ABSTRACT
This paper proposes a hybrid technique of Polarization Division Multiplexing and Wavelength Division Multiplexing with NRZ modulation. This design consists of 16 wavelengths with 32 individual dual-polarized channels having 100 GHz channel spacing up to 100 km transmission distance in a single-mode fiber. Each carried a 20 Gbit/s bit rate per channel and achieved 0.64 Tbit/s (16 wavelenghts×2 polarization state×20 Gbit/s), a net data rate with 21% spectral efficiency. The stability analysis of this technique was conducted by undertaking an FEC limit (Min Log BER= -3) calculation to get the minimum allowable OSNR (25.3 dB) in the transmission link.
