Discrete optoelectronic device for an access or end point of an optical wireless network

An optoelectronic device for an access point or an end point of an optical wireless communication system comprising:

• a transmitting optoelectronic module capable of converting a digital signal into a light signal to be transmitted,
• a receiving optoelectronic module capable of converting a received light signal into a digital signal,
• a control module controlling said transmitting optoelectronic module and receiving optoelectronic module, and
• a power supply module supplying said transmitting optoelectronic module with current selected by said control module, and said receiving optoelectronic module and said control module with voltages selected by said control module,
• wherein said control module comprises i) a transformer ensuring a conversion of an analog signal received in a differential form into a single first intermediate signal, ii) a first group of passive components carrying out a pre-equalization of said first intermediate signal in order to deliver a second intermediate signal, iii) a first amplifier amplifying said second intermediate signal received on a first input in order to deliver a third intermediate signal on an output, and iv) a transistor comprising a gate receiving said third intermediate signal and a drain connected to said transmitting optoelectronic module, the latter being biased by a voltage supplied by said power supply module and defining a mean bias current level and having a current flowing through it with fluctuations between minimum and maximum values induced by fluctuations of said third intermediate signal.
