Key Terms

• PON ‐ Passive Optical Network‐ (Carrier) Between Central Office (CO), or substation, and the premises in FTTx.

• POL - Passive Optical Local Area Network

- (Enterprise) Between the data center / equipment room and the user*.

*A user can be a human or device. (Virtually any IP device with an RJ-45 interface)

• GPON - Gigabit Passive Optical Network

A thought to begin with…

“If 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 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

• 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

GPON Evolution

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

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

Evolution 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

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.

Game changer & Disruptive Technology

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

Different PON Technologies ( B‐PON   ‐ G‐PON   ‐ E‐PON )Different PON Technologies ( B‐PON   ‐ G‐PON   ‐ E‐PON )

PON (Passive Optical Network) is a point-to-multipoint network architecture in which unpowered optical splitters are used to enable a single optical fiber to serve multiple premises / users

BPON (Broadband PON) is a standard based on APON

GPON (Gigabit PON) is an evolution of the BPON standard - based on the ITU standard (ITU-G.984)Asymmetrical bandwidth 2.4Gbs / 1.25Gbs

EPON (Ethernet PON) is an IEEE standard and is now part of IEEE 802.3 standard (IEEE 802.3ah)Symmetrical bandwidth 1.25Gbs / 1.25Gbs

Fundamentally GPON and EPON are based on the same technology principles

GPON Details

• Single, singlemode fiber to each work area‐ Downstream up to 2.4Gbs @ 1490nm – (TDM) voice, data, switched video‐ Upstream up to 1.2Gbs @ 1310nm – (TDMA) voice, data, signaling video‐WDM video (RF/Analog) overlay @ 1550nm‐ All simultaneous‐ ITU‐G.984 standard recommendations

• Technically Future Proof (Passive Components)‐ SM fiber has an unknown bandwidth limitation. ‐ Until electronics reach the limit, glass manufacturers will not design  “next generation” singlemode

‐ Upgrades to the next generation are as simple as replacing the electronics

PON Facts and Benefits

• No power required from the data center to the user area

• Multiple buildings served by one main equipment room

• Up to 50% reduction in power consumption

• Significantly reduced cabling construction costs

• Reduced bulk allow for more flexible architectural

design considerations

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

• 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)

• Lower future expansion costs

Splitter Technology

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

• Two types used:• 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

POL vs. Conventional Cabling 

• The POL solution eliminates cable congestion by using small form factor factory terminated multi‐fiber cables and MT connectors 

• The POL solution utilizes a single fiber for all services reducing cable bundles.

• Traditional networks would require a home run from each user for voice, data, and even video.

Standards UpdateStandards Update

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

On August 14, 2012, TR-42 issued an addendum to the TIA-568-C0 Generic Telecommunications Cabling for Customer Premises standard that adds PON technology standards as supported singlemode fiber applications for the LAN.

The TIA TR-42.10 committee plans to have the first iteration of its standard ready for review in early 2013, with the potential for a ballot vote in June

Note: PON added to 14th Edition of TDMM under Horizontal Cabling

“As a standards organization, we are at the forefront of technology, and we realized the PON was one of the latest leading technologies we wanted to embrace,” says Tony Zarafshar, the IT manager for TIA.
