| 3 | 4 | HAENNIG, Gerald | h2. 5.1 Link comparison : Optical link vs Coaxial Cable for 30 m link length (like in a home) |
| 4 | 4 | HAENNIG, Gerald | |
| 5 | 7 | HAENNIG, Gerald | In the following table, there is a comparison between coaxial cable to optical link. |
| 6 | 7 | HAENNIG, Gerald | |
| 7 | 5 | HAENNIG, Gerald | |_. Parameter|_. Coaxial Cable|_. Optical Link | |
| 8 | 5 | HAENNIG, Gerald | |RF Gain @ 950 MHz [dB]|-3.6 |+0.5| |
| 9 | 4 | HAENNIG, Gerald | |RF Gain @ 2150 MHz [dB]|-5.6|+3.0| |
| 10 | 4 | HAENNIG, Gerald | |Noise Figure @ 950 MHz [dB]|+3.6|+30| |
| 11 | 4 | HAENNIG, Gerald | |Noise Figure @ 2150 MHz|+5.6|+33| |
| 12 | 4 | HAENNIG, Gerald | |IIP3 [dBm]|+50 |+10| |
| 13 | 4 | HAENNIG, Gerald | |SFDR [dB/Hz2/3]|+145|+102| |
| 14 | 4 | HAENNIG, Gerald | |LNB remote supply|Yes|No, supply close to antenna for OTX required| |
| 15 | 4 | HAENNIG, Gerald | |Current Consumption [mA]|0|700 mA / 12 V| |
| 16 | 6 | HAENNIG, Gerald | |LNB telecommand|Yes|No| |
| 17 | 4 | HAENNIG, Gerald | |Bidirectional link|Yes|Yes, but with additional hardware| |
| 18 | 4 | HAENNIG, Gerald | |Cost|Low|High| |
| 19 | 7 | HAENNIG, Gerald | |
| 20 | 7 | HAENNIG, Gerald | For a distance of 30 m, optical link is not justified : performances and cost are not competitive with coaxial cable. |
