Why is 10G needed? More 1Gig Connections 1G has begun replacing 100M Potential bandwidth bottlenecks # of Gig connections in a LAN Between aggregation switches/routers At the datacenter From switch/router to Server From Server to Server

10G Aggregation Application Network Management System (x) 1Gig links Metro-Ethernet Network Central Office Aggregation Switch Management VLAN Up to (4) 10G Uplinks Alleviates Potential Bandwidth Bottleneck Central Office Premium customers such as government and banks 1Gig Links

10 GbE Standards 10GE or 10GbE or 10 GigE standard was first published in 2002 as IEEE Std 802.3ae The following 10GBase- standards have been published: 802.3ae-2002 (fiber -SR, -LR, -ER and -LX4 PMDs) 802.3ak-2004 (-CX4 copper twin-ax InfiniBand type cable) 802.3an-2006 (10GBASE-T copper twisted pair) 10 GigE supports only full duplex links The 10 gigabit Ethernet family of standards encompasses media types for copper twisted pair (up to 100m on cat 6a or higher, 55m on cat 6 or lower) single-mode fiber (long haul) multi-mode fiber (up to 300m) Copper CX4 (up to 15m)

10G Distance Specifications Wavelength (nm) Cable Type Core Size (micron) Modal Bandwidth (Mhz*km) Cable Distance 10G-Base-SR 850nm MMF MMF OM2 OM3 OM4 62.5 62.5 50.0 50.0 50.0 160 200 400 500 2000 26 m 33 m 66 m 82 m 300 m 10GBase-LRM 1310nm OM1 62.5 220 m - OM3 50.00 260 m 10G-Base-LR 1310nm SMF G.652-10 km 10G-Base-ER 1550nm SMF G.652-40 km 10G-Base-ZR 1550nm SMF G.652-80 km

10G Distance Implications Especially copper and Multi-mode (MM) fiber Shorter Transmission Distances Mean Cable Plant upgrades Cat5, Cat5E, or Cat6 need to be Cat6A 62.5 Fiber replaced with OM3/OM4 50u Fiber Repeaters Extending distances beyond 80km on single mode Extending distance beyond 300m on MM 10G adoption is being limited in scope by these distance restrictions Almost entirely an aggregation transport method Very few FTTx connections

xtgffxxxx-100 10Gig Ethernet fiber to fiber converter (TGFF) Two slot design Protocol dependant Only support 10Gig Ethernet data rates of 10.3125 Gbps Supports 3R s (reamplify, reshape, retime) Supports variety of XFP and SFP+ modules 10GBase-SR, 10GBase-LR, 10GBase-ER, 10GBase-LRM, 10GBase-ZR, CWDM/DWDM, / LEDs for Pwr and Link/Activity for each port Model Numbers: xtgff4747-100 XFP xtgff4848-100 SFP+ Chassis Card supports management when installed in a managed chassis

WhataretheThreeR s are the Rs 3R s Reamplifying, Reshaping, Retiming Fully regenerates the signal Most SM to MM products Only reamplify 10Gig Converter Supports 3R s

10 Gig Media Converter: Application 10Gig fiber is always modular no fixed fiber ports Application Fiber extension 3R s at multimode max distance 3R s atsinglemodemaxdistance max distance Connect MM fiber to SM fiber at 10G speeds Conversion from standard wavelength to CWDM wavelength for non-msa compliant equipment

10-Gig Modules 10Gig modules are not specified in 802.3ae Specified by multi-source agreements (MSAs) The relevant MSAs for 10GbE are: XENPAK was the first MSA for 10GE and has the largest form factor. X2 and XPAK were later competing standards with smaller form factors XENPAK X2 XPAK XFP came after X2 and XPAK XFP SFP+ is the newest module standard and is smaller still and uses less power than XFP SFP+

10GbE Connector Future SFP+ SFP+ should enable lower cost 10GE optical modules to be produced SFP+ modules only do optical to electrical conversion, no clock and data recovery, putting a higher burden on the host's channel equalization SFP+ modules share a common physical form factor with legacy SFP modules, allowing higher port density than XFP and the re-use of existing designs for 24 or 48 ports in a 19" rack width As with the 1-Gig GBIC, the larger form-factor of the different connectors will give SFP+ the long term advantage and viability as 10G products become more readily available and per-connection prices drop

What is it? Extinction Ratio The extinction ratio describes a relationship between the output power when an optic is on to the output power when an optic is off It is more effective at determining the real power of an optic for distance transmission than a db rating It can easily be converted from a ratio to a db rating The equation for calculating the extinction ratio is:

10G over Twisted Pair RJ-45 Not widely in use yet 10GBase-T Mainly because not a lot of end stations with 10G needs Growing in use As more companies move to 10G, expect 10GBase-T to become more prevalent Expect SFP+ and XFP versions that have 10GBase-T interface rather than optical interfaces Leverages existing 10G port availability Leverages existing 10G port availability Expect future product releases from TN to support 10GBase-T standards

Summary 10GbE is gaining acceptance Key Distance limitations on copper 15m on CX4/Twin-ax 55m on Cat5, 5e and 6 100m on Cat6a Key distance limitations on MM fiber <33m on 62.5 micron <300m on 50 micron Fiber repeaters like the xtgff from Transition Networks can extend your 10G reach with Retime, Reshape, Reamplify (3R s)

Summary - Continued Several connector types in the field XENPAK X2/XPAK XFP SFP+ SFP+ is likely to become dominant connector type due to Size Price Simplicity i of use The Extinction Ratio is a new way to calculate distance capabilities for optics More reliable than a pure decibel number (db) Equation Includes the pure output db
