Abstract
An electro-optical transducer assembly for translating between an optical high speed serial data transmission path and parallel electrical data transmission paths is provided by a light emitting or light detecting device with serial terminals, a logic chip with timing, amplifying, serializing or de-serializing circuitry, and a multi-layer coupling chip with parallel input or output contacts mounted between the device and the logic chip for coupling the serial terminals of the device to the serial terminals on the logic chip and coupling the logic chip parallel terminals to the parallel input or output contacts.
