China’s three operators have already released the 1000Mbit/s plan and broadband access users with a rate of 1000M or above are over 45.96 million in the first quarter of 2022 according to the statistics of the Ministry of Industry and Information Technology of China.
In Addition, many ISPs of foresight deployed XGPON ONT for the high valued sites or began to purchase 10G GPON ONT for testing in order to take the lead in the fierce market from last year.
Isn’t it a necessity to know more knowledge about 10G GPON and 10G GPON ONT?
Evolution from PON to 10G PON
PON terminals are greatly faster than xDSL/LAN terminals, which are the mainstream choice for home users now. However, EPON and GPON technologies cannot provide sufficient bandwidth for increasingly bandwidth-intensive services. To address the preceding issues, 10G PON technology is introduced.
10G PON can be classified into 10G EPON and 10G GPON, which evolved from existing EPON and GPON technologies respectively. And 10G GPON technologies include XG-PON and XGS-PON.
The following table lists the differences between GPON and 10G GPON(XG-PON and XGS-PON):
|Wavelength||Downstream: 1480-1500 nm||Downstream: 1575-1580 nm||Downstream: 1575-1580 nm|
|Upstream: 1290-1330 nm||Upstream: 1260-1280 nm||Upstream: 1260-1280 nm|
|Center wavelength||Downstream: 1490 nm||Downstream: 1577 nm||Downstream: 1577 nm|
|Upstream: 1310 nm||Upstream: 1270 nm||Upstream: 1270 nm|
|Maximum Line Rate||Downstream: 2.488 Gbit/s||Downstream: 9.953 Gbit/s||Downstream: 9.953 Gbit/s|
|Upstream: 1.244 Gbit/s||Upstream: 2.488 Gbit/s||Upstream: 9.953 Gbit/s|
|Maximum Physical Transmission Distance||60 km||100 km||100 km|

GPON ONT V.S. 10G PON ONT
The user-side rate of a 10G PON ONT can reach up to 1000 Mbit/s, meeting the requirements of home users on bandwidth-hungry services such as 4K/8K HD video, AR/VR, home cloud, and video calls. It can also provide private line access services of up to 10 Gbit/s.
To make it simple, we will take the most common GPON ONT EG8145V5 and 10G GPON ONT HN8346V5 as a comparison:
|Type||GPON ONT||10G GPON ONT(XGPON)|
2.4G/5G WIFI (5dBi)
2.4G/5G Wi-Fi (5dBi)
|Maximum Line Rate||· Downstream: 2.488 Gbit/s
· Upstream: 1.244 Gbit/s
|· Downstream: 10Gbps
· Upstream: 2.5Gbps
|Wavelength||US 1310nm, DS 1490nm||US 1260-1280nm，DS 1575-1580nm|
|Receiver sensitivity||Class B+
-27dBm ~ -29dBm
For your options, the following table lists the mainstream and hot-selling Huawei 10G PON ONT:
Mainstream Huawei 10G PON ONT
HN8346V5 with XG-PON ONT, 4GE+1POT+2USB+2.4G/5G Wi-Fi 5
HN8546X6 with XG-PON ONT, 4GE+2USB+1POT, 2.4G&5G Wi-Fi 6
HN8546Q with XG-PON ONT, 4GE+1POTS+2USB+2.4G&5G Wi-Fi
HN8145V with XG-PON ONT, 4*GE+1*POTS+1*USB+2.4G/5G WIFI
For example, HN8346V5 is the hot-selling and cost-efficient Huawei Wi-Fi 5 XGPON ONT model, quite suitable for 10G GPON deployment while HN8546X6 is the best option as Wi-Fi 6 and XGPON ONT used for high bandwidth users.
Due to XGS-PON is not fully commercialized, XGS-PON ONT can not be bulk supplied in the market for the moment, thus XG-PON ONT will dominate the market. And please be aware that the premise of deploying 10G GPON is the application of 10G GPON OLT and 10G GPON Service Board.
