Converged Application Score (CA Score)

How well will your cabling infrastructure support convergence?

To accommodate bandwidth expansion you need cabling that offers the ideal balance between delivering data AND power. This requires a new way of testing and evaluating cabling performance. Nexans’ Converged Applications (CA) score defines how the cabling network’s performance will affect the user’s experience. Using realistic test scenarios, it measures how network infrastructure will perform against future demand and converging applications. The CA score is an indicator of IP traffic protection as it is related to cabling system performance.

Empirical testing on these channels includes:

  • Mean Opinion Score (MOS) – A quality of service metric used to measure VoIP
  • Frame Error Rate (FER) – A measurement of the integrity of IP data transmission
  • Media Loss Rate (MLR) – A quality of service metric used mainly to measure IP video
  • Heat Rise from PoE – A measurement of how efficiently the cabling dissipates heat

Nexans feeds these test results into an algorithm that incorporates total channel bandwidth as well as Signal to Noise Ratio values and reach capability for 1, 2.5, 5, and 10 Gbps Ethernet. The output is the Converged Application score for each channel tested in a range between 1 and 30.

In short, the Nexans CA score is an indicator of the user experience based on real world applications and environmental conditions.
