A communication link for communicating data between a first opto-electronic equipment capable of providing an optical signal and a second opto-electronic equipment capable of receiving the optical signal is described. The communication link comprises includes a first optical channel and a second channel. The first optical channel is preferably a high-speed optical channel for conveying information requiring high-speed connection and the second channel is preferably a slow channel providing, for example a low-power monitoring function. An opto-mechanical device for providing a communication link, comprising including a first opto-electronic equipment for providing an optical signal, a second opto-electronic equipment for receiving the optical signal, a first optical channel and a second channel is also described.
