Switched optical transmission: exploration of trade-offs between packaging options

Abstract

This paper presents an approach to switched electrical and optical transmissions using a pseudo-optical switching system. Packaging alternatives for the switching matrix are explored for OC-3 and OC-12 norms, with the aim of achieving a low system noise. The characteristics of a prototype pseudo-optical switch composed of transimpedance and differential amplifiers, multiplexers and GaAs laser drivers are also presented.
