Abstract : In optical time division multiplexed (OTDM) optical
data streams are constructed time multiplexing a number of lower
bit rate optical streams. The advances in OTDM systems and
components research show the technique to be highly suited to the
generation and transmission of high capacity data on a single
optical carrier. In this work, Spectrum compression based on
filters for improving bandwidth efficiency is presented and
demonstrated experimentally in 40 GB/s OTDM system. Even
after 100km transmission, de multiplexing and clock recovery can
be implemented successfully, and the data rate-to-bandwidth
ratio has been improved.
