Passive ROADM Flexibility in Optical Access With Spectral and Spatial Reconfigurability


An energy-aware answer for physical-layer reconfigurability in metro-access networks is presented. The dynamicity of optical switching is introduced in nodes that are perceived as absolutely-passive by the network. Energy scavenging at low optical feed level of $- 10;textdBm$ supports field-deployment without local electrical power provide. 2 types of network nodes are demonstrated experimentally. Initial, a resilience node is evaluated for quick protection switching in ten.7 ms at the feeder phase. Optical switching is any exploited for the purpose of dynamic allocation of spectral slices and routing in a new class of reconfigurable optical add-drop multiplexer. The spectral bandwidth of drop segments will be extended on demand whereas intranetwork communication among completely different segments of the access network is additionally enabled. Finally, we have a tendency to discuss the potential for realizing self-powering by suggests that of tapping optical signals traversing the access network rather than utilizing a frenzied pump supply.
