What are the Differences between GPON XG-PON and XGS-PON?
With the development of telecommunication technology and times, G-PON speed cannot meet the needs of home and enterprise users, so PON began to evolve to a 10Gbps level.
What is a PON Network?
PON (Passive Optical Network) consists of OLT, ODN, and ONU. As an important node for service aggregation and distribution, the OLT device is located at the core of the network topology and connects to multiple service networks upwards and users’ services downwards through the ODN. PON is the main technology to realize FTTH fiber access.
How Many Main Types of the PON?
PON technologies can be divided into 2 categories.
Mainstream PON: GPON and EPON are the two most widely used PON technologies..
The difference between EPON and GPON
GPON originated from ATM PON technical standard and has formed the latest generation of integrated broadband passive optical access standards based on the ITU-TG.984.X standard.
EPON is based on IEEE standard which adopts a point-to-multipoint structure and passive optical fiber transmission mode to provide a variety of services on Ethernet.
10G-PON( Next Generation-PON ): Including 10G-EPON, XGPON, XGSPON.
According to the differences, we can divide it into 10/1G-EPON、10/10G-EPON、XG-PON(10/2.5G-GPON)、XGS-PON(10/10G-GPON).
The upstream and downstream bandwidths are the same, which we called symmetric PON. The upstream and downstream bandwidths different are called asymmetric PON.
What is the Main Different between Them?
From the chart, we can know that the biggest difference between GPON, XG-PON, and XGS-PON is the transmission rate.
- The G-PON maximum downstream line-rate transmission is 2.5 Gbit/s, and the maximum upstream line rate is 1.25 Gbit/s
- The XG-PON maximum downstream line-rate transmission is 10 Gbit/s, and the maximum upstream line rate is 2.5 Gbit/s
- The XGS-PON maximum downstream line-rate transmission is 10 Gbit/s, and the maximum upstream line rate is 10 Gbit/s
