描述
HDMI（高清晰度多媒体接口）近来在视频和音频传输系统的应用中日益普及。然而，鉴于电气性能的极端，传统的铜线电缆对信号传输距离和信号质量施加了限制。实际上，与传统的铜线电缆相比，光纤具有低色散，反而具有较长的信号传输距离和更好的信号传输质量。 DVI / HDMI扩展器使用2芯光纤，内部没有任何铜线，其中射频干扰现象被排除在外，显示出高性能，良好的信号质量以及低成本的优势。
高性能 - KHX-2240系列是一款高性能4K HDMI KVM光纤扩展器，可使用2芯光纤在极远距离内传输高分辨率DVI / HDMI信号。此扩展器支持HDMI v1.4信号，分辨率高达4K（4096x2160 / 30p），电缆距离可达300米。
光纤扩展 - 扩展器组由光发射模块组成，可将DVI / HDMI信号转换为光脉冲，通过2芯光纤进行传输。光接收器模块将光脉冲转换回DVI / HDMI信号，以便在监视器或投影仪上显示。
尖端光学 - 大多数单纤维光学延伸器通过多个光波长传输信号，这可能会在长电缆运行中受到色散影响。为了避免这个问题，该扩展器采用了尖端的高速SerDes，将DVI / HDMI信号通道组合成单个未压缩的10.3Gbps位流。这使得能够在单个光学波长上进行信号的光传输，这提供了信号保真度，稳定性和无瑕疵的图像质量，而与电缆长度无关。这些功能使KHX-2240系列是需要在极远距离上传输高分辨率DVI / HDMI信号的系统设计人员和集成商的理想的未来选择。

Description
HDMI (High-Definition Multimedia Interface) recently has become increasingly popular in the application of video and audio transmission system. In view of the extreme of electrical performances, however, the traditional copper wire cable imposes limits on signal transmission distance and signal quality. In reality, optical fiber is of low dispersion, which in turn has the strength of longer signal transmission distance and better signal transmission quality in comparison to the traditional copper wire cable. DVI/HDMI extender uses 2 cores fiber without any copper wire inside, where radio frequency interference phenomenon is literally ruled out, which shows the advantage of high performance and good signal quality as well as low cost.
High Performance - The KHX-2240 series is a high performance 4K HDMI KVM Fiber Optic Extender that transmits high resolution DVI / HDMI signals over extreme distances using 2 cores fiber. This extender supports HDMI v1.4 signals with resolutions up to 4K (4096x2160 / 30p) over cable distances up to 300m.
Fiber Optic Extension - The extender set consists of an optical transmitter module that converts the DVI / HDMI signals into light pulses for transmission over a 2 cores fiber. An optical receiver module converts the light pulses back to a DVI / HDMI signal for display on a monitor or projector.
Cutting-Edge Optics - Most single-fiber optical extenders transmit signals over multiple optical wavelengths, which can suffer from chromatic dispersion over long cable runs. To avoid this issue, this extender employs a cutting-edge, high-speed SerDes that combines the DVI / HDMI signal channels into a single uncompressed 10.3Gbps bit stream. This enables the optical transmission of the signal over a single optical wavelength, which provides increased signal fidelity, stability and flawless image quality, regardless of cable length. These features make the KHX-2240 series the ideal future-proof choice for systems designers and integrators who need to transmit high resolution DVI / HDMI signals over extreme distances.
