GPON, XG-PON, XGS-PON, What is the difference?
- XG-PON, 10-Gigabit-capable passive optical network, provides asymmetric 10G GPON transmission (Maximum downstream line rate: 9.953 Gbit/s, Maximum upstream line rate: 2.488 Gbit/s ).
- XGS-PON, 10-Gigabit-capable symmetric passive optical network, provides symmetric 10G GPON transmission (Maximum downstream line rate: 9.953 Gbit/s, Maximum upstream line rate: 9.953 Gbit/s ).
