✦ Synopsis

A regenerative prescaled clock recovery device based on an optoelectronic version of the Miller divider has been tested in high-bit-rate OTDM systems. Tests at 4 = 2.5 and 4 = 10 Gbitrs have been performed to characterize the locking range and the frequency response of the device. The timing jitter of the recovered signal in the case of the 4 = 10 Gbitrs OTDM system does not exceed 0.5 ps. Finally, a comparison of two bit-error-rate measurements Ž . with and without the clock recovery system were carried out for the 4 = 10 Gbitrs OTDM system. The relevant penalty for each channel is negligible, while the maximum received power difference among the four channels at a bit error rate value of 10 y10 is around 0.7 dB.

This paper is concerned with a systematic approach for evaluating the optimal placement of an optical amplifier on a fiber link using a direct detection digital transmission system. The optimum position corresponds to maximizing the signalto-noise ratio at the receiver. The presented theory confirms
