Optical receiver ARCOTEL series GA8025(OR)
- More products
The optical receiver ARCOTEL GA8025(OR) is intended for work in hybrid fiber-coaxial networks of cable television with deep optics penetration. Mainly its FTTH and FTTB networks .The receiver converts the optical amplitude-modulated signal into the radio-frequency (RF) wideband signal of TV range and provides further signal amplification for its distribution through the coaxial network.
Advantages:
- Optical receiver in a compact case;
- Wide range of input levels of the optical signal;
- Display of optical input level;
- High output RF signal level at low input optical signal;
- The output stage is implemented by the scheme Push-Pull;
- Low power consumption;
- Protection against overvoltage output.
