Abstract :
It is found experimentally that differential-phase-shift-keying with balanced detection offers /spl sim/6 dB higher tolerance to in-band coherent crosstalk than on-off-keying in optical signal-to-noise-ratio limited systems. An explanation of its high crosstalk tolerance is also provided.
