Much like the weakest link in a chain, a patch cord with poor transmission characteristics can degrade the performance of any cabling system significantly, even when used with the best performing outlets and cable.

Recent studies have shown that up to 83% of Category 6 patch cords fail to meet the requirements of TIA/EIA-568-B. Siemon was confident that its patch cords met or exceeded the standard 100% of the time as their investment in modular patch cord quality assurance is unparalleled in the industry.

John Siemon, Vice President of Global Operations said, “We tested our category 6 MC6™ patch cords against 6 different competitive brands. All cords, including our own, were randomly purchased through distribution. A total of twenty 0.9 metre and twenty 4.6 metre patch cords of each brand were evaluated for NEXT performance on all six combinations in both directions, providing a total of 12 measurements per cord.

“Only Siemon and one other manufacturer passed all 40 cords. A significant number of cords from five other manufacturers failed.”

The only real way to guarantee modular cord performance is to test every cord across all pairs combinations, in both directions, after assembly.

100% factory transmission testing is critical to ensure the quality of the assembly process. Without 100% transmission testing during production, poor performing cords are not detected and end up in customer installations.

“To ensure our modular patch cords deliver guaranteed channel performance, Siemon transmission tests 100% of its MC6™ modular patch cords on a laboratory grade network analyser. No cord leaves our factory without passing our stringent testing.

“Not every patch cord is created equal, so be sure to specify patch cords that are 100% factory transmission tested.”
