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.

 

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

Splice Loss (Max) 0.15 0.15 0.15 0.15 0.15 0.15
Splice Loss (Min) N/A N/A N/A N/A N/A N/A
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.
