Coaxial Video Cables
Coaxial video cables made by bda connectivity are characterized by tightly limited characteristic impedances of 75 Ω +/-1%. Without this limitation, signal reflections would lead to a considerable deterioration of the picture quality in a television studio where a large number of video cables are coupled together.
Of course, applications in surveillance technology also benefit from these properties: the excellent image quality of the display enables crimes and perpetrators to be easily identified if necessary.
We also offer these cables with halogen-free and flame retardant equipment (FRNC).
The SDI interface design allows defined limits for line attenuation and cable return loss. Both values are additionally dependent on the cable length. This results in the following maximum lengths for our cables (rounded to the nearest meter):
|Standard||Name||Short Name||Bit Rate||Video formats (examples)||Video 0,6/2,8C||Video 1,0/4,8C|
|Max. Länge / Max. Length (m)|
|SMPTE 292M||HDTV||HD-SDI||1,485 Gbit/s||720p, 1080i (HDTV)||68||107|
|SMPTE 344M||Component Video Widescreen||ED-SDI||540 Mbit/s||480p, 576p||174||280|
