适用于中距离传输,通常1290x1200信号可传输50米,低分辨率信号会传输更长一些。DVI双绞线传输器包括一个发射器和一个接收器,有的厂家产品需要两端供电,有的厂
家产品只需一端供电。传输DVI信号的同时还需要一个DDC信号,用以来识别分辨率等信号,所以一般用2根双绞线连接发射器和接收器,分别传输DVI信号和DDC信号。尽管DVI双绞线传输器有一定的造价,但是由于双绞线成本低,而且容易布线,传输距离相对较远,降低了平均成本,所以这种方式成为一种能够普遍接受的方式。优点:成本平均、布线方便。缺点:在电脑和显示器之间增加了接收器和发射器两台设备,安装相对复杂。
4、使用光缆传输设备适用于长距离传输,远可达500米。
这种方式和种不同,它使用普通的光缆,LC多模式或者ST光缆,而种方式使用的是特殊电缆。它的工作方式基本上和双绞线传输器相同,使用一对发射器和接收器,用光缆传DVI信号,用1根双绞线传DDC信号。优点:传输距离长 缺点:光缆相对比较脆,容易折断,布线时要多注意。
5、将2条超长DVI铜缆进行串联(远可达80米)
亚博足彩这种方式基本能够满足当前工程上所需的室内传输距离。选择这种方式有一个关键点,就是要求DVI线缆的质量一定要过硬,比如将和睿高清的2条40米穿管型DVI线或者2条40米工程级HDMI线串联起来,可达80米无损传输。优点:成本适中,稳定性强  缺点:长可传输80米,距离有限。
