Elements Of The Design
• Data transmission requirements
• Cabling components and their installation
• Pathway & Spaces where the cable is placed
8/16/2005 ADC Proprietary and Confidential 3
Data Transmission Requirements
• What applications?
– Windows or Mac applications with file transfers
– CAD or 3D modelling with file transfers
– Imaging or publishing work
– Medial or X-ray data transfers
– How many on the LAN?
– POTS or VoIP
• What network components?
– PCs, NICs, file servers, network operating system
– Hubs, switches, routers
– Printers, scanners, industrial equipment
– Remote access, VPN
• Growth allowance?
– Own building
– Long or short tenancy

Data Transmission Requirements
• Ethernet most common LAN technology (over 25
years old)
• IEEE 802.3 Carrier Sense Multiple Access with
Collision Detection CSMA/CD:
• 3y 100BASE-T on Cat3
• 3ab 1000BASE-T on Cat5E
on Cat6
• 3z 1000BASE-SX on OF
-LX on OF
• Full Duplex with flow control
methodology is industry preferred
• Half Duplex is supported by only
a few vendor specific gigabit
products
MAC = Media Access Control
PHY = Physical Layer = OF or Cu
