An Ethernet crossover cable is a type of Ethernet cable used to connect computing devices together directly where they would normally be connected via a network switch, hub or router, such as directly connecting two personal computers via their network adapters. Typical uses are: router to router, switch to switch, pc to pc, router to pc (Note: router and pc are LIKE devices, because both are DTE. Caution: home routers already have built-in adapter,so you can use straight through cable directly)
Cable management refers to an important step during the installation of building services (ie electrical services) and the subsequent installation of equipment providing means to tidily secure electrical, data, and other cables. The term is often used interchangeably to refer to products used for the purpose of managing cables or to the workmanship carried out to cables whilst being installed.
The purpose of cable management is twofold: to support the cables whilst being routed through the building from Point A to B (often called containment), and to make subsequent management of the cab...
A cable tester is an electronic device used to verify the electrical connections in a cable or other wired assembly. Generally a cable tester consists of:
1.A source of electric current, 2.A volt meter, 3.A switching matrix used to connect the current source and the volt meter to all of the contact points in a cable. In addition to these parts a cable tester may also have a microcontroller and a display to automate the testing process and display the testing results.
A cable tester is used to verify that all of the intended connections exist and that there are no unintended connections i...
