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 ...

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 ...

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 ...

The IEEE in June approved the publication of the 802.3an-2006 standard, otherwise known as 10GBase-T. This document describes a physical layer (PHY) transmission device for 10Gbps Ethernet over ...

Welcome to another post in the series by Nick Locke, of Nicab Ltd, who has more than 15 years experience in the electronics manufacturing industry specialising in interconnection cable assembly. Here ...

Category 5 (CAT 5) cable is a multipair (usually four-pair) cable that consists of twisted-pair conductors, used mainly for data transmission. Basic CAT 5 cable was designed for characteristics of up ...

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 ...

Robert Metcalfe, David Boggs, and their associates really started something back in 1973 when they invented Ethernet. It started out as just one of many contenders for LAN supremacy and essentially ...

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 ...
