It was recognized that the delay skew (delivery time) between the pairs was a key factor in receiving component video signals so Belden now produces three styles of low-skew UTP cable. We manufacture a Category 6 data cables with a maximum delay skew of 10 nanoseconds in 100 meters. (Compare this to the 45 nanosecond skew of generic Cat 5e or 6.) We also make a Category 5e with 9 nanosecond of skew. It should be noted that either of these cables can support the normal 100BASE-T or 1GBASE-T data networks, and also be used for non-data applications such as RGB or VGA. We are approaching a point where one cable could do almost anything in a given commercial installation.
If those delay skew numbers are still too much, we also designed Belden NanoSkew®, where the maximum skew is just over 2 nanoseconds in 100 meters. We accomplish this by twisting all four pairs identically. While this gives unrivaled skew performance for RGB, VGA and related signals, the crosstalk of this cable makes it unuseable as a data cable. This cable looks and connects like a data cable but it is video only.
