5.1.3 Basic link connection
Similar to Permanent Link the Basic Link connection is used when the fixed installed
section of cabling is tested. When measuring basic link use reference (test equipment)
patch cables together with the channel adapter.
This connection is no longer recognized in latest versions standards and can be
replaced with a newer permanent link.
5.1.4 Optical fiber connection
Refer to with MultiLAN350 compatible Optical power meter User Manual to learn more
about test connections and setups for testing fiber optic cables.
The results from the optical power meter can then be sent to MultiLAN350 that offers:
- comparison of results against limits in common LAN cable standards,
- storing measuring results into MultiLAN350 memory base,
- creating Test Reports with LANlink.
5.2 Presentation of results
5.2.1 Summary results - Copper cables
NEXT, PSNEXT, ELFEXT, RETURN LOSS, ATTENUATION, ACR, PSACR
Presentation as worst margin values with respect to the applied test limit
The result is presented as the worst case margin to the given limit together with the
associated frequency, limit and pair. The worst pair (pair combination) is marked with a
point.
Specialities
The worst case margin is not reported for attenuation.
The return loss margin is not relevant where attenuation is below 3 dB.
Presentation as worst result value
The result is presented as the worst measurement value, which may not necessarily
come closest to the applied test limit. In Autotest the associated frequency, limit and
pair are stored.
Speciality
The return loss result is not relevant where attenuation is below 3 dB.
