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 this custom limit 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. You must consult with the designer of the cabling system.
Optionally, users could set Maximum Length and Maximum 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 (@ 850 nm).
More information on the use of custom limits is available during the Certified Cabling Test Training module VERSIVFO.

| 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 @ 1550nm (dB/km) | 1,00 | 1,00 |
