What is the difference between channel and permanent tests? And what is a network cable headroom?
After cabling a network, the network should be tested with a device to ensure that the cabling is correct and without defects and that the network is working properly and that the cables are not disconnected. There are many testers available in the market and the best tester in the world is known as the Flock Tester.
This tester provides complete information on the quality of cabling, network speed, cable diameter, exact location of the cable, etc. indicate.
Channel Flux Test: A simpler example of a network cable test is that the two ends of the network cable are first connected to the device using a cord patch and then the flux test is taken.
Permanent Flock Test: A more complete example of the previous test, this time we keystone the cable and connect the cable to the device by permanent modules that belong to the Flock Tester and start doing the Flock Test.
A cable that passes the Permanent Flux Test will definitely pass the Channel Flux Test. However, a cable that passes the Permanent Flux Test may not pass the Permanent Flux Test.
Usually, Nexus and Legrand network cables are guaranteed to pass this test.
What is a network cable headroom?
is a term often used in the network cable manufacturing industry to describe the performance of a cabling system. This value is measured in decibel units. In fact, the cable headroom is a network term that depends directly on the physical parameters of the cable. And this parameter is known by network experts as a determining value for the quality degree of the network cable.
What is Headroom Test Flock Cable Network?
In the flow test, we encounter two words, NEXT and Headroom, which mean the following:
Next is the most important noise factor in a network cable and is measured in decibels (dB). Increasing the next values in the flow test charts is directly related to the high quality of the cable.
This parameter, which is based on the crosstalk measured in the network cable, displays the same parameter as the next. Headroom is the smallest amount of Next calculation. Cables that pass the permanent test with a headroom above 5 have a good headroom.
