Updates and Clarifications

Today, users not only need connectivity testing but also performance testing to ensure that a link will support high-bandwidth applications. To allow contractors to test links before patch cords or equipment cords are installed, the TIA channel performance task group, formerly known as the link performance task group, has defined a "basic link," previously known as the "contractor`s link." A basic link includes up to 90 meters of uninterrupted UTP cable with connecting hardware on each end. This

Today, users not only need connectivity testing but also performance testing to ensure that a link will support high-bandwidth applications.
