The CA Score
goes beyond standard decibel-based testing to real-world scenarios that are designed to measure how well cables perform under the stress of converging applications. The CA Score is based on the results of a 100-meter, four-connector channel test designed to measure network infrastructure performance under the stress of real-world applications. The CA score testing involves simultaneous transmission of Voice, Data, Video, and Power over Ethernet (PoE) through a cabling channel. During the test, real-world conditions such as heat and nearby voltage spikes are simulated to stress the cabling as they would be in the installation environment.
The results of several tests are recorded: Mean Opinion Score (MOS) for VoIP performance, Media Loss Rate (MLR) for Video performance, Bit Error Rate (BER) for Data performance, and Heat Rise for PoE performance. These results are then entered into a proprietary algorithm that calculates the results into a CA Score between 1 and 10. A score of 8.6 or higher is considered excellent and would equate to a near flawless user experience even while under stressed conditions. A score of 10 is theoretically impossible because this would require a room temperature cable to have 0 DC resistance and therefore 0 heat generated when transmitting 100W of PoE.
