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 ). [boxads] Specification Differences Between 10G GPON and GPON The following table lists specification differences between the two technologies. Specifications GPON 10G GPON XG-PON XGS-PON Wavelength Downstream: 1480-1500 nm Upstream: 1290-1330 nm Downstream: 1575-1580 nm Upstream: 1260-1280 nm Downstream: 1575-1580 nm Upstream: 1260-1280 nm Center wavelength Downstream: …
