Technical Specifications CFO471 SM uni-directional
Four channel video link High performance uncompressed real time digital video transmission e CFO First Mile series provides high quality reliable transmission of video, audio, data and contact closure information for CCTV applications such as security and surveillance
gmt
Vx4 Dx3 Ax2 C x1C M New CFO471 video links are basic building blocks for multi-channel video transmission system providing unidirectional transmission of 4 zerodelay video channels together with unidirectional audio, data and contact closure channels over one 1310 nm singlemode fibre.
Video Networks
Evolving from the CFO161/461/861 series, the new generation CFO471 video transmitters and receivers bring the CFO First Mile into an entirely new era of modern fibre optic transmission. In addition to enhanced 10 bit video, dual audio capacity and contact closure channel are available to same transmission direction as video.
CFO471 units are fully compatible with CFO platform installation mechanics. Standard CSR series racks and CMA series module adapters are available for easy installations. As with all CFO platform products these specific models do meet all typical EMC as well as other environmental and manufacturing related requirements.
