3G/HD-SDI视频光端机


3G/HD-SDI-T/R

 

产品简介:

      高清多媒体监控应用系统中,往往需要把高清非压缩的数字音视频信号源远距离传输。但使用普通的电缆长距离传输时,总会出现输出信号差,容易受干扰等现象。同时传输距离短,不能满足多媒体信息发布等场合长距离传输的要求,使用3G/HD-SDI-T/R光端机传输3G/HD-SDI信号,完全解决了此类问题,传输距离1米-20公里。同时,光端机传输具有衰减小、频带宽、抗干扰性强、安全性能高、体积小、重量轻等优点,所以在长距离传输和特殊环境等方面具有无法比拟的优势。此外, 3G/HD-SDI设备在多媒体系统中应用,即节省施工成本及走线的复杂性,又能保证高品质的目标为可能。

      3G/HD-SDI-T是光发送器,3G/HD-SDI- R是光接收器,二个设备配合使用,可实现经3G/HD-SDII-T光发送器把3G/HD-SDI视频信号经光缆长距离发送给3G/HD-SDI- R光接收器,在不经过对信号进行任何压缩处理后,高保真输出“原装”的视频信号。
