5. GPON Component
Active Component
 OLT: Central Office Node
 ONT/ONU
 ONT: single integrated unit that terminates PON
network.
 ONU: PON-side half of the ONT, terminating PON
network and may present one or more converged
interfaces such as xDSL or ethernet. ONU typically
require a separate subscriber unit.
Passive Component
 Splitter
 Optical netw. (feeder cable  distribution cable  drop
cable)

6. Sistem GPON
 Berbasis teknologi PON
 1 core  3 λ (full duplex)
