Investigation on adaptive equalization techniques for 10G-glass optics based 100G-PON system

Requirements on adaptive equalization of 25Gb/s NRZ transmission system for 10G-class optics based NG-EPON are analysed with FFE, DFE and MLSE. Experimental results show that combination of FFE and DFE can achieve similar performance in B2B case and about 1.2 dB decline for 25-km transmission case compared to MLSE.
