OptiFiber Pro custom test limit

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. This is especially problematic when testing multi-mode firber optic links with more than two connections.

 

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.

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