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¶

• Optical transmitter OTX1910 : 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 : it detects optical wavelength intensity modulation and outputs the RF modulating signal.
