FTTH ODN
Solution Overview
FTTx (Fiber To The X) is a new generation of fiber access network that connects telecom operators and end users, employing active or passive optical network. Most of current FTTx applications, FTTH (Fiber To The Home), for example, feature passive optical network. A FTTH network architecture mainly consists of OLT (Optical Line Terminal, terminal equipment is used to connect fiber trunks), ODN (Optical Distribution Network, including fiber and passive splitter or coupler), and ONT (Optical Network Terminals, a type of ONU).
How does it work?
The common types of FTTH fiber access technologies are P2P (Point-to-Point Network), PON (Passive Optical Network, point-to-multipoint structure), and P2MP (Point-to-Multipoint PON). P2P technology has been adopted by large enterprises and key institutions, featuring high bandwidth, simple network structure, and low operation and maintenance costs; P2MP is the mainstream technology designed for general residential subscribers, which enables the shared fiber connection, and thus contributes to less fiber cost and high bandwidth. A typical ODN solution contains fibers, and cross-connecting and splitting devices such as Optical Distribution Frame (ODF), Fiber Distribution Terminal (FDT), Splitting and Splicing Closure (SSC) and Fiber Access Terminal (FAT).
