The difference between XG-PON and XGS-PON is:

XG-PON: 10 G GPON Asymmetric mode DS 9.953 Gbit/s - US 2.488 Gbit/s

XGS-PON: 10 G GPON Symmetric mode DS 9.953 Gbit/s - US 9.953 Gbit/s

Xgs-pon is symmetric protocol with 9.953 Gbit/s speed in both directions
Xg-pon is assymetric protocol with lower upload speed (9.953 Gbit/s for downstream and 2.488 Gbit/s for upsteam). This post was last edited by Peterhof at 2018-07-21 09:21.

The difference is the mode (upstream rate):
XG-PON: 10G GPON asymmetric mode (downstream line rate 9.953 Gbit/s, upstream line rate 2.488 Gbit/s)(lower upstream rate)
XGS-PON:10G GPON symmetric mode (downstream and upstream line rates are 9.953 Gbit/s)

The main difference between XG-PON & XGS-PON is the upstream line rate.

XG-PON (10G downstream / 2.5G upstream) – ITU G.987, 2009. XG-PON is essentially a higher bandwidth version of GPON. It has the same capabilities as GPON and can co-exist on the same fiber with GPON. XG-PON has been minimally deployed to date.

XGS-PON (10G downstream / 10G upstream) – ITU G.9807.1, 2016. XGS-PON is a higher bandwidth, symmetric version of GPON. Again, the same capabilities of GPON and can co-exist on the same fiber with GPON. XGS-PON deployments are just beginning.

XG-PON: 9.953 / 2.488 Gbit/s assimetric protocol.
XGS-PON: 9.953 / 9.953 Gbit/s simmetric protocol.

the main difference between the XG-PON and XSG-PON is the upstream, XG-PON runs in asymmetric mode meaning downstream and upstream is not the same, it has 9.953Gbit/s downstream and 2.488Gbit/s, while the XSG-PON uses symmetric mode that have 9.953Gbit/s for both upstream and downstream.
