Even skilled cable installers have issues with Class-6a cabling, and it does not sound like you’ve gotten the right (costly) testing instruments to be able to certify the cabling class (see this reply for the fundamental required exams).
This seems to be solid-core cable that’s appropriate for horizontal (in-the-wall) cabling, which needs to be terminated on wall sockets, then run by means of the take a look at suite. The connectors look like plugs which can be usually appropriate just for stranded cable that’s used for patch cords. For Class-6 and Class-6a, you may be unable to construct a patch twine that may go the class take a look at suite. It’s essential to purchase factory-built patch cords, and the usual (ANSI/TIA/EIA 568, Business Constructing Telecommunication Cabling Customary) says that you’re not allowed to construct these patch cords.
Your image reveals an improperly terminated cable. The cable sheath is stripped too far again and the pairs are untwisted too far, and the cable is shielded, which means that you’d want connectors and tools that may use shielded cabling, and your connectors usually are not shielded. The protect makes up for poor cable efficiency, however it should be steady, and grounded, not less than, on each ends, in any other case the cable won’t carry out to specs. See Shielded and unshielded twisted-pair cable revisited:
If STP cable is mixed with improperly shielded connectors,
connecting {hardware} or retailers, or if the foil protect itself is
broken, general sign high quality will probably be degraded. This, in flip, can
end in degraded emission and immunity efficiency. Due to this fact, for a
shielded cabling system to completely cut back interference, each
element inside that system should be absolutely and seamlessly shielded, as
nicely as correctly put in and maintained.An STP cabling system additionally requires good grounding and earthing
practices due to the presence of the protect. An improperly
grounded system could be a major supply of emissions and interference.
Whether or not this floor is at one finish or each ends of the cable run
relies on the frequency at which a given software is operating. For
high-frequency alerts, an STP cabling system should be grounded, at
minimal, at each ends of the cable run, and it should be steady. A
protect grounded at just one finish just isn’t efficient towards
magnetic-field interference.
