 The Product Summary

AOT digital and non-condensing Ring Net digital OFE is fiber equipment that uses digital and not-compression technique and WDM technique，through one core/two core fiber,form single/double fibers or cascade net，Simultaneous transmission multipath video and data signal；and control can be realized to the preceding end video camera。
 The roduct characteristic 
●Provide 2 direction optical fiber circuit interfaces，can form rig net or cascade net.
●The system can collocate and exchanged the video signal，at the same time also can collocate data signal；
●Using the modularization structure , the video data module that every Site can be according to real corresponding quantity of requirement disposition is disposed the nimble convenience .
●Video data module supply hot plug，each video data module all have 1load video/data or multiplexing。
●Data supply RS-422 and RS-485(2/4lines)data communications format，switch。
●The reliability is high to the industry level design
