Balanced twisted-pair cabling channel performance associates a frequency of 100 MHz with ISO class _____.

Balanced twisted-pair cabling channels are categorized based on their ability to transmit data at specific frequencies and performance levels. In this context, the correct classification that associates with a frequency of 100 MHz is ISO Class D.

ISO Class D is specified to support data rates up to 100 Mbps using a bandwidth of 100 MHz. This class includes cables like Category 5e, which is designed for Ethernet networking and other data transmission applications. The performance metrics associated with this class ensure that the cabling can handle the signal integrity requirements necessary for high-speed data communication.

Understanding these classifications is essential for selecting the appropriate cabling for network installations, as they directly impact the reliability and performance of data transmission in various environments.
