Conclusion
For optimum performance of your 1000BASE-T product, it is important to fully qualify your cable
installation and ensure that it meets or exceeds ANSI/EIA/TIA-568-A:1995 or ISO/IEC
11801:1995 Category 5 specifications. Install Category 5e cable where possible, including patch
panel cables. Minimize transition points, jacket removal, and untwisted lengths. Cable bundles
must be correctly installed to meet the requirements in ANSI/EIA/TIA-568A-3.
