Abstract

As the single-channel bit rate will increase towards 160 Gb/s in future photonic networks, the effects of timing jitter on transmission performance becomes severe [1]. It is therefore essential for 3R regenerators to be able to significantly reduce the jitter of the degraded incoming data signal and thereby perform retiming. Several methods for 3R regeneration have been investigated, see [1]; however, little attention has been given to retiming. In this paper, based on a newly developed numerical model, we investigate the jitter (retiming) transfer function of the 3R regenerator in the presence of the recovered clock signal. The effects of data signal jitter and pulse shape, recovered clock signal jitter and FWHM of control signal pulses on the timing jitter of the retimed data signal is investigated.
