Abstract
An assembly of electronic components for reception of data using an optical fibre wherein said assembly comprises: a photodiode; a first amplifier coupled to said photodiode; a second amplifier, whose electrical behaviour is substantially identical to an electrical behaviour of said first amplifier; an impedance network comprising at least two electronic components coupled between an input of said second amplifier and a reference terminal, wherein those at least two electronic components comprise at least two impedance elements, one impedance element being capacitive and another being resistive or inductive, and wherein said at least two electronic components are adjustable under electronic control to adjust the impedance presented by said impedance network; and circuitry for creating a signal formed from a subtraction of outputs of the first and second amplifiers.
