1. In a first multi-channel optoelectronic device, a method of establishing a redundant status link with a second multi-channel optoelectronic device, the method comprising:

  • generating a status link modulation signal from status data, the status link modulation signal comprising a low frequency modulation current and representative of the status data;

    effectively applying the status link modulation signal to at least two transmitter bias currents to generate at least two status-link modulated transmitter bias currents;

    modulating each status-link modulated transmitter bias current with a different primary data modulation signal to obtain at least two resulting signals, wherein each primary data modulation signal comprises a high frequency modulation current and represents a different primary data electrical signal received by the optoelectronic device;

    providing each resulting signal to a different optical transmitter for transformation into at least two optical signals; and

    transmitting the at least two optical signals over a multi-channel communication link to the second multi-channel optoelectronic device.
