5. Conclusions¶
5.1 Link comparison : Optical link vs Coaxial Cable for 30 m link length (like in a home)¶
| Parameter | Coaxial Cable | Optical Link |
RF Gain @ 950 MHz [dB] | -3.6 | +0.5 |
|---|---|---|---|---|---|
| RF Gain @ 2150 MHz [dB] | -5.6 | +3.0 | |||
| Noise Figure @ 950 MHz [dB] | +3.6 | +30 | |||
| Noise Figure @ 2150 MHz | +5.6 | +33 | |||
| IIP3 [dBm] | +50 | +10 | |||
| SFDR [dB/Hz2/3] | +145 | +102 | |||
| LNB remote supply | Yes | No, supply close to antenna for OTX required | |||
| Current Consumption [mA] | 0 | 700 mA / 12 V | |||
| LNB telecommand | No | No | |||
| Bidirectional link | Yes | Yes, but with additional hardware | |||
| Cost | Low | High |
