Dual-protocol optoelectronic interface

An optoelectronic interface (2) arranged to be connected to an optical fibre on which incoming light signals comprising specific light signals can travel, said specific light signals being defined according to a single specific communication protocol among a plurality of predefined communication protocols, each using a different carrier signal wavelength, the optoelectronic interface comprising:

• a bandpass filter into which the incoming light signals are input and which is arranged to produce filtered light signals, the bandpass filter being configured to let through all the carrier signal wavelengths of the plurality of predefined communication protocols;
• a photoreceptor arranged to produce incoming electrical signals from the filtered light signals;
• and
• a processing unit arranged to acquire the incoming electrical signals, to select a specific software module associated with the specific communication protocol among a plurality of different software modules, each associated with one of the predefined communication protocols, and to interpret the incoming electrical signals using said specific software module.
