FTTH/FTTB GPON Architecture

Advantages

Lower costs for investments in Infrastructure due to passive splitters

Disadvantages

Optical fibre architecture can be used with PON only

Later decision towards Point-to-point leads to further investments

GPON Advantages

Shared infrastructure translates to lower cost per customer

Minimal number of optical transceivers

Feeder fiber and transceiver costs divided by n customers

Passive splitters translate to lower cost

Can be installed anywhere

No power needed

Essentially unlimited MTBF

Fiber data-rates can be upgraded as technology improves

now 1.25Gbps, 2.5Gbps

soon 10Gbps

20 km reach in case of 28 dB optical budget

GPON Advantages

High performance despite shared medium

DBA: Dynamic Bandwitdh Allocation

Rate limiting as demanded from the customer product

GPON Encapsulation (GEM) supports multiple data types

simultaneously

Ethernet: natively supported

TDM: natively supported or through circuit emulation service

(CES) over IP / Ethernet

ATM: natively supported, but unfavorable, as operators convert

to Ethernet-/IP-Netze

ONT Management and Control Interface (OMCI)

93% bandwidth efficiency

As per standard, up to 8 classes of service

Overview ONT Activation

ONT Discovery

OLT recognizes arrival of an ONT

OLT discovers the Serial Number

OLT assigns ONT_id to ONT

ONU ID: between 0…253 for ONU (254 for broadcast)

ONT Ranging

OLT measures arrival phase

OLT provides equalization delay

ONT adjusts TX phase

Services can be provisioned

© KEYMILE


ONT Ranging

Upstream traffic is TDMA (time division multiple access)

Were all ONUs equidistant, and were all to have a common

clock

then each would simply transmit in its assigned timeslot

But otherwise the signals will overlap

To eliminate overlap

guard times left between timeslots

each ONU transmits with the proper delay to avoid overlap

delay computed during a ranging process
