Traffic driven variable bandwidth optical transmission

摘要: Link bandwidth is varied based on the subscriber traffic load. Varying link has effect of varying actual noise margin (in an inverse elation), so that will vary inversely with A beneficial result that, because increased during “off-peak” periods, rapidly and burst impairments can be absorbed without causing data loss. In effect, respective probability distributions error bursts load are separated. Data loss only becomes a significant risk when peaks in both coincide. However, event occurring comparatively low. This enables lower allocation design link, which dramatically reduces cost.
