Abstract
The paper investigates possibilities for high-bit rate transmission systems over embedded standard single-mode fiber (SMF) operating at a transmission wavelength of 1.55 μm. We theoretically analyze 40 Gb/s unrepeated return-to-zero single-channel transmission over 150 km SMF using different dispersion compensation schemes and compare the results to experimental data. It is shown that post-compensation allows for higher fiber-input powers and therefore for a higher system margin. We also numerically compare dispersion-managed 4x40 Gb/s, 16x10 Gb/s and 16x40 Gb/s wavelength-division multiplexed (WDM) transmission over 1000 km standard singlemode fiber operating at 1.55 μm. It is shown, that for Nx40 Gb/s the system performance is mainly limited by the degradation of each individual channel. No significant additional degradation due to cross-phase modulation or four-wave mixing could be observed.
