Abstract

Optical cross-connects (OXC) introduce crosstalk and intersymbolic interference due to filtering in the optical signal. We show experimentally and by simulation that higher optical signal-to-noise ratio (OSNR) penalties are obtained for the combined effect of both impairments compared to the sum of the penalties taken independently. Furthermore, the Modified Chernoff Bound is applied for performance estimation, with good accuracy and fast computation time. By using the correct OSNR penalty, the maximum number of cascaded OXC is reduced by 17% relatively to when the penalties are considered separately, for a 2 dB maximum penalty.
