-=== 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.

+=== ROADM ===
+There are several Lumentum Whitebox20 degree-one ROADMs (reconfigurable optical add/drop multiplexer) in COSMOS, the majority of which are at the core datacenter. Each of the ROADMs features 20 ports and allows individual wavelengths to be redirected from one fiber strand to another. This permits physically separate network links to share fibers yet still be routable (with no overhead delay) to physically different end-points. The ROADMs are compatible with C-band DWDM. Configuration of the ROADMs is done via netconf.
