Media SelectionDesign Considerations per TIA-942
Flexibility with respect to supported services
Required useful life of cabling
Facility site/size & occupant population
Channel capacity within the cabling system
Equipment vendor recommendations or specifications
Same facility architecture if different media types used

Data Center Cabling RecommendationsTransmission Media – Normative “Required”
100-ohm twisted-pair copper cable– Category 3 or 5e allowed– Category 6 recommended
Multimode fiber optic cable– 62.5/125 µm or 50/125 µm allowed– 50/125 µm 850 nm laser optimized multimode fiber
recommendedSinglemode optical fiber cable75-ohm coaxial cable– Type 734 & 735 cable– Type T1.404 coaxial connector

Data Center CablingDesign Recommendations (Informative) - “Optional”
Copper design (informative)– Adequate spacing for labeling on each patch panel– Label each port per Annex B and ANSI/TIA/EIA-606-A
Fiber design (informative)– Installation time reductions– Multi-fiber increments & multi-fiber connectors– Pre-calculated, pre-terminated multi-fiber ribbon assemblies– Consider performance effects of additional connections

Look for polishing techniques yielding ideal tip geometryEnd-face quality a key factor for maximum link performanceObjectives: minimum insertion loss; maximum return loss
Ideal polish: connector ferrule/fiberend-face scan showing ideal contour
Poor polish: fiber depressed intoferrule, causing poor performance

SummaryData Centers & SANs: Rapidly Growing SCS Applications
Vast amounts of new information being created, communicated & stored
Legislation & other business priorities impacting data center & storage area network growth
The TIA-942 Data Center Standard applies structured cabling principles as TIA/EIA-568 did for commercial buildings
Careful choice of structured cabling system products should span multiple of generations of data center systems
