Abstract

A transceiver, especially an infrared transceiver, has a flat surface section and at least one or two lens forming housing sections integrally formed with the flat housing section. The lens housing sections are positioned so that one flat surface of the flat housing extends tangentially to the lens housing section or sections while the latter project outside the opposite flat housing surface. The lens housing section or sections are positioned along an edge of the flat housing section. For this purpose the lens forming housing section or sections have a substantially larger diameter (D) than the thickness (d) of the flat housing section. The respective lenses thus may have a substantially larger aperture, thereby increasing the wireless transmission and reception range of optical data transmission signals, in accordance with IRDA standards.
