| Popis: | We experimentally characterized and optimized link performance of a multi-node flexible spectrum network. The cheap and low power consuming and wavelength tunable vertical cavity surface-emitting lasers (VCSELs) have been used to create colourless and wavelength selective flexible transmitters to enable up to 10 Gb/s per channel/wavelength signals. With a −3.8 dBm VCSEL optical power and chromatic dispersion mitigation, a 25 km multi-node network has been experimentally demonstrated with a transmission penalty range of 0.2–3.2 dB. Moreover, an impairment-aware mathematical model has been created to predict signal continuity for crosstalk and dispersion penalties for a hop-to-hop signal transmission and a bit error-rate (BER) evaluation at the 10-9 threshold level. This study is vital for creating routing and network algorithms for the next-generation optical fibre networks. |
