7. Fiber Misconceptions“Not Your Father’s Fiber” Weight Size • Perception: Copper weighs less than fiber • Fact: Fiber components are heavier, but fiber cable is lighter • Perception: Copper cable is smaller than fiber cable • Fact: Fiber is 15% smaller Rating Strength • Perception: Copper is more fire-resistant • Fact: Fiber is plenum-rated,compatible with infrastructure • Perception: Fiber is fragile • Fact: Fiber is 4+ times stronger than copper

17. A Distributed NetworkCopper and Fiber In a conventional distributed structured cabling design, the backbone cable is optical fiber. The horizontal segment of the network typically consists of twisted-pair copper cable or optical fiber cable (depending on distance). Backbone cables in an inter-building network travel from a main cross-connect (distributor) to one or more horizontal cross-connects within a telecommunication room, which includes active electronics equipment such as hubs, concentrators or switches. These would easily support a school administration network.

18. A Centralized NetworkAll Fiber Optical fiber’s bandwidth and ability to carry data over long distances is best utilized in centralized networks. Centralized networks have more unblocked bandwidth than distributed networks and therefore are better suited to support combined voice, video and data traffic requiring quality of service implementation. Optical fiber eliminates intermediate closets, thus simplifying network layout and reducing overall system cost. Classrooms are a good example of one of the places a centralized network could be implemented.

19. Zone Cabling Architecture Moves, adds or changes in an open-office environment can be accommodated quickly and efficiently through consolidation points by combining permanent feeder cabling with pre-terminated plug-and-play extender cables associated with the work area. Zone cabling is a relatively new term for a concept being used in many schools today. One good example of where it could be used is in a computer lab.

20. Standard Architectures Drive Lower Costs • TIA-568 - in 1991 • Centralized Cabling • Consolidation Points • Telecommunications Enclosures • Commonly know with “zone” cabling

21. Zone, Tiny TR, Telecom Enclosure Update • TR42.3 has drafted Telecom Enclosure (official name) • Has finished final default ballot. • Will be part of the ANSI/TIA-569-B Standard • TR42.1 has drafted a TE cabling implementation document • Final default ballot complete - • Will become an addendum for TIA 568-B.1 • Ballot Resolution Completed in February. • Final document integration this Summer.

22. Traditional Design Optical Fiber Backbone HC in the TR LEGEND: = Fiber Backbone Cable = Horizontal Cable = Telecommunications Outlet/Connector = Building Pathways and Spaces = Horizontal Cross-Connect = Telecommunications Room HC TR Offices Cubicles

23. Zone Cabling with a Telecomm Enclosure Optical Fiber Backbone HC in the TR LEGEND: = Fiber Backbone Cable = Horizontal Cable = Telecommunications Outlet/Connector = Telecomm Enclosure with a switch = Building Pathways and Spaces = Horizontal Cross-Connect = Telecommunications Room HC TR Offices Cubicles

24. School’s “Secret Weapon” • Small inexpensive switch in every class • Managed or un-managed • Covered or accessible • Really used as a media converter

34. Cost Model Background & History • Aug 2000 – Tolly Group white paper “Migrating to Fiber – The Case for Centralized Cabling” • Paper need more robust “interactive” backup model • 2001 – First version of Fiber Optic LAN Section (FOLS) cost model • Focused on SFF connectors, and media converters • Implemented conclusions of Tolly study with “real world” scenarios. • April/May 2003 – Version 2 of cost model developed • Updated new lower cost fiber and copper switches and other products • Doubled the number of scenarios • Added very low cost and Zone configurations • Jan 2004 - Simplified Data Entry Developed

35. Distributed vs. Centralized vs. Zone • Distributed • Accommodates the 100-meter limit of UTP copper cable. • Necessitates media conversion in the telecommunications room. • Typically, consists of high-speed uplinks • Centralized • Not bound by copper’s 100-meter limitation, nor do they require media conversion from one physical medium to the other. • Zone • Combines the best of Centralized and Distributed • Small telecommunications enclosures • Use fiber for distance and bandwidth • Copper for short distance final connections

36. Cost Model AssumptionsTIA FOLS Fiber-Copper Cost Models • Hierarchical star UTP vs. centralized fiber • Building “model” • 8 story, 48 ports/floor • Costs calculated on “per port” basis • Port utilization • Copper: 70% • Fiber: 90% • Fiber used in riser subsystem (both models) • Horizontal subsystem • UTP: Cat 5e or Cat6 UTP (depending on model) • Fiber: 62.5 or 50 µm multimode fiber • Telecommunications room • Copper TR: $20,000 • Fiber TR: $4,500

37. Cost Model Assumptions • Twenty-one page document details all parts of the model • Updated as the cost model modifications are made.
