Transferring data over your network relies on ‘link performance’, i.e. the cable/component’s ability to transfer a signal while retaining its original information content. A minimum level of performance is required, and this is measured during testing by the amount of ‘headroom’ that is left.
Headroom is affected first by the quality of components used, second, by cable length, third, by cable handling and fourth, by termination quality.
The better the quality of materials, the shorter the cable length runs, the better the cable handling during installation and the better the termination all equal a larger link headroom.
You should be aiming for as large as headroom as possible. the larger the headroom, the more allowance your links have for being able to transmit data quickly and accurately and the more able they are to function when they come into contact with environmental issues, crosstalk or noise.
With all new installs, any good installer will test and provide you with your headroom results (also your way of verifying the links and the install) With our Analysers we can also test older networks. Call us for more information.
