Selection of Cable
a.
Selection:
Most makes and versions of Cat 5/5e/6 cables will work with DVI-C5-S
Transmitter and DVI-C5-R Transceivers. However, since the quality and characteristics of Cat
5/5e/6 cables varies it has been found that some perform better than others. The major
factor influencing the transmitting distance is the skew property of the cables. Skew
represents the difference in propagation delay between the fastest and slowest set of wire
pairs. A lower skew will mean a longer video transmitting distance.
b.
Skew Property:
A Cat 5/5e/6 cable with a skew lower than 15ns/100m should enable a
cascading length of < 80m (275 ft) at 800x600, <50m at 1024x768, and < 40m at
1280x1024.
Cat 5/5e/6 cable with a skew of lower than 15ns/100m should enable a cascading
length of:
< 80m (275ft) @ 800 x 600
< 50m (175ft) @ 1024 x 768
< 40m (150ft) @ 1280 x 1024
