Coherent | Optical Circuit Switch Demonstration at OFC 2024

300×300 port Datacenter Lightwave Cross-Connect (DLX™) is an optical circuit switch (OCS) based on the company’s field-proven and ultrareliable digital liquid-crystal technology to enable new AI network architectures that replace some traditional packet switches with optical circuit switches. Deploying an OCS-based architecture enables operators of artificial intelligence (AI) clusters to dramatically reduce the number of electrical switches required in data center networks, and, more importantly, reduces the costly optical-to-electrical-to-optical (OEO) conversions that such electrical switches require. In an OCS, data signals remain in the optical domain as they transit the switch; eliminating OEO conversion can provide dramatic cost and power consumption savings. Furthermore, unlike traditional switches, the OCS does not need to be upgraded when the AI clusters are equipped with higher-speed connections in subsequent generations. For data centers, this significantly improves the return on capital expenditure.
