Abstract :
We investigated analog rf crosstalk levels in a 25 km, wavelength-division multiplexed, Er-amplified fiber optic link for both a) amplitude modulation with direct photodetection and b) phase modulation with differential interferometric demodulation and photodetection. Experimental results are presented for optical channel spacing in the range 50 GHz to 200 GHz.
