Introduction
Limits specified by ISO/IEC11801:2017 and ISO/IEC14763-3:2014 (Information technology -- Implementation and operation of customer premises cabling -- Part 3: Testing of optical fibre cabling) are no longer adequate to evaluate the quality of recently installed fiber optic infrastructure.
This article was recently updated for firmware version 6.0 (January 2019).
Solution
Use these recommended 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 |
|---|---|---|---|---|---|---|
| Connector Loss (Max) | 0.30 | 0.30 | 0.30 | 0.30 | 0.30 | 0.30 |
| Connector Loss (Min) | N/A | N/A | N/A | N/A | N/A | N/A |
| 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.
