TFR7800 FTTB Optical Receiver

Overview    TFR7800 FTTB optical receiver is one-way optical receiver with one or two output port. It can be used in the CATV network, digital network and telecom network, especially for fiber to building application.
   TFR7800 optical receiver ‘s receiving optical power range is -10 ~ +3dBm. AGC range is -10～+2dBm or -8～+2dBm or -6～+2dBm optional. For two output ports product, each RF output level can be up to 98dBuV, 102dBuV, 106dBuV respectively. For single output port product, the output level is up to 102dBuV, 106dBuV, 110dBuV respectively. When receiving at -6dBm, CNR is larger than 47dB.
   AC220V is converted into DC12V into the optical receiver via an external high quality switch power adapter. Features         ● Working bandwidth: 47-1000MHz
        ● Comply with SNMP standard
        ● Support remote and local setting for the management of the receiver
        ● Support Web management
        ● Perfect surge suppression circuitry, improved the anti-lightning strike and the prevention of lightning surge shocks
        ● AGC range -10～+2dBm or -8～+2dBm or -6～+2dBm optional, receiving optical power range -10~+3dBm
        ● Input stage adopt imported low-noise GaAs amplifier, output stage adopt imported CATV high-pertableance, high reliability GaAs power multiplier module, greatly improved the C/N and non-linear distortion characteristics while significantly reducing the power consumption which is less than 7W
        ● Rigorous reliability test, MTBF ＞100,000 hours
        ● High quality photodetectors with response degree greater than 0.9A/W
        ● Supporting real-time display of OP,RF,ATT,EQ and working status and setting of ATT and EQ. Technical Specifications
