XPM statistics in 100% pre-compensated WDM transmission depends on bit rates, transmission fibres and modulation formats. XPM in DPSK systems shows much less stochastic than that in OOK systems.
2,000 km SMF-28 transmission of a 10 Gb/s signal was achieved without using any dispersion compensation and optical/electronic equalization. The enabling technology was a single-sideband subcarrier-multiplexed optical transmitter using microwave duo-binary modulation in combination with narrowband tunable optical receivers.
In this work we investigate the effects of multiple access interference (MAI) and polarization mode dispersion (PMD) in optical code division multiplexing (OCDM) lightpaths. These paths are determined by the data encoding with non-coherent optical orthogonal codes (OOC), using a sequence inversion keying (SIK) optical correlator system. Our results show the impact of MAI effects and PMD constraint...
We designed and built a novel all-optical re-timing, re-amplifying, and re-shaping (3R) regeneration system based on terahertz optical asymmetric demultiplexers (TOADs) developed in our laboratory. The system is capable of parallel processing multiple wavelengths, a feature which will significantly improve the scalability of current wavelength division multiplexing (WDM) networks. Performance against...
We compare performance of NRZ and RZ modulation in 40 Gb/s multi-span SMF transmission systems by means of simulations and experiments. Use of RZ modulation allows to double transmission distance for a fixed 2 dB penalty.
