资料简介: Introduction How do you know if Category 5 is good enough for your application? Is a Class A link better than a Class F link? What is the ISO/IEC/JTC1/SC25/WG3 US TAG up to and should I care? Are changes in international standards likely to affect me? What do I really need to know about cabling standards? What simple things can I do to minimize network downtime? A great deal of confusion surrounds network cabling issues. Yet cabling accounts for 50-70% of all LAN failures, and the resulting network downtime costs organizations thousands of dollars per year in lost productivity, idle resources, and lost revenues. If you are a network administrator, it is essential to understand how to get the best performance from your cabling investment, and find faults quickly when they occur. If you are a cable installer, you need to be up to date on the latest cable installation and conformance techniques to ensure your work meets changing international standards.
