Abstract: An assembly of electronic components providing means for reception of data using an optical fibre wherein said assembly comprises: a photodiode; an amplifier coupled to said photodiode a printed circuit board, said photodiode and amplifier physically mounted on a first side of said printed circuit board; and a stiffener attached to said printed circuit board, wherein said stiffener is attached in a region approximately concentric with said region of said printed circuit board whereon said photodiode and amplifier are mounted, and conducting bond wires configured to directly couple said amplifier and said photodiode to conducting traces on a second opposite side of said printed circuit board with respect to said amplifier and said photodiode; and a fibre alignment ferrule and lens cap assembly, wherein said fibre alignment ferrule and lens cap assembly comprises: a ferrule which is configured to configured to provide a receptacle with defined physical alignment for an optical fibre; a lens which is configured

Abstract: A construction and configuration for the receiving function of a high speed optical communication system with reduced manufacturing cost and improved performance. In an aspect, mounting the cover and lens provides a self-alignment behaviour that advantageously positions the cover and the lens to be in the optimum position for the photodiode. An assembly of electronic components receives data using an optical fibre. In one aspect, the assembly includes a photodiode, an amplifier coupled to the photodiode, and a printed circuit board on which the photodiode and amplifier are physically mounted, The printed circuit board has areas of a first material to which components may be attached using a fixing agent, and areas of a second material to which components will not attach using the fixing agent. Conductive bond wires are configured to directly couple the amplifier and the photodiode to conductive traces on an opposite side of the printed circuit board.
