High density solution for the return path channel optical reception. Provides a wide input optical margin (from -16dBm to 1 dBm), to adapt to high dispersion networks on link losses. A low noise figure pre-amplifier plus a high linearity power amplifier stage guarantee the best reception conditions. The embedded AGC in the RF segment provides an estable output level in the whole operating margin. If needed, the AGC can be disabled just to make an adjustment in the output level from 0 to 14 dB.
