Summarize

TFR7800Nc 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.

TFR7800Na input receive optical power range is +2dBm~-8dBm,optical AGC range is +2~-8dBm,when the receive power range is 0dBm,each RF output level is up to 108dBuV for dual outlets;each RF output level is up to 112dBuV for single outlet;when the receive optical power is -6dBm,C/N>45dB;

~220V or ~60V power supply optional,the high-performance conversion circuit enable to turn them into +24V,+5V DC power to supply the optical receiver internal device.
