Abstract
An optical transmission repeater with high operational reliability comprises of a plurality of light sources for transmitting an optical energy into an optical fiber, an optical connector for introducing the optical energy from each of said light sources to an optical transmission line, and a switching circuit for selectively operating only one light source. When a light source in operation is deteriorated, the light source in operation is switched to another light source by said switch. Thus, high operational reliability of an optical repeater is obtained although each of light sources have a low operational reliability.
