Selecting the Horizontal MediaUTP Copper or Multimode Fiber
UTP Copper• Perceived Lowest System Cost• The “easy” Choice• Universal Familiarity• Smooth Ethernet Upgrade Path• More Complex to Install and Test• Susceptible to EMI, RFI & Crosstalk• Limited Cable Pull Strength• 100 Meter Maximum at 1 Gbps• Shorter Useful Life• Not “Future Proof”
Multimode Fiber• Higher Bandwidth• Immunity to EMI, RFI & Crosstalk• Greatly Simplified Installation• Greatly Simplified Testing• Enables Centralized Cabling• Superior Cable Pull Strength• Lower Initial Installed Costs w/Centralized Architecture• Lower Life-Cycle Infrastructure Cost• Cost Effective Ethernet Migration• “Future Proof”• Perception of Complexity• Less Installer Familiarity• Electronics Still Priced Higher

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 • Erroneous Assumption: Fiber networks should be designed and installed exactly like copper networks Reality! The installation is in fact much different
• Erroneous Assumption: Fiber is more difficult to install & test Reality! Fiber is much easier to install and test
• Finally: Designing fiber networks based upon its capabilities saves thousands of dollars compared to copper
Comparing Fiber - Copper CostsSeveral Comprehensive Studies

TIA Fiber Optics LAN Section, November 2001• First Generation Cost Model• Very Popular Web Site Download
TIA Fiber Optics LAN Section, July 2003• Second Generation Cost Model• New Model Available For Download: www.fols.org• Also Visit Pearson Technologies Web Site: www.ptnowire.com
Second Generation Cost ModelSignificant Market Changes
• UTP Component Prices Have DECREASED• Fiber Component Prices Have DECREASED• Fiber Transciever Prices Have DECREASED
Long wavelength (1300 nm) substantial price decrease
Short wavelength (850 nm) have also decreased• Overall Network Costs Have DECREASED
