Implementation of a large-scale multi-stage non-blocking optical circuit switch

摘要: Embodiments provide a methodology for designing large-scale non-blocking OCS using multi-stage folded CLOS switch architecture use in datacenter networks and fiber-rich backbone network POPs. One aspect employs because of its ease implementation, enabling the topology to scale arbitrarily with increasing number stages. The fraction ports allocated internal wiring (overhead) also increases Design decisions are made carefully optimize insertion loss per module, stages total required. Other embodiments include architectures having at least two In one example, power monitoring may be included only on leaf switches.
