Abstract

We study the transmission performance of Manchester encoded signals over multimode fibers at 1.25 Gb/s and 2.5 Gb/s focusing on regimes where there is strong slowly time varying signal fading and noise corruption. This fading and noise is due both to the modal noise and the dispersion varying cruel environmental effects. A non-return-to-zero (NRZ) modulation scheme typically used in the transmission suffers severally from such slowly varying signal fading; whereas Manchester encoded signal, which carries the binary value by the pulse position within a bit slot, in contrast, has a better performance in coping with the slowly varying signal degradation. In this paper, we study the transmission performance of these two signaling schemes, and the results show that Manchester encoding outperforms NRZ in coping with slowly varying signal degradation.
