We describe a single-carrier, polarisation-multiplexed 46 Gbaud 64 QAM coherent transmission. Using an LD-based injection-locked local oscillator for homodyne detection, we transmitted 552-Gbit/s data over 160 km with a bit-error rate of 6×10-4. The potential spectral efficiency reached 9.2 bit/s/Hz.
