    8 === Planned Vision ===
    9 The figure below describes the planned vision for COSMOS' optical network. As shown, a central Calient S320 320×320 space switch (SS) in the Data Center at Columbia provides a remotely configurable fiber plant network core. Each fiber supports 96 fully transparent channels, which are flexgrid configurable to provision 10/100 Gbps wavelengths. 20 ROADM units are connected to the central SS via 20×4 add/drop fiber pairs. In addition, 20×16 add/drop pairs connect the ROADM units to top of rack (ToR) switches and servers in the data center at Columbia. The 20 fiber pairs per ROADM can be reconfigured to support various requirements from connected servers through top-layer user applications orchestrated by an SDN controller. The central SS is directly connected via dark fiber (provided by !ZenFi and NYC) to the colocation site at 32 AoA that also houses the NYU data center [1, §4.3].
