Paper Abstract

A reconfigurable tri-directional transmission module (TTM) is proposed and experimentally demonstrated in a dense wavelength division multiplexing (DWDM), 2.5 Gb/s x 100 Km lightwave system. Channel spacing is 100 GHz (0.8 nm) in our study. Bit error rate floor of 10-4 exists due to channel crosstalk and Rayleigh back scattering is observed. Nevertheless, power penalty could be effectively reduced to 0.6 dB by using a tunable bandpass filter. This module may find an important role in the tri-directional lightwave system, especially when wavelengths interchange, optical cross connect and optical add/drop functions are necessary.
