Comparing stochastic simulations and experimental measurements, we study the quantum dynamics of polarisation squeezing in optical fibres. Squeezing of -6.8 dB is measured, with Raman effects limiting squeezing for higher pulse energies and longer fibres. Depolarising GAWBS phase-noise adversely affects squeezing at low pulse energies. Third-order dispersion is also accounted for in the simulations, and this has an effect on pulses with more than the soliton energy. We theoretically determine the optimal pulse energy and fibre length for the best squeezing.
