CROSSCONNECT SWITCH WITH LARGE ARRAY SIZE AND HIGH BITRATE USING WIDEBAND SWITCH TECHNOLOGY

摘要

This invention provides a permutation switch array using analog pasthrough elements. Incoming optical signals are transferred to the microwave domain, and the permutation switch array provides the necessary switching functions. After switching has been achieved, the switched signals are then reconverted to the optical domain. In a preferred embodiment, the permutation switching array is an NxN array. Coupled to the input and the output of the permutation switching array are 1xN digital switches that perform error correcting functions.
