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
PON Facts and Benefits
Active Components – Located in the MDF
• Optical Line Terminal – OLT –‐ Located in the Data Center‐ After the Level‐3 WAN router‐ Uses GPON protocols‐ Support VLAN (over 4500)‐ 128‐bit security encryption
Different vendors provide OLT solutions based on same ITU984 standard
Active Components – Located at the desktop area
• ONT – Optical Network Terminal
‐ Located near the user or device
‐ 4 RJ45 (10/100/1000) output ports with optional POE
‐ Up to 62W* of available POE
‐ Standard HVAC is adequate
‐ Optional internal or external battery back‐up.
‐ Up to 8 VLAN per port and a max of 16 VLAN per ONT*
*Vendor SpecificONT – Optical Network Terminal
Different vendors provide ONT devises from desk-top to wall-mount - proprietary solution –

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.
