2 Microwave Fiber Optic (F/O) Link Analysis Microwave (linear) F/O Links used for point-to-point communications Antenna remoting Sensors Radio-over-Fiber. We present a new method for quickly determining the system impact of a F/O Link GAIN NOISE LINEARITY. We demonstrate a linearization method for improved F/O Link linearity

4 Brief Overview: Fiber and Optical Medium Propagation Loss in Optical Medium Fiber is (almost) lossless, compared to coax 9 µm single-mode ~.5 db/km at 55 or.4 at Connectors, splices, switches, splitters add loss Chromatic Dispersion Upper and Lower sidebands arrive at different times Generally not a concern for < km and < 4 GHz Fiber Nonlinearities Items to be aware of, but generally not a concern for single-wavelength with < mw optical power: Stimulated Brillouin Scattering (SBS) Backscattering effect leading to high noise and nonlinear power transfer Stimulated Raman Scattering (SRS) Can lead to degenerative optical gain when optical power is very high Four-Wave Mixing (FWM) and Cross-Phase Modulation (XPM) Intermodulation distortion and cross-talk in WDM systems (multiple optical wavelengths) Self-Phase Modulation (SPM) Leads to nonlinear group delay Lower Sideband Optical Carrier Upper Sideband Dispersion causes phase delay between detected optical (AM) sidebands 4
5 System Parameters using DiLink End-to-End Gain DiLink gain is typically or 5 db Fully temperature-compensated, referenced to db OL End-to-End gain is lower by twice the optical loss Noise Three primary Sources: Laser (RIN), Shot, Thermal Output noise level depends on optical power at the receiver Third-order Linearity IP is intersection of st and rd order transfer lines Contributors: Laser, Receiver, RF Amplifiers Transmitter: Fixed IP Receiver: IP decreases with higher optical receive power (photoreceiver and amps driven harder) Overall: depends on optical loss Noise Density (dbm/hz) Output Power (dbm) thermal Output Noise Density Total Noise shot Received Optical Power (dbm) Output noise density is the result of primary sources: RIN, Shot, Thermal Linear Photonics, LLC. Non-linearized Pout vs Pin - 8 GHz Input Power (dbm) Fundamental Pout rd Order Pout IP Third-order Intercept is the (imaginary) intersection of st and rd order output RIN IP = 8 dbm By By defining the the link link properly, the the primary system parameters depend only only on on optical loss loss 5
