Abstract :
Demonstrates 140 Mbit/s FSK transmission with a -56.7 dBm receiver sensitivity. The system features endless polarisation control and Manchester coding at the transmitter to overcome the nonuniform FM response of the DFB-laser in conjunction with a highly efficient subcarrier demodulation scheme in the receiver.
