7 Fiber-Copper Cable Shipments Cable Product Value Shipments Copper 59% $2.6 Billion Fiber 41% Copper cable still dominant Declining market Declining copper cable prices : 2007: Major shift to fiber cable Major fiber applications Gigabit Ethernet Fiber to the zone Fiber to the desk Storage area networks Copper 39% $4.1 Billion Fiber 61% Source: FTM Consulting, ftm.consulting@gte.net 7

8 UTP Copper Selecting the Horizontal Media UTP Copper or Multimode Fiber? Perceived lowest system cost The easy choice Almost universal installer familiarity Smooth Ethernet upgrade path More complex to install & test Susceptible to EMI, RFI & crosstalk Limited cable pull strength 100 meter 1 Gbps Shorter useful life Multimode fiber Higher bandwidth Simplified installation Significantly lower testing costs Lower initial installed costs with centralized architecture Lower life-cycle infrastructure costs Smooth Ethernet upgrade path Immunity to EMI, RFI & crosstalk Superior cable pull strength Perception of complexity Less installer familiarity Electronics still higher priced 8

9 So, Why Not More Fiber? Are Costs Really Higher? Perception: : fiber is still more expensive than copper Reality: : fiber is less expensive in many applications Network lifecycle costs not the primary driver Erroneous assumption: fiber networks should be designed exactly like copper networks Designing fiber networks based upon its capabilities saves thousands of dollars compared to copper 9

39 Moving Beyond 10/100 Does Need Exist for 100/1000 Standard? TIA FO-4.2 Task Group wanted to know TIA LAN Section/BICSI survey developed Survey conducted 4Q2001 ed to 10,000 BICSI members in 40 countries Total valid responses: 614 (~6%)( Excellent results 100/1000 questions Qualify the respondent Determine need for 100/1000 standard 39

41 BICSI Survey Key Question Interest in 100/1000 Mbps Fiber Ethernet? The original Fast Ethernet (100 Mbps) IEEE standard for 100BASE-FX operates at the long (1300 nm) wavelength. However, the vast majority of multimode fiber Gigabit Ethernet electronics being deployed today operates at the more economical short (850 nm) wavelength. There is a wavelength disparity between 100BASE-FX and 1000BASE-SX SX that prevents interoperability. Would your customers be interested in standardized 100/1000 Ethernet optical fiber electronic products that could auto-negotiate (automatically switch up or down) between the two speeds while taking advantage of fiber s extended distance capability? 41

42 BICSI Survey Results Strong Interest Indicated 89% positive response for new standard Yes: 547 No: 67 Clear support for short wavelength (850 nm) 100/1000 standard indicated Testing at ADC determined 10/100/1000 system feasible 67, 11% 547, 89% Yes No 42

43 Tri-Speed Fiber Ethernet Why Do We Need It? A 10/100/1000 Mbps standard would solidify the use of optical fiber for LAN/MAN/WAN applications It would have the same effect as the ANSI/TIA/EIA-568 Category 5 specification had for UTP applications Ethernet deployments are challenging traditional distances Enterprise and carrier customers want it! Fiber solutions that don t require forklift upgrades Network elements that support different Ethernet speeds Rate control without truck rolls Tariffs that will be based on bandwidth allocation 43

45 FTTx Application 1 Carrier SONET Ring with Optical Service to Customer Most customers are outside of the 100m UTP distance limitation. Optical links using conversion equipment is the only solution that meets the multi speed s requirement. At present only 10/100 Mbps can be supported.

48 Summary Where Is Fiber to the Desk Cost Effective Today? The market outlook for enterprise fiber is excellent Myth: Fiber to the desk is much more expensive than copper Reality: New FOLS cost models show significant FTTD savings FTTD less than UTP copper in all 12 scenarios examined Centralized fiber also offers significant additional advantages Fiber-to to-the-zone saves big & brings fiber closer than hierarchical star Emerging Tri-Speed Ethernet standard will facilitate fiber in the LAN, the MAN, and the WAN TIA Fiber Optics LAN Section provides the information that helps users make educated choices 48
