OPTICAL MODULE FOR TRANSMITTING OPTICAL SIGNAL

摘要

An optical module comprises: a housing; a first incident surface mounted on the housing for receiving an optical signal converted from an electrical signal; a first output surface mounted on the housing for exporting the optical signal from the first incident surface; a second incident surface mounted on the housing for receiving another optical signal to be converted to another electrical signal; and a second output surface mounted on the housing for exporting the another optical signal from the second incident surface. An aperture of the first incident surface is smaller than an aperture of the second incident surface.
