RF 1200 Switch

Overview    RF1200 RF switch module with two path RF signal input ,one path RF signal output are widely used in the 1550 nm, 1310 nm ring-network system.Users can set the switching threshold.with two path RF input signal detection and judgment, if radio frequency signal level is lower than or exceeds the threshold, the switch will set to switch on its own.
   In the case of two way RF signals are normal,products support switching manually RF channel , and switching on the front panel or remote network management forcefully. At the same time ,remote network management provides a real-time monitoring. Features         ● Indoor 1U structure, Bandwidth:5 ~ 1000 MHZ
        ● A and B channels can be switched automatically and manually, which improves the reliability of the network
        ● Users can set switch threshold
        ● Excellent in-band flatness and reflection loss
        ● Adopting aluminum case, drawing surface oxidation, high shielding factor
        ● Open network management meets the national NM standard, the SCTE HMS NM standards and IEC NM standards Technical Specifications
