Introduction
As application limits continue to become more stringent, limits proposed by ISO and ANSI are no longer acceptable to evaluate the quality of a fiber optic infrastructure. Using recent ISO and ANSI test limits is especially problematic when testing multi-mode fiber optic links with more than two connections, which is often the case in datacenters.
Solution
Use this custom limit for length/loss testing.
Optionally, users could set Maximum Length and Maximum Overall Loss limits in accordance with the application. For example, if the link is OM3 multimode fiber and the application is IEEE 10GBASE-SR, these values would be respectively 300m and 2,60dB (@ 850 nm).
More information on the use of custom limits is available during the Certified Cabling Test Training module VERSIVFO.
