Broad-band external modulation fiber-optic links for antenna-remoting applications

We present a 6-12 GHz external modulation fiber-optic link with a spurious-free dynamic range (SFDR) of 65.5 dB MHz. This result validates an analytical model for external modulation link performance which we have updated from a previously published model to account for the use of a traveling-wave external modulator. Using the revised model, we compare the expected performance of two different link architectures.
