roadm mux

The roadm mux tag covers content related to Microsoft's dual-domain optical campus network, which pairs a production ROADM transport with a physically independent MUX-based backup for business continuity and disaster recovery. This architecture applies Zero Trust principles to physical optical infrastructure, ensuring high-throughput labs, datacenters, and cloud-adjacent services remain operational during systemic failures. Discussions focus on optical engineering, operational segregation, and resilience design within enterprise IT environments.
