PON Technologie (Passive optical network)

FTTx Solution Overview


• PONs provide cost-effective access systems because the transmission fiber and the central office equipment can be shared by several customers.

• PON systems are popular as major FTTx systems around the world.

PON Background


PON introduction

PON High capacity and efficient use of bandwidth allows many applications and flexible network configurations


PON Fundamentals


PON architecture

All optical network architectureVery high speed

All passiveBrings homes/premises broadband services


Fiber Access Network Architectures

Basically, there are 3 Architectures for Fiber- deployment

P2P (point to point)

P2MP (point to multi point)

Active Star ( combination with copper )


Network Topologie 1/2

P2P Ethernet network topology using fiber pairs

Source: EXFO

+ Future proof architecture+ Unlimited bandwidth+ Lowest equip cost

- Cost of fiber plant- Fiber management at CO


Network Topologie 2/2

Passive P2MP PON topology using single fibers and splitters

Splitter / Coupler

Operating wavelenght ranges

In accordance to the ITU-T G.938.1 recommendation , every splitter used in FTTH

application has to work at least at 3 wavelenghts :

1310nm ( data / voice upstream )

1490nm ( data / voice downstream)

1550nm ( video signal )


Different choices for Splitter architectures

The two common splitter configurations are the cascaded and the centralized

approaches

When splitters are cascaded together, loss will occur at each device.The combined loss effect can reduce the distance.

The centralized splitter minimizes that signal loss by eliminating extra splices and/or connectors from the distribution network.
