Abstract :
A circuit for retiming a 1.12 Gbit/s n.r.z. signal in an optical transmission system is described. Retiming in the repeater is accomplished by sampling the n.r.z. signal with a 1.12 GHz clock signal. The resulting r.z. signals are fed to a Schmitt trigger which acts as an RS flip-flop, where the r.z. signals are converted back to n.r.z. signals.
