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. Using recent ISO and ANSI test limits is especially problematic when testing multi-mode fiber optic links with more than two connections, which is often the case in data centers.

 

Solution

Use these custom limits for length/loss testing of LC, SC, ST, FC and E2000 terminated fiber optic links. We cannot and will not advise as to what is a suitable test limit for MPO/MTP. You must consult with the designer of that cabling system.

Users could decide to set optional Length and Overall Loss limits in accordance with the application.  For example: if the link is OM3 multimode fiber and the application is IEEE 10GBASE-SR, these values would be respectively 300m and 2,60dB (@ 850nm). 

More information on the use of custom limits is available during the Certified Cabling Test Training module VERSIVFO.

Parameter Default value Recommended value
Length (m) 2000 or 5000 N/A
Connection Loss (dB) 0,75 0,30
Splice Loss (dB) 0,30 0,15
Loss/km @ 850nm (dB/km) 3,00 3,00
Loss/km @ 1300nm (dB/km) 1,50 1,50
Loss/km @ 1310nm (dB/km) 1,00 1,00
Loss/km @ 1550nm (dB/km) 1,00 1,00
