Abstract

Performances of a WDM multistage interconnection architecture have been evaluated, by using measurements carried out on a 8×8 MEMS 2-D photonic switch made by OMM Inc.. Maximum and minimum insertion losses resulted 3.96 dB and 1.42 dB respectively at the wavelength of 1540.5 nm. Furthermore polarization dependent loss and crosstalk were below 0.7 dB and -79 dB respectively. A rise time of 12 ms and a fall time of 4 ms were measured. The measurements were used to study a 40 Gbit/s WDM network which operates by using two fibers each supporting 8 multiplexed channels for a total of 16 channels whose carriers are spaced by 50 GHz and modulated at 2.5 Gbit/s. The network includes an optical cross connect (OXC), designed to switch part or all of the eight channels from one fiber to another. The heart of the OXC is a 16×16 strictly non-blocking switching matrix based on a three stage Clos architecture. Insertion losses lower than 7 dB were evaluated over the entire network and the eye diagram spreads by just about 4%.
