improper grounding ofcommunication systemsleads to $500 million / year

of damage to property andequipment due tolightning.

Why a grounding and bonding system?

Human

Equipment safety

Against

Lightning surges

Power grid quality issues

Electrostatic Discharges

Why 3rd pin not sufficient?not able to neutralize high frequency noise

Choosing the AppropriateCabling MediaChoosing the AppropriateCabling MediaFlexibility with respect to supportedservices

Required useful life of cablingFacility/site size and occupantpopulation

Equipment vendor recommendations

or specifications

Channel capacity within the cablingsystem

Category 6 minimum

recommendationfor horizontal cabling

50/125 micron 850 nm laseroptimized multimode fiber isrecommended formost backbone applications

Structured Cabling Standards Organizations

International Electrical & Electronic Engineers (IEEE)

International active network equipment standards

Computer devices and optical/electrical interfaces to cablingsystems

IEEE 802.3an (10GBaseT)

International Standards Organization (ISO)

International cabling infrastructure standards

UTP, STP, SCTP, coaxial and fiber optic systems

ISO 11801 (Cat 6A) & TR 24750 (Cat 6 migration)

Telecommunications Industry Association (TIA)

North America cabling infrastructure standards

UTP, fiber optic and coaxial systems

EIA/TIA 568B ( Cat 6A) & TSB-155 (Cat 6 migration)

Cabling for 10GBASE-T

IAugmented Cat 6 is vastly different from

standard Cat 6ICat 6 will not support 10GBase-T up to 100m

I Cabling systems should always support100m

IThere is no in-between

I Youll either run at a full 10G or theelectronicswill throttle back to 1G!

ITuned systems required not open architectures

IShort Reach Mode operates at lengths of > 30meters Category 6A.
