Luego de leer un poco hay que aclarar que:
GPON provides 2.5 Gb/s downstream and 1.2 Gb/s upstream, shared among 32 endpoints (currently; the technology is supposed to evolve to support 64 endpoints). In other words, each endpoint gets around 80 Mb/s downstream and around 40 Mb/s upstream. 2.5 Gb/s is the downstream system capacity between the optical line terminal and optical network terminal, not the service offered to an individual customer. In addition, the back end of the optical line terminal is typically a single GbE port into the carrier»s backbone, so there»s a contention factor which limits the total bandwidth available to the subscribers served by the OLT to less than 1 Gb/s.
Traducción rápida de la idea general:
PON provee 2.5 Gb/s de bajada y 1.2 Gb/s de subida compartido con 32 puntos finales (usuarios). Osea que cada punto tendrá alrededor de 80 MB/s de bajada y 40 MB/s. Los 2.5 Gb/s es la capacidad de bajada entre la linea terminal óptica y la red, no al usuario final.
De todos modos 80 MB/s es mucho.
