• PON is Passive Optical Network with Point-to-Mulitpoints (P2MP) topology.• PON consisted of Optical Line Terminal (OLT), Optical Network Unit (ONU)and Passive Optical Splitter (POS).

PON Transmission Principle
TDM deployed by downlinkTDM (Time Division Multiplexing )
TDMA deployed by uplinkTDMA (Time Division Multiple Access )
• Downlink wavelength is 1490nm;• Hybrid data transmitted from OLT to customer ONU through splitter;• Everyone ONU only receives data to itself and drops others.
• Uplink wavelength is 1310nm;• Everyone ONU send data to OLT within OLT permitted time slot;• No collision detection is needed;• No fragment is needed for frames.

EPON Technology Advantage
• High bandwidth Up to 1000Mbps, by deploying Point-to-multipoints fiber access technology.• Cost effective Uplink traffic from ONU to OLT is aggregated by splitters, which takes the place of co
nvergence switches. Hence, network construction cost was reduced, network layers was simplified and network O&M cost was saved.
• Saving in fiber resources By deploying EPON technology, backbone fiber resources was greatly saved, as well
as uplink optical interface and optical modules.• Dynamic bandwidth allocation (DBA) ISP could configure 1Mbps – 1Gbps bandwidth dynamically according to customer re
quirements.• Easy management and maintenance Different from convergence switches, splitter is passive and anti-thunder and needs n
o device management and equipment house. • Flexible topology, wide coverage According to application, EPON could be constructed as tree, star or bus topology, w
hich covers 10-20km.
