Data Center Cabling Standards
Data Center Standards
• TIA 942: Telecommunications Infrastructure Standard, April 2005
– Substantial, Available, American
• EN 50173-5: Information technology – Data Centers
– Smaller scope, European perspective
• ISO/IEC Draft 24764: Information technology
– Global Generic Cabling for Data Centers
Hierarchical Structure of Data Centers
Tiers• The Uptime institute defined 4 levels of reliability for Data
Centers
Not much time
for re-cabling
Data Center Cable Types
• Fiber media types:
– Singlemode fiber– Multimode fiber – TIA: recommendation OM3 (XG) | ISO min. OM3 (XG)
• Copper media types:
– TIA: min. Cat. 6 | ISO: minimum Class E A !!!!!!!

Premium Passive Solutions for Data Center
• DC cabling requirements aredifferent from the ones in Office Networks
• Static vs. Dynamic
– Easy deployment (weekend work/testing)– High performance– Structured scalability– Fast & easy MAC‘s (operational cost)– Functional Security (less human errors)– High density (cost of space)– Effective cable management– Availability (less planning, less downtime)– Cooling/airflow support
Data Center Applications & Technologies
Today & Tomorrow
GBE/10GBE
• GigaBit Ethernet
– OM1/OM2/OM3 for fiber (1000Base-SX/LX)– Cat.5e for copper (1000Base-T)
• 10GigaBit Ethernet
– OM3 recommended for fiber (10GBase-SR)– Cat.6A/Cat.7/Cat.7A for copper (10GBase-T)

Pre-terminated Plug & Play
Modular Cabling Solutionfor Copper & Fiber
MRJ21 MPO 1€
High Density Pre-terminated Solutions
• Pre-terminated MRJ21 Copper System
• High Density with 6 GBE Channels per cable
• Pre-terminated MPO Fiber System
• High Density with 12 or 72 fibers per cable
ISO/IEC 24764 Data Center Standard
Backbone
Horizontal
• Combines high density and ease of maintenance with energy saving:
• Doubles GBE switch capacity compared to RJ45 interface
• Utilize existing chassis
• Flexibility
• Rapid installation / change-out• Fewer cables to manage on the switch

High-density Pre-terminated Solutions
• Common Systems features:
– High-density and/or modular connectivity– The simplicity of a “Plug&Go” installation– Factory tested– Less Installation time in avg. 5x faster
than traditional termination/panel– Space saving in average 30%
(pathways & spaces)– Support of cooling concepts– Easy Scalability
Recall: DC Premium Cabling Requirements
– Easy deployment(weekend work/testing)
– High performance– Structured scalability– Fast & easy MAC‘s– Functional Security
(less human errors)– High density– Effective cable management– Availability
(less planning, less downtime)– Cooling support
Zero U Cable Management
Why Cable Management ?
• Does this look familiar?
– Unmanaged and unstructured connections
– No documentation– 30-40% abandoned patch cords
after 1 year of operation– Dead ports in switches and cable
runs 30-40% unused capacity– MAC time > 1h per port– Adds up to 150% of operational
cost– Adds up to 200% of floorspace
needed – Heat sinks creation (blocking of
air flow)
Zero U Cable Management Technology
• Zero U Corner Brackets combined with AngledPatch Panels
– Eliminates the need for horizontal cable managers– Uses unused valuable cabinet space– Effectively increase of cabinet density– Available for Copper & Fiber
