Broadband Video over Category 6 DTP Cabling

摘要

In this paper, we will provide information on the application of broadband video over high performance Category 6 UTP cabling. We will describe the implementation of a broadband video distribution system over twisted pair cabling and some applications where it might be used. We will look at the advantages of running broadband video transmission over a parallel network (RF highway) compared to running video over the corporate LAN highway. We have recently completed a series of comprehensive tests to demonstrate the technical feasibility of running broadband video (CATV) over a high-end Category 6 cabling system up to a frequency of 550 MHz (78 channels of NTSC video). This paper will show the results of these tests in a real-time environment including signal level measurements, alien noise measurements, and the effect of simultaneous LAN and video transmission in the same cable.
