A thin-diameter wire (22 to 26 gauge) commonly used for telephone and network cabling. The wires are twisted around each other to minimize interference from other twisted pairs in the cable. Alexander ...

Why should twisted-pair cabling, used in large quantities to carry 4-kHz voice signals in the phone system, suddenly work well at 100 MHz and beyond? The simple answer is that it doesn’t. All ...

Spoiler summary: It only takes -60 dB of mode conversion to fail an EMC compliance test if this common signal gets out on unshielded twisted pair cables. If a common mode choke is used, as much as -20 ...

With many appliances transitioning to Internet Protocol (IP) networks, the Ethernet interface finds itself in these products for the first time. This makes electromagnetic compliance (EMC) a challenge ...

Moving vast amounts of data between two points quickly, reliably and economically is what many designers are facing regularly when building their systems. When it comes to using copper cables as a ...

When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. If you're an old geezer like me, the idea of using unshielded cable to run audio is still a ...

This article was updated March 31, 2023. It was originally published Jan. 8, 2016. Engineers and designers who don’t regularly work with CAT data of cables, and even some that do, can get confused ...

Copper cabling, unshielded, in which a nominal level of interference is mitigated based on the twisting of two conductors (a pair) around each other for the entire length of the cable. Twisted pair ...
