Software-Decision FEC11.3dB more net coding gainBER from 2.4e-2 to 1e-15Support 100G@1500km optical transmission system

Electronic Mitigation to nonlinear impairments (using DSP) Enable the 100G system to work with high launch power and extend the reach.Enable 100G work with 10G and 40G, to reuse the existing equipment

Electronic Mitigation to WSS filtering impairments (using DSP)For WSS in which CD (ripple) is dominant, hybrid equalization can provide great compensation performance.
