Channels, Testing and Performance Verification<br />
Connectivity components play a major part of the performance of any portion of the network.<br />
This is especially true in the portion of the horizontal segment of the network called the channel.<br />
Channels<br />
The channel consists of the cable and components that connects the desktop to the active<br />
equipment in the telecommunications or equipment rooms. For twisted pair installations,<br />
the channel includes the equipment cord at the desktop, the horizontal cable, the<br />
telecommunications outlet (and the consolidation point, if installed), the patch panel or<br />
termination in the telecommunications or equipment rooms and the patch cable to the active<br />
equipment.<br />
Any relevant measure of network performance must take the channel into account. Cable must<br />
be matched with properly engineered components to produce optimum performance.<br />
Standard testing for a channel includes what are called 3, 4 and 6 connector specimens<br />
(shown below - installed cable is shown below in blue/patch cords are shown as orange).<br />
The 3 connector specimen is a traditional cord/permanent link/patch cord configuration.<br />
The 4 connector specimen adds a consolidation point.<br />
The 6 connector specimen further adds an additional patch cord and outlet in the<br />
telecommunications room.<br />

<strong>CommScope</strong> participates in third-party verification to ensure quality performance of our<br />
structured cabling products. This verification program is a process in which our products are<br />
tested by a third- party laboratory like UL or ETL SEMKO, a division of Intertek.<br />
The laboratory performs extensive tests to confirm that our products meet and exceed required<br />
standards and to verify that our product performance claims are accurate.<br />
