- RF output level and slope are adjustable. Output port 1-2 are available, tap/splitt are available.
- Reserve international standard network interface, easy to field upgrade
- Optical AGC function,the output level changed within ±0.5dB, while input power changed at +1dBm~-6dBm
Brief
TFR7800W 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.
TFR7800W Optical receiver power range is at 1~ -6dBm. When receiver input power at 0dBm, and dual outputs, each RF output level up to 104dBuV; single output level up to 108dBuV; 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.
