Multi Gbit/s bit parallel WDM transmission using dispersion managed fibers

This paper demonstrates the feasibility of a bit parallel WDM (BP-WDM) syst em using dispersion managed fibers. An expression for the total bit skew as a function of the fiber dispersion and system bandwidth is derived and com pared with experimental results. A 4 bit x 10 Gbit/s-per bit BP-WDM transmi ssion experiment over 30 km DMF is used and an aggregate bite rate x distan ce product of 1.2 Tbit/s-km is obtained. The total bit skew of the system i s reduced to one half of the bit period. We believe that systems using BPWD M will be useful for computer interconnects in high-speed parallel systems and ring networks.
