This paper colligation analyses the transmission technology of the passive optical network and present that the transmission technology of time division multiplexing for the passive optical network is the main development direction of narrow band service and future broad band service .Simultaneity
this paper also provide adequate discussion to the fundamentdls and characteristics and the key technology of the passive optical network
and simply introduces the narrow band passive optical network flexible access equipment
which is researched in the our institute.
