Different combined modulation modes of DPSK and OOK are separately employed for the upstream and downstream links.By comparison with different modulation formats in the downstream link
20 km upstream and downstream transmission at a symmetric rate of 10 Gbit/s is realized without dispersion compensation
which shows that higher extinction ratio in the downstream link and better dispersion tolerance in the upstream link can be realized by employing the combined modulation with IRZ code so as to enhance the overall performances of the transmission system.
