Part 1. What Is GPON (GPON Networks)?
The meaning of GPON is Gigabit Passive Ethernet Network. Passive Optical Network (PON) is a system that delivers fiber optical cabling signals to the home or business (FTTx) with a point-to-multipoint architecture.
It allows users to access video, audio, Internet data, etc. There are plenty of different standards of PON and GPON is exactly one of them. It was first put forward by FSAN and completed in 2004.
Main Features of GPON include:
① The upstream and downstream speeds are 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 Does GPON Work?
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 Networks?
GPON is a point-to-multipoint technology instead of a point-to-point one, which is superior to point-to-point Ethernet connections.
This characteristic 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.
Part 4. Application of GPON
By the demand of FTTx and the GPON network standard, VSOL has developed a series of GPON routers including GPON ONU/ONT and GPON OLT. There are several types of GPON devices for different needs and scenarios to provide services such as WiFi, CATV, VOIP, etc.
