 Feature

l         Perfect surge suppression circuit, improved the anti-thunder stroke and surge impact prevention ability

l         The input stage adopt imported low noise GaAs amplifier, the output stage adopt imported CATV GaAs high performance chip, improved C/N and the non-line distortion characteristic greatly, simultaneously reduced the power consumption

l         Strict reliability test, MTBF is longer than 100,000 hours

l         Excellent optic detector: responsibility > 0.9 A/W, light alarm instructions when input power too low

l         RF output level and slope are adjustable. Output port 1-2 are available, tap/splitt are available.

l         Reserve international standard network interface, easy to field upgrade

l        Optical AGC function,the output level changed within ±0.5dB, while input power changed at +1dBm~-6dBm

 

Brief 

TFR7800X optical receiver can be used for CATV network, digital network and telecom network, especially suitable for optical fiber extends to the building, connect to subscriber’s home directly.

TFR7800X Optical receiver power range is at 1~ -6dBm. When receiver input power at 0dBm, and dual outputs, each RF output level up to 100dBuV; single output level up to 104dBuV; when optical receiver power at -5dBm, C/N > 49dB.

~220V power-supply modes are available, the high-performance transforms circuit become + 24V, + 5V straight to optical receiver internal devices.
