Adaptive modulation is the technology that allows the system to adaptively change the optical signal parameters (the modulation level, the symbol rate, the number of subcarriers and the carrier frequency) according to the latest conditions of the optical distribution network
A typical optical distribution network
usually has a star topology with a single branching point, or a tree topology with several branching points , which makes the methods for OLT backup difficult.
An AGILE model, OPHL, represents a dual case of the optical distribution network
in the electrical domain.
At the end of optical distribution network
there is a 1x16 AWG demultiplexer where optical signal is split into 16 optical streams (wavelengths) and sent to receiver section.
The company has developed over 60 Intelligent Optical Distribution Networks
In October 2010, Huawei launched the industry's first Intelligent Optical Distribution Network
(iODN) solution and was recognized with a Broadband InfoVision Award at the Broadband World Forum (BBWF).
ZTE will offer comprehensive services to China Telecom to support the growth of next-generation PON technology and intelligent optical distribution network
(ODN), helping China Telecom build superior network infrastructure.
Huawei, a leading global information and communications technology (ICT) solutions provider, announced that its proposal for intelligent optical distribution network
(iODN) standards has been adopted by the Broadband Forum (BBF) at its 2012 3rd quarter conference, representing a breakthrough for international standards in the field of ODN.
