We report a method to determine propagation delays of optical 10 Gb/s data traveling through a 75 km long amplified fiber link with an uncertainty of 4 ps. The one-way propagation delay is determined by two-way exchange and cross correlation of short

We demonstrate transmission of trellis-coded-modulated-12-spatial-and-polarization modes over 40km 6-LP-mode fiber with low differential mode group delay. By employing 8-PSK trellis coded modulation, an OSNR gain of 1.8dB is observed in comparison to
