Summarize
TFR7800 FTTB optical receiver can be used for CATV network, digital network and telecommunication network. It especially suitable for the FTTx network which the fiber extended to the building, the output ports covered subscribers.
TFR7800 FTTB optical receiver input power range is -9dBm~+3dBm, optic AGC adjustment range is -8~+2dBm,among this range, every port is up to 102dBuV for the dual outlets.CNR> 47dB at -6dBm input.
AC220V power is converted to DC6.5v through the out-set power adapter to feed the receiver’s interior.
Features
l 47~1000MHz working bandwidth
l Completely comply with the national standard SNMP, support remote or local operation to optical receiver’s setting and management, support setting and management directly to Web page.
l Perfect surge suppression circuitry, improved the anti-lightning strike and the prevention of lightening surge shocks
l -8~+2dBm stable optic AGC function, input power range -9~+3dBm
l Adopt imported low noise, high performance GaAs chips, greatly improved C/N and non-line distortion while significantly reducing the power consumption, complete machine’s power consumption is less than 7W.
l Strict reliability testing, MTBF is more than 100 thousand hours.
l Adopt excellent detector, responsiveness is bigger than 0.9A/W.
l Real time display the status of input power(OP),output RF level(RF), ATT value(ATT), EQ value(EQ) by LED, and real time setting to ATT and EQ.
l Out-set high quality switching-power adapter which have 3C certification
