Optical

The optical connectivity layer in COSMOS allows an experimenter to reconfigure connectivity between devices at the L1 (physical) layer. This provides the ability to restructure the physical topology of the entire testbed, changing not just latency between nodes but how individual signals are routed, with no overhead, throughout the testbed.

Calient MEMS Space switch

The Calient space switch is a 320x320 any-to-any MEMS optical circuit switch which allows an experimenter to redirect the entire optical link coming in from one fiber strand to another. The switch itself introduces ~2dB of loss to the signal and has a switching time of ~25ms. Configuration of the switch is possible via Openflow and netconf as well as several other methods.
