What frequency is associated with an ISO class of Ea for balanced twisted-pair cabling?

The frequency associated with an ISO class of Ea for balanced twisted-pair cabling is 500 MHz. This classification pertains to the performance requirements of cabling systems, particularly in terms of data transmission capabilities. Class Ea cabling is designed to support higher bandwidth applications, which is reflected in the 500 MHz specification.

Class Ea is significant in environments where high-speed data transmission is critical, such as for Gigabit Ethernet and similar protocols. This standard ensures that the cabling can effectively handle the increased frequency demands, thereby reducing potential issues such as crosstalk and attenuation that can occur with lower frequency cabling.

Understanding the frequency parameters is essential for ensuring that the cabling installed meets the necessary performance criteria for current and future networking technology needs.
