Testing patch cable ethernet
L-com's network cable tester and RJ45 Ethernet cable tester products are available for testing coaxial, fiber optic, Cat5/5e/6, USB, Firewire, Telco RJ11/12 cables and more. We offer network cable and network bandwidth tester equipment from well known manufacturers such as Fluke Networks, AEMC, and Advanced Fiber Solutions. Network Channel Testing Network Channel Testing is a method used to verify performance from the workstation to the hub/switch including patch cords. Channel Testing is not accurate for individual patch cords. Both installers and IT professionals conduct this type of testing to insure that the entire cable system is capable of handling network traffic. Channel Testing differs from Permanent Link Testing in that it includes the patch cords on both ends of the installation. Often, patch cords are overlooked as the cause of network failures. Permanent Link Testing Permanent Link Testing is the preferred method used by installers to certify a cable installation at a customer site. This type of testing verifies the installation by measuring many factors such as cable lengths, NEXT, FEXT and Return Loss. Several certification testers exist on the market including Fluke Networks DTX-1800 Series products. This type of tester features a Permanent Link adapter that connects from a workstation outlet to the telecom closet outlet. Continuity Testing Continuity Testing is the most basic form of testing conducted on cables. These types of testers look for opens, shorts or crossed connections. For Ethernet, this type of testing does not confirm network transmission capability. The most common mistake in cable pin-out is an EIA568 A to B cross. A simple continuity tester such as L-com's TL- N044-000- R can easily find this error without the expense of a certification tester. Wire Mapping / LAN but electrically, there is a big difference and it all has to do with bandwidth. The more data you want to shove through a cable, the higher the frequency of the signal is, and a data pair whose dimensions and spacing are consistent enough to handle ten Megahertz won't necessarily do at a hundred Megahertz because the materials and dimensions become increasingly critical at higher frequencies. It's all about tolerances. Cat 5e cable has got to meet specification requirements up to 100 MHz; Cat 6 takes the spec.
