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
Unless specified otherwise, use these values to create one custom limit for testing PC/UPC terminated links and a second custom limit for testing APC terminated links. These limits mimic the limits proposed in our article CertiFiber_Pro_custom_test_limit.

(*) APC style connectors aren't used on multi-mode fiber links. You may decide to keep the default values for multi-mode wavelengths.
