随着城市建设、道路交通和网络工程的不断深化发展,要在日趋复杂城市布局中和地形多样的高速公路和隧道等等场所中,重新埋设光纤是不太现实的,因为工程量巨大,周期长,资金投入大。如何用尽可能少的光纤传输大量分散分布的视频,成了监控系统的传输方案不可避免需要考虑的问题,特别是在关键区域的智能监控系统中,更需要一种组网灵活、可靠性高、节省光纤、维护方便、高性价比的传输设备。
With the continuous deepening of urban construction, road traffic and network engineering, it is impractical to re-embed optical fiber in increasingly complicated urban layouts and diverse terrain such as expressways and tunnels. Due to the huge amount of engineering, Long, capital investment. How to transmit a large amount of distributed video with a minimum number of optical fibers has become an inevitable problem that needs to be considered in monitoring the transmission scheme of the system. In particular, in an intelligent monitoring system in a key area, a more flexible networking and high reliability , Save fiber, easy maintenance, cost-effective transmission equipment.
