10G GPON Definition

First of all, what is 10G GPON?

10G GPON is evolved from the existing GPON technology, the factors promoting the technology evolution to 10G GPON are as follows:

• Developing services require higher bandwidths and the GPON technology cannot meet bandwidth requirements.
• Innovative access technologies on the user side require higher bandwidths and the GPON technology will face bandwidth bottlenecks.
• A greater split ratio and a longer transmission distance increase network construction investments.
• XG-PON, provides asymmetric 10G GPON transmission (Maximum downstream line rate: 9.953 Gbit/s, Maximum upstream line rate: 2.488 Gbit/s ).
• XGS-PON, provides symmetric 10G GPON transmission (Maximum downstream line rate: 9.953 Gbit/s, Maximum upstream line rate: 9.953 Gbit/s ).

Most subscribers is data consumer not producer, so asymmetric is more widely applied than symmetric.

Specification Differences Between 10G GPON and GPON

The following table lists specification differences between the two technologies.

From the table we can see,

1, GPON and 10G GPON can not co-working in the same ODN, cause their different wavelength range; Unless use WDM1r

2, XG PON, which been knowns as asymmetric 10G GPON; XGS PON been know as symmetric 10G GPON, have same frame structure

H901XGHD, 10G GPON board for Huawei MA5800 series, precisely it called XG-PON board; The XGS-PON board for Huawei MA5800 series, is H901XSED, H901TWED.
