How to use passive 10Mbps EOC converter?
R&D team of EnConn has developed an unique technique to achieve 10Mbps/ full duplex transmission for EnConn’s EOC-IN-B.
Ethernet over coax (EOC) converter can transfer Ethernet signal from
copper cable to coaxial cable. This technique can allow IP camera
industry to re-use existed coaxial cable as the transmission media and
extend the transmission distance larger than
However, there are some limitations or extra setting needed to be noticed. Most of 10Mpbs products in the market only have half duplex capability. If you want to send control signals to IP camera while IP camera transmitting digital video, the video stream will be interrupted by the control signals for a while. Of course, the users might not be aware of this if the 10Mbps bandwidth is not exhausted. The R&D team of EnConn has noticed this limitation and developed an unique technique to achieve
full duplex transmission for EnConn’s EOC-IN-B.
EOC-IN-B can allow users to have 20Mpbs throughput bidirectional instead of 10Mpbs throughput of other similar products. For high quality HD video, 10Mpbs is not enough. However, for recording capacity consideration and other specific usages, 8Mpbs has been accepted by many installers. Passive EOC converter has necessity of manual 10Mpbs setting. This means that you need to set NVR, Ethernet switch or IP camera to use forced 10Mpbs link. If you don’t set it manually, auto negotiation protocol can not set 10Mpbs and make the link failed to communicate. EnConn has rich experience to help users to overcome this setting issue. 10Mpbs switch has been provided by EnConn to users in order to save the setting trouble. Another drawback of current passive EOC is the loop back return issue. When the link is unplugged without impedance matching, it will cause the connected switch crashed. EnConn has also invented a unique technique to prevent this happen and has put this technique into eco-net series products. From cost point of view, 10Mpbs passive EOC converter is a good choice. However, you need to accept some troubles and 10Mpbs bandwidth limitation.
