Abstract :
A 16 × 112 Gb/s field transmission trial was successfully performed over legacy fiber infrastructure of Deutsche Telekom comprising partially high polarization mode dispersion (PMD) values of 8 ps. Using a commercial PMD compensator, transmission over high PMD with negligible penalty was achieved. Enabled by the maturity of 43 Gb/s components, a 112 Gb/s nonreturn to zero (NRZ) differential quadrature phase-shift keying modulation format for dense wavelength division multiplexing transmissions with good system margins of 5 dB over 450 km metro distances (3 dB over 764 km) was demonstrated. By using high baud rate of 56 Gbd, penalty-free transmission is performed when copropagating with either 10.7 Gb/s NRZ or 43 Gb/s phase-shaped binary transmission signal channels.
