Conclusions In this paper we showed for the first time, the assessment of the MB 1 × 2 WSS operating with higher order modulation formats. We have shown the device operating with 33.3 GBd 64-QAM resulting in a net data-rate of 169.83 Gb/s with a limited OSNR penalty across all tested channels and bands. We have also shown that the passband shape of the WSS had to be modelled according to a two Gaussian sum for matching the experimental results. With this we investigated the filtering and capacity reduction effect on the MB OADM node due to the cascading of multiple WSS, showing that for the case of this device the bandwidth was only 20% of its original value after 20 traversed nodes, which in turn highlights the importance of keeping the number of transparently traversed nodes small or adjusting the spectral response of new photonic integrated WSSs to a flat-top one. 5.

N2 - PIC multi-band WSS is evaluated with 33.3 GBd 64-QAM data. BER values below the FEC-limit for the S, C and L-bands are obtained. The 3dB bandwidth scaling of cascading WSSs is also investigated for a metro-access network.
