Introduction
It is our opinion that the length/loss limits to be used with ISO/IEC14763-3:2014 (Information technology -- Implementation and operation of customer premises cabling -- Part 3: Testing of optical fibre cabling) iare no longer adequate to evaluate the quality of a recently installed fiber optic link; they are too relaxed.
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 |
