The transmission of a 40 Gbit/s channel over 186.6 km of installed standard fiber with mid-span spectral inversion for polarization mode dispersion (PMD) compensation using phase conjugation by four-wave mixing in an semiconductor optical amplifier was investigated. Error-free operation was obtained with good system stability despite the use of a polarization sensitive mid-span spectral inversion (MSSI) configuration. The results indicated the viability of upgrading existing fiber links to higher bit-rates on a single wavelength channel using MSSI and optical time division multiplexing.
