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.
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.
 
This article has been updated to accomodate the changes in firmware version 6.0 (January 2019).

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.

 

Maximum length for PC, UPC and APC terminated links

Parameter (m) Recommended value
Length N/A

 

General Settings for PC, UPC and APC terminated links

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

 

Event Settings for PC and UPC terminated links

Parameter (dB) 850nm 1300nm 1310nm 1490nm 1550nm 1625nm

Reflectance (Max) -35.00 -35.00 -45.00 -45.00 -45.00 -45.00
Reflectance (Min) N/A N/A N/A N/A N/A N/A

 

Event Settings for APC terminated links

Parameter (dB) 850nm* 1300nm* 1310nm 1490nm 1550nm 1625nm
Connector Loss (Max)     0.30 0.30 0.30 0.30
Connector Loss (Min)     N/A N/A N/A N/A
Splice Loss (Max)     0.30 0.30 0.30 0.30
Splice Loss (Min)     N/A N/A N/A N/A
Reflectance (Max)     -65.00 -65.00 -65.00 -65.00
Reflectance (Min)     N/A N/A N/A N/A

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