Introduction

Limits specified by ISO/IEC11801:2017 and ISO/IEC14763-3:2014 (Information technology -- Implementation and operation of customer premises cabling -- Part 3: Testing of optical fibre cabling) are no longer adequate to evaluate the quality of recently installed fiber optic infrastructure.

This article was recently updated for firmware version 6.0 (January 2019).

 

Solution

Use these recommended values and create at least one custom limit for testing PC and UPC terminated links and a second custom limit for testing APC terminated links.

 

Maximum length for PC, UPC and APC terminated links

Parameter Recommended value
Length (m) N/A

 

General Settings for PC, UPC and APC terminated links

Parameter 850nm 1300nm 1310nm 1490nm 1550nm 1625nm
Overall Loss (Max) N/A N/A N/A N/A N/A N/A
Overall Loss (Min) N/A N/A N/A N/A N/A N/A
Optical Return Loss N/A N/A N/A N/A N/A N/A
Segment Attenuation Coefficient (Max) 3.0 1.5 1.0 1.0 1.0 1.0
Segment Attenuation Coefficient (Min) N/A N/A N/A N/A N/A N/A

 

Event Settings for PC and UPC terminated links

Parameter 850nm 1300nm 1310nm 1490nm 1550nm 1625nm
Connector Loss (Max) 0.30 0.30 0.30 0.30 0.30 0.30
