GPON: Gigabit-capable Passive Optical Network
PON is short for Passive Optical Network ;
GPON architecture: Passive optical network featuring one-to-multiple-point;
Optical Line Terminal (OLT)
Optical Network Unit (ONU)
Optical Distribution Network (ODN).
Why GPON?
GPON supports :
Triple-play service: High-bandwidth up to 1.25Gbps/2.5Gbps
Long-reach up to 20km
HDTV: 16-20M/program;
Data: 10M;
Video Conference: 4.5M
GPON is the choice of large carriers in the international market.
GPON Principle—-Data Multiplexing
GPON adopts Wavelength Division Multiplexing (WDM) technology, facilitating bi-direction communication over a single fiber.
To separate upstream/downstream signals of multiple users over a single fiber, GPON adopts two multiplexing mechanisms:
In downstream direction, data packets are transmitted in a broadcast manner;
In upstream direction, data packets are transmitted in a TDMA manner
GPON Principle—-Downstream
Broadcast mode
GPON Principle—-Upstream
TDMA (Time Division Multiplex Access) mode
