Abstract:

In order to solve the problem in choosing wining structure of building the FTTH (Fiber To The Home)network under the uncertain conditions of access users,we use qualitative and quantitative analysis methods to compare  cross-connecting distribution line type of ODN(Optical Distribution Network) structure and direct connecting distribution line type of ODN structure,find out that  it has a stable access ability and a wide covering ability and a flexible expansion ability,so that is appropriate for the application in the competitive telecommunication market，has certain reference significance during large-scale construction projects on the FTTH network.

Key words: optical access network (OAN), fiber to the home (FTTH), optical distribution network (ODN), direct connecting distribution line, cross-connecting distribution line
