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 fiber optic links with more than two connections, which is often the case in datacenters.

 

Solution

We recommend this custom limit during length/loss testing. End-users could set Maximum Length and Maximum Overall Loss in accordance with the application limit.  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 (@ 850 nm). More information is available during the Certified Cabling Test Training module VERSIVFO.

Parameter Default value Recommended value
Length (m) 2000,0 2000,0
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
