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 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
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 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. Taking unnecessary intelligence and functionality away from the edge in order to create a more efficient architecture
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 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.
Lower future expansion costs PON Facts and Benefits 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)

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 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 14 th Edition of TDMM under Horizontal Cabling

Case Study: TIA Headquarter USA 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.
