Cable Testing and Certification

10 Nov 2013
Test-Um's NT955 Validator-NT™ is an all-in-one network management tool with a 4-inch color LCD screen. We will use this tool to certify, identify, configure and document your Ethernet network. The Validator-NT provides every feature we need to test, trace and tune your Ethernet network.

This powerful planning and certification tool tests speed and performance using the latest nt955-cable-testertechnical advances in digital measurement. It defines the job, makes the tests, prints results and stores data. Our Validator-NT measures and presents fast, clear speed and performance results up to 1 Gigabit.

And the software lets us lay out a floor plan, document and print test results plus archive jobs for future reference. It ties together all the different cable criteria found in complex voice/data/video installations. Then it presents concise information in printed reports while storing data for future use.

Cat5/5e Network Cabling Usage and Methods

27 Aug 2009

Category 5


Ethernet_RJ45_connectorCategory 5 cable includes four twisted pairs in a single cable jacket. This use of balanced lines helps preserve a high signal-to-noise ratio despite interference from both external sources and other pairs. It is most commonly used for 100 Mbit/s office computer networks, such as 100BaseTX Ethernet, although IEEE 802.3ab defines standards for 1000BaseT - Gigabit Ethernet over category 5 cable.

Category 5e


Cat 5e cable is an enhanced version of Cat 5 that adds specifications for far end crosstalk. Although 1000BaseT was designed for use with Cat 5 cable, the tighter specifications associated with Cat 5e cable and connectors make it an excellent choice for use with 1000BaseT. Despite the stricter performance specifications, Cat 5e cable does not enable longer cable distances for Ethernet networks: cables are still limited to a maximum of 100m (328 ft) in length.

Connectors and other information

Taking these things into account, building wiring (for example, the wiring inside the wall that connects a wall socket to a central patch panel) is solid core, while patch cables (for example, the movable cable that plugs into the wall socket on one end and a computer on the other) are stranded. Outer insulation is typically PVC or Plenum. Plenum cable is designed to go into drop ceilings that are used as air returns for the air-conditioning systems in modern office buildings.

Nearly always, 8P8C modular connectors, commonly referred to as "RJ-45", are used for connecting category 5 cable.

Choosing between Cat5e and Cat6 at your Office

24 Apr 2009

Trends


The trend is towards higher speeds, of course. Offices have faster computers, faster Internet and more demanding applications. But does this translate into a need for Cat6 cable?

Cat 5e cable is an enhanced version of Cat 5 that adds specifications for far end crosstalk. Cat 5e cable does not enable longer cable distances for Ethernet networks: cables are still limited to a maximum of 100m (328 ft) in length. Each Cat 5e cable can carry up to 100mb/sec of data.

Cat 6 cable carries 1gb/sec of data and therefore has 10 times the data capacity of Cat 5e.

The Decision Considerations


Cat 6 will not make your Internet speeds faster. Even at fiber speeds, the Internet still only runs at a fraction of Cat 5 speeds. Cat 6 will also not make VOIP phones were better because VOIP uses only 60-90k per phone line. So, VOIP is a very unlikely reason for using Cat6 cabling

The only reason for using Cat 6 is because you are pushing a lot of data over your cable. This is true when you are running applications off of a server as in the case of a virtual PC environment where applications do not reside on the local desktop system. It is also true when you have applications that have very large data files as in CAD/CAM and other demanding graphic design systems.

A secondary, yet important, consideration is cost. Cat 6 cable is twice as expensive as Cat 5e and it also r

equires Cat 6 jacks, inserts, patch panels and switches. This can add considerably to the overall cost of a project. Any Cat 5 component will slow the connection down to 100mb.
