LIGHT TRANSMISSION/RECEPTION MODULE

摘要

PROBLEM TO BE SOLVED: To prevent the near-end crosstalk of transmission signal light from a light-emitting device to a light receiving element that causes troubles in a light transmission/reception module that is applied to a two-way optical communication system. SOLUTION: In the light transmission/reception module for packaging a light-emitting device and a light receiving element to the same package, an absorption film is formed around a transparent body at a window section so that transmission signal light from the light-emitting device does not become stray light in the light transmission/reception module.
