Two optical crosstalk mechanisms, homo- and hetero-wavelength crosstalk, are identified in multi-wavelength switched networks. Homo-wavelength crosstalk does not arise in point-point systems and is a significant factor in multi-wavelength network design. A new signal dependent statistical model was used to evaluate the crosstalk effects due to non-ideal filtering in an established multi-wavelength transport network architecture. The authors find that the optical filters used in this network must have an adjacent channel rejection of /spl ges/20 dB in order to achieve the system design target of 622 Mbit/s channel base rate, at 10/sup /spl minus/10/ BER with 1 dB crosstalk penalty through 10 nodes. >
