Abstract :
The feasibility of polarisation insensitive multichannel coherent FSK transmission with synchronous intra-bit sinusoidal polarisation spreading has been experimentally demonstrated at 622 Mbit/s for the first time, complying with a front-end bandwidth of 3.2 GHz. Results evidenced an optimum IF filter bandwidth of four times the bit rate, and a minimum channel spacing of 11 GHz.
