OptiFiber Pro custom test limit

Introduction

As application limits continue to become more stringent, limits proposed by recent versions of ISO and ANSI standards are no longer adequate to evaluate the quality of a fiber optic infrastructure. This is especially problematic when testing multi-mode firber optic links.

 

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.
