We designed and constructed a 24×24-port optical circuit switch (OCS) prototype with a programming time of 68.5 µs, a switching time of 2.8 µs, and a receiver electronics initialization time of 8.7 µs [1] . We demonstrate the operation of this prototype switch in a data center testbed under various workloads.
