Fast control SOA-Based Optical Switched Metro-Access Network with Edge Computing Nodes for Time-Sensitive Applications

We propose and demonstrate a metro access network based on fast SOA-based optical add/drop multiplexer (OADM) nodes and the fast control plane implemented with an FPGA-based supervisory channel. Experimental results show dynamic switching with microsecond-time control, time-slotted operation and deterministic latency with nanosecond jitter suitable for critical time sensitive applications. Node cascadability is also investigated. Results show that transmission and switching through five OADM nodes are successfully demonstrated.
