In one embodiment, an apparatus includes a processor, a laser, and a modulator. The processor is to generate a first electrical signal including first data and a second electrical signal including second data. The laser is to generate a multiplexed carrier signal comprising a first carrier signal and a second carrier signal, the laser to operate at a first laser power setting. The modulator is to generate a multiplexed optical signal including a first optical signal based in part on the first electrical signal and the first carrier signal and a second optical signal based in part on the second electrical signal and the second carrier signal. The apparatus is to transmit the multiplexed optical signal to a device and to retransmit the first data from the apparatus to the device based on a detection of error in a received version of the first data at the device. Other embodiments are described and claimed.
