Abstract
In an optical transmit-receive module, an optical fiber plug connected with an optical fiber for optical transmission is removably inserted in a housing. Within the housing, there are provided a branching type light guide, and an optical semiconductor device giving an optical signal to the branching type light guide and receiving an optical signal from the branching type light guide. When the optical fiber plug is inserted in the housing, it is optically connected with the branching type light guide through a light-permeable member having a refractive index approximately equal to refractive indices of the optical fiber and the branching type light guide.
