TFR7800S Optical Receiver

Summarize TFR7800S optical receiver can be used for HFC network, digital network and telecommunication network. It especially suitable for fiber extension to the floor, the output directly covers the user’s HFC fiber-optic network. Adopt high-performance, high-efficiency optical detector, RF input, output stage adopt high-quality GaAs amplification, high reliability, low power, low noise and extremely excellent performance price ratio. TFR7800S receive optical power range is +1dBm -9dBm,optical AGC range is +1 -6dBm,when the receive power range is -6dBm,each RF output port dual-port output power level up to 96dBuV; signal-port output up to 100dBuV;when the receive optical power is -6dBm, C/N>45dB,MER>35dB; The high-performance conversion circuit enable to turn into +24V,+5V DC power to supply the optical receiver internal device. Network management transponder fully complies with the national standard, SCTE HMS and IEC. Be able to monitor the real-time status, performance parameters of the optical node remotely, manage the network configuration remotely.
