תיאור
This cable is designed for transmitting both digital and analogue video signals and is used for both rack applications and installations. The polished solid copper core has a diameter of 0.60 mm and is enclosed in a physically foamed PE dielectric medium that ensures signal transmission with no return loss and ultra-low attenuation. Typical transmission distances under SMPTE standards are 255 metres for SDI video signals, 65 metres for 1.5 Gb/s HD-SDI signals and 47 metres for 3 Gb/s signals. However, in practice longer distances may well be possible depending on the devices used. Effective protection against electromagnetic interference is offered by double shielding comprising an AL double composite layer and an ultradensely woven copper shield providing over 92 per cent screening. The outer jacket is of FRNC material, which is flame-retardant and completely halogen-free – a vital advantage for installations.
