PON Evolution

Key Terms

• PON - Passive Optical Network• POL - Passive Optical Local Area Network PON Passive Optical Network- (Carrier) Between Central Office (CO), or substation, and the premises in FTTx.- (Enterprise) Between the data center / equipment room and the user*.

Fiber to the Office

Campus MDF

Overarching technology

PON / POL are a point-to-multipoint network architecture in which unpowered optical splitters are used to enable a single optical fiber to serve multipleoptical splitters are used to enable a single optical fiber to serve multiple premises / users

GPON (Gigabit PON) is an evolution of the APON and then BPON standard –GPON= ITU standard (ITU-G.984)Asymmetrical bandwidth 2.4Gbs / 1.25Gbs

Fundamentally GPON is the common demoninator for PON and POL

A thought to begin with…

“If you always do what youIf you always do what you always did, you will always get what you always got.”

Keeping pace with the many changes in ITKeeping pace with the many changes in IT

Change has been to main driver for most enterprises in the last decade

Bandwidth requirements have increased by order of magnitude

Numbers and type of devices connected has also jumped dramatically

Traffic patterns have shifted to more centralised and cloud based

Ironically It’s all happened in an economic environmentIronically It s all happened in an economic environment that gives IT much less to spend.

And yet costly work groups switch based architecture are built the same way

Main Factors for Change

• Rethinking of the physical infrastructure / abandoning old assumptions

• Re-evaluation of the way the LAN architecture is deployed

• Re-consideration of processes and vendors

Ali t f IT t th b i d• Alignment of IT to the business agenda

Gradually an increasing number of enterprises are abandoning some of the assumption they used to make and start looking at alternatives

Game changer & Disruptive Technology

IT architectures are changing and therefore the network architecture has to adapt with it.

Evolution of network technologies departmental and distributed services vs to centralisedEvolution of network technologies…departmental and distributed services vs. to centralised resources into the Data Center or even into the cloud

Emerging trend where intelligence and functionality features are centralised back to a single location or aggregation gg g

Think of Wireless LAN…. Where a relative number of non-intelligent access points feed-up into centralised controllers that provide all the intelligence and functionality for the whole wireless LAN

Now think of GPON as the other disruptive technology where again we are using passive technology down to the desktop and then centralise a lot of the intelligence at the aggregation or core layer within that architecture.

Taking unnecessary intelligence and functionality away from the edgein order to create a more efficient architecture

POL Market DriversPOL Market Drivers

• Functionality– Understand business requirementsUnderstand business requirements

– Rethink and revaluate old assumptions

• Financial– Reconsider procurement

– What business problem does it solve?

• Operational– Improve efficiency / increase security / reduce OPEX

GPON Evolution

The success of the OSP system has created an opportunity to bring the same system design into the enterprise LAN

POL Facts and Benefits

• No power required from the data center to the user areap q

• Multiple buildings served by one main equipment room

• Up to 50% reduction in power consumption

• Multiple buildings served by one main equipment room

• Significantly reduced cabling construction costs

• Reduced bulk allow for more flexible architectural design considerations

• Uses a single strand of single-mode graded fiber.

POL Facts and Benefits

• Lower future expansion costs

• Technically Future Proof (Passive Components)

- SM fiber has an unknown bandwidth limitation.

- Upgrades to the next generation are as simple as replacing the electronics (More on that later)

Splitter Technology

• Splitters are passive components representing an important role in Passive Optical Networks

• Two types used:• Fused Biconilcal Taper (FBT) old technology• Fused Biconilcal Taper (FBT) – old technology• Planar Lightwave Circuit (PLC) – latest technology

• Multiple input (M) and multiple output (N) – 1x2 / 1x8 / 1x16 / 1x32 / 2x32

• PLC Splitter, based on silica optical waveguide technology and precision aligning process

• Theoretical loss for a 1x32 is 15db – good PLC splitter provide <16.5db

Optical LAN Link Budgets

• The maximum PON distance is limited primarily by optical attenuation. Contributors are fiber lossattenuation and PON splitter attenuation.

• Optical LAN loss budges must be between 8dB and 28dB; meaning smaller split ratios mayrequire an inline attenuator to insert more loss.

HalfPower

Attenuator Loss Unit

Optical Loss 1310 nm 0.35 dB / Km


PONSplitter

Fiber loss per km is 0.35 dB (1260 - 1360 nm)


Splice Loss per unit 0.05 dB

Connector Loss 0.35 dB

1X32 PON Splitter 16.7 dB

1:2 split ratio

Every time the signal is split two ways, halfthe power goes one way and half goes theother. So each direction gets half thepower, or the signal is reduced by

10log(0.5)=3 dB

HalfPower




GPON Optical Budget –g( )

Practical loss is 3.5 dB nominal, so everytwo-way split costs about 10 km distance@ 1310 nm

g• Splitter (1:32) = 16.5 dB• Fiber loss (20km) = 7.0 dB•Connector / Splice loss = 3.5 dB

Fiber Deployment Strategies

• Choose Fast & Easy (reduce installation time)

• Flexibility of deployment (knowing exact distance not a key factor)

E t l k d t ff t f• Extra slack does not affect performance (fiber has low loss per km)

• Pre-Terminated cable assemblies: pre-tested at the factory(save time on installation and testing)

• 25-year warranty certifications

Standard Bodies UpdateStandard Bodies Update

In February 2009, the Telecommunications Industry Association TR-42 Engineering Committee published TIA 568 C 1 which was the first revision toEngineering Committee published TIA-568-C.1, which was the first revision to recognize duplex single-mode fiber for use in the horizontal.

On August 14, 2012, TR-42 issued an addendum to the TIA-568-C.0 Generic gTelecommunications Cabling for Customer Premises standard that adds POL technology standards as supported single-mode fiber applications for the LAN.

Note: POL added to 13th Edition of TDMM – Chapter 5 Horizontal Cabling
