TFR7800J Indoor Optical Receiver

Overview    The TFR7800J indoor optical receiver is designed to transmit the cable TV signal. Simple 220V, 50Hz or DC48V power supply, 2 RF output F connector OUT1, OUT2. Features         ● The output adopts the import module, which improves the C/N and the nonlinear distortion characteristics, and also reduces the power consumption of the whole machine.
        ● Strict reliability test, MTBF is more than 100 thousand hours;
        ● AGC for forward optical receiving, the range of output level is within + 1dB when optical power is -6dBm to +2dBm.
        ● RF output level and slope adjustment can be set through the LCD screen.
        ● Splitter / distributive output optional;
        ● LCD display control and RJ45 network management status monitoring, support SNMP network management, can be monitored by local computer. Technical Specifications
