An optical data transmission module and a computer including the optical data transmission module, an optical transceiver and a transceiver module for wireless data communication,

摘要

An optical transmitter and transceiver module for data communication is disclosed. These transceiver modules include an array of light emitting diodes arranged in a regular and symmetrical manner on a mounting base 140 in a dome-shaped housing 142. The housing 142 includes diffuser means for source magnification. In addition to the transmitter portion comprised of the diodes, the transceiver module includes a receiver. The receiver has four photodiodes 143 arranged under the device base 140. These photodiodes are tilted and face various directions to receive light from all directions of the module. These photodiodes are protected by a fine wire mesh 145 that acts as a Faraday cage for the reduction of electromagnetic interference. The SMD-technology substrate 144 for electronic circuits is located directly below the photodiode 143.
