In this paper, Decision Feedback Equalization (DFE) and Feed forward Equalization (FFE)based on minimum mean square error optimization has been employed to improve the performance of 32 channels, gigabit capacity WDM-PON network. An optical line terminal (OLT) installed at the transmitter end which continuous transmit 32 channels having different colors (wavelengths) of 20GB/s data rate , which is multiplexed by optical multiplexer and transmit through standard single mode fiber (SMF) having length 40km. A link design for 1:64 optical splitters is used as Passive Optical Network (PON) element which creates communication between OLT to different end users. It is observed that FFE and DFE significantly reduce BER by 1.0798e-010, 1.1556e-011, 1.2960e-010 and 8.8979e-009 at four different wavelengths 1550nm, 1559.6nm, 1562.8nm and 1574.8nm by using NRZ (non return zero) modulation format at 20GB/s for 64 users having 40km fiber length respectively. Sharp increase in BER 2.6916e-002, 4.6519e-002, 3.8804e-001 and 5.1570e-002 occurs if data rate increases up to 25 GB/s.
