented from being lowered.

Abstract: A light-emitting device includes 16 vertical-cavity surface-emitting laser diodes (VCSELs) disposed like a 4×4 grid, for example, in a sufficiently narrower range than the end surface of an optical fiber. The 16 VCSELs disposed in the light-emitting device emit optical signals in the same direction. Since the VCSELs are disposed with a concentration in the sufficiently narrower range than the end surface of the optical fiber as described above, if the optical signals emitted from the VCSELs are spread, almost all optical signals generated by the light-emitting device are incident on the end surface of the optical fiber and are transmitted through the optical fiber.
