The NEXT value indicates the extent to which the cross-talk between two neighbouring core pairs in a cable is suppressed. Cross-talk is due to electromagnetic fields that occur as a result of signal transmission and are induced into the other core pair. The Near End Crosstalk value indicates how strongly the signal of a core […]
Basically, it can be said that the darker, the better, as there are more protective colour particles in such colours. For this reason, black is the best colour in terms of durability under exposure to UV light. Vote Up +0 Vote Down -0You already voted!
ATEX groups zones according to the potential for explosion. In principle, it can be said that materials are to be used that are similar to a heavy rubber material. As this cannot always be guaranteed for technical manufacturing reasons , materials such as PUR and TPE can also be used for certain zones. Vote Up +0 […]
PoE means “Power over Ethernet” and describes the ability of the cable to transfer not only data but also energy to the load. For this, a certain voltage and certain current carrying capacity are needed. The voltage is less than 60V and the voltage level of the cable must therefore be at least 300V. The […]
EIA/TIA-568-A and EIA/TIA-568-B are standards for the contacting of eight-pin Ethernet RJ-45 connectors. In functional terms, there are no differences and the only visual difference is that core pairs 2 and 3 (orange/white & green/white) are swapped round. The only thing that is important here is that contacting is consistently in line with the standards. […]
