2.3 Main Parameters

This part lists the main specifications and highlights the main parameters to compare an optical link with a coaxial cable

2.3.1 Optical link

The optical link consists of :
  • Optical transmitter OTX1910 from the manufacturer lynx-technik : it modulates the intensity of the optical 1320 nm wavelength with the RF input signal ;
  • Monomode fiber 9/125 OS2 (to avoid dispersion effect) to optical signal on a distance up to 10 kilometers ;
  • Optical Receiver ORX1900 from the manufacturer lynx-technik : it detects optical wavelength intensity modulation and outputs the RF modulating signal.

Overall Optical link with fiber length of 1 m

Lynx-technik technical provided us more technical specifications about the optical link.

However, they do have any phase noise measurements.

Optical link with fiber length of 1 m min typ max Unit comments
Noise Figure - - 31 dB
Carrier to Noise Ratio 55 - - dB Pin=-13 dBm, Fiber=1 m
SFDR 102 - - dB/Hz2/3 Pin=-13 dBm, IM3=50 dBc
IIP3 12 - - dBm Pin=-13 dBm, IM3=50 dBc

2.3.2 Coaxial cable

The optical link is a replacement of a coaxial cable EN50117-6 11PATC/PH 1.7/6.9 Class A 3GHz (B93) 17/13 139m.

COAXIAL CABLE min typ max Unit comments
RF Loss @ 20°C - 0.9 - dB/100m 5 MHz
- 2.7 - 50 MHz
- 3.8 - 100 MHz
- 5.4 - 200 MHz
- 7.7 - 400 MHz
- 11 - 800 MHz
- 11.5 - 862 MHz
- 12.1 - 950 MHz
- 14.6 - 1350 MHz
- 16.7 - 1750 MHz
- 18.7 - 2150 MHz
- 22.3 - 3000 MHz
IIP3 50 - - dBm Estimation

IIP3 is only an estimation to be compared with optical link : this value is deemed quite conservative due to the fact the cable is a passive component.
