This coax cable is the first designed specifically for 4k single link uhd video cable in the broadcast market for 12g sdi signal transmission. At the same time it has also promoted an era of a new digitized.

Serial digital interface sdi is a family of digital video interfaces first standardized by smpte the society of motion picture and television engineers in 1989. In the us a roll of belden 1505a hd sdi cable is about 450 for a 1000 roll 384 meters. To demonstrate v73263 is a superior solution to rg179 in 3g sdi applications this article will directly compare the two cables against the four main factors commonly considered in cable choice decisions. For example itu r bt 656 and smpte 259m define digital video interfaces used for broadcast grade video a related standard known as high definition serial digital interface hd sdi is standardized in smpte 292m.

Maximum length 30db loss at half the clock frequency. Reference sdi maximum cable distance chart. Interfaces such as connectors and patching may alter the overall end to end parameters as the cable. All cable is not created equal.

Maximum length 30 db loss at 1 2 the clock frequency. Loss shielding ease of termination and cable connector impedance. Maximum length 30 db loss at 1 2 the clock frequency. Per 3g sdi standards most receivers require 20 db of loss at 1 5.

Alternates to belden 1505a are products like gepco vpm2000 or canare l 4cfb. Maximum length 20db loss at half the clock frequency. This provides a. This provides a method of defining the maximum calculated length of cable for satisfactory signal transmission 1.

If you are not using double shielded cable rated at 75 ohms it s not going to work. The above graphs do not represent the exact cable length possible. Sdi serial digital interface widely used in sdi encoders sdi converters and other equipment which has been applied to radio and television fields security monitoring. Maximum length 20 db loss at 1 2 the clock frequency.

The maximum length of cable depends on a number of factors. It is a digital format that can be used for both sd and hd signals. Because of this the exact maximum cable length possible will vary. Belden s 4794r coax for 4k uhdtv 12g sdi offers superior performance easier installation and reduced weight and space compared to quad or dual link.
