Abstract
An optical composite module includes a housing having two opposing side surfaces, a light separating unit disposed in the housing and adapted to separate pumping light and signal light, optical fibers respectively mounted on the opposing side surfaces of the housing to cause the signal light to pass through the light separating unit on a substantially straight line, and a pumping light source unit disposed in the housing and adapted to cause the pumping light to be incident on the light separating unit. This optical composite module can reduce a loss of light and improve the utilization efficiency of pumping light.
