        abstract = {In this paper, we investigate effects of Erbium-doped fiber amplifier (EDFA) amplified 
spontaneous emission (ASE) noise on the performance of multi-wavelength OCDMA-based Long-
Reach Passive Optical Networks. In addition, other  noise and interference such as shot noise, 
thermal noise, beat noise, and multiple-access interference (MAI) are included in our theoretical 
analysis and simulation. We found that the location of EDFA on the link between OLT and ONUs 
plays an important role in network design since it affects network performance. Analytical results 
show that, to achieve low bit error rate, the EDFA  should be located around 10 to 20 km from 
OLT when total link distance of 90 km.}
