What is GPON (GPON Networks)?
Part 1. Introduction
Passive Optical Network (PON) is a system that delivers fiber optical cabling and signals to the home or business (FTTx) with a point-to-multipoint architecture. It allows access to video, voice, and data. There are many different standards of PON and GPON is one of them. It is first put forward by FSAN and completed in 2004.
Main Features:① The upstream and downstream speed is 1.2 Gbps and 2.4 Gbps.
② It protects users' data secure and private via encryption.
③ Triple-play services: VoIP, Data and IPTV
④ Long-reach coverage is up to 20km.
Part 2. How GPON works?
GPON FTTH access network is composed of an optical line terminal (OLT), optical splitter and optical network terminal (ONT). GPON can transmit ethernet, TDM (Time Division Multiplexing) and ATM traffic.
The OLT is responsible for converting the optical signals to electrical signals and presents them to a core Ethernet switch. The optical splitter is used to split the power of the signal. ONT is deployed at the customer's premises. It will receive the signal sent from the optical splitter or will send the signals back to the OLT.
Part 3. Why Choose GPON?
GPON is a point-to-multipoint system instead of a point-to-point one, which is superior to the point-to-point Ethernet connections. This advantage reduces the cost. With the development of technology, FTTx is the best choice that can meet users' needs. Compared with copper, there is less interference and safer. As for the difference between GPON and EPON, GPON is a better choice for those who care more about bandwidth, QoS, and security.
