ACR1000A-R2   延长器  用来延长信号的器件

ACR1000A-R2 延长器是用来延长信号的器件，通常用于长距离直连线材无法满足传输要求的情况。一般来说，延长器是为了确保信号长距离无衰减的传输而设计的，因此多是有源的。

ACR1000A-R2 延长器一般分为发送端和接收端，发送端负责完成信号获取和压缩的作用，接收端负责完成信号的解码和端口分配。为了使信号能够达到最好的质量，在独立供电的设备端一般会有增益或者其它参数独立调节的旋钮。发送和接受端之间可以是同轴电缆，双绞线（网线），甚至是光纤等等，根据设备应用而不同。

根据功能的不同，ACR1000A-R2延长器可以分为：

HDMI双绞线传输器：由一个发送器与一个接收器所组成，中间可使用要求符合HDMI 1.2、DVI 1.0规范。

VGA延长器、DVI延长器：用于计算机信号的长距离无衰减的传输。

BNC或RCA视频延长器：用于视频或音频的长距离传输。

USB延长器：用于延长USB控制，远端的USB设备的接入。

KVM延长器：可以说是传统延长器的升级版，在延长音频和视频信号的基础上加上了USB延长的功能。在电脑主机上使用KVM延长器就能在百米、千米外使用1套键盘鼠标和1台显示器控制电脑看电影、聊天、打字、办公等。

此外，从使用的介质上，延长器可以分为光纤延长器、网线延长器和无线延长器等。KVM延长器从使用的介质也可以分为：KVM光纤延长器和KVM网线延长器。

ACR1000A-R2   延长器  用来延长信号的器件

The ACR1000A-R2 extender is a device used to extend the signal, usually used for long distance directly connected wire can not meet the transmission requirements. In general, the extender is designed to ensure that the signal is transmitted over long distances without attenuation, so it is mostly active.

ACR1000A-R2 extender is generally divided into the sending end and the receiving end, the sending end is responsible for completing the role of signal acquisition and compression, and the receiving end is responsible for the decoding of the signal and port allocation. In order to achieve the best quality of the signal, there are generally knobs for independent adjustment of gain or other parameters at the end of the independently powered equipment. Between the sending and receiving end can be coaxial cable, twisted pair (network cable), even optical fiber, etc., depending on the device application.

Depending on the function, ACR1000A-R2 extenders can be divided into:

HDMI twisted pair transmitter: consists of a transmitter and a receiver, the middle can be used in accordance with HDMI 1.2, DVI 1.0 specifications.

VGA extender, DVI extender: used for long-distance unattenuated transmission of computer signals.

BNC or RCA video extender: Used for long-distance transmission of video or audio.

USB extender: Used to extend USB control, remote USB device access.

KVM extender: Can be said to be an upgraded version of the traditional extender, extending the audio and video signal on the basis of USB extension function. Using the KVM extender on the computer host, you can use a keyboard and mouse and a monitor to control the computer from 100 meters or kilometers away to watch movies, chat, type, and work.

In addition, from the medium used, the extender can be divided into optical fiber extender, network cable extender and wireless extender. KVM extenders can be divided into optical fiber extenders and network cable extenders based on the media used.
