Recommendation ITU-T G.9807.1 describes a 10-Gigabit-capable symmetric passive optical network (XGS-PON) system in an optical access network for residential, business, mobile backhaul and other applications. This system operates over a point-to-multipoint optical access infrastructure at the nominal data rate of 10 Gbit/s both in the downstream and the upstream directions. XGS-PON systems are able to […]

L’ARCHITECTURE DU G-PON
Le G-PON (Gigabit PON) est la solution qui a été choisie par le Groupe FT pour la solution de déploiement FTTH (Fiber To The Home). Les solutions G-PON déployées offrent un débit de 2,5 Gbit/s dans la voie descendante et 1,25 Gbit/s dans la voie montante. L’infrastructure ODN (Optical Distribution Network) est totalement passive comme […]
Physical layer requirements of FTTH GPON Network
This section describe physical layer requirement for FTTH GPON network in three perspective, 1, Spectral Width,2. Attenuation Range, 3. ODN topology, etc. 1 Spectral width [ITU-T G.984.2] defines certain PMD specifications for the OLT and ONU. For a GPON system operating at 2488 Mbps downstream rate and 1244 Mbps upstream rate, the 20 dB spectral […]
