Along with the further development of fiber-optic access
it will be an inevitable trend for xDSL to evolve into FTTx and fiber access networks will become the main carriers between MAN/SS and home gateway/IAD.As a new generation optical network access technology
EPON access is one of the key techniques for realizing FTTx.This paper briefly discusses the EPON network system and its work principle
with the focus on the way of implementation of EPON technology in carrier networks
and points out the problems in this process.Finally
it predicts the prospects of the development of EPON technology.
