Pluggable Optics
High-speed optical transceivers powering Ethernet, AI fabrics, storage networks, and data center interconnects.
OverviewPluggable optics are standardized, field-replaceable optical transceivers that enable high-bandwidth communication between switches, routers, servers, storage systems, and AI accelerators. Their modular design simplifies deployment, upgrades, and maintenance while supporting rapid advances in network speed.
ApplicationsWidely deployed across hyperscale data centers, enterprise networks, telecom infrastructure, cloud fabrics, AI clusters, and metro and long-haul optical transport. Modern deployments increasingly utilize 400G, 800G, coherent ZR/ZR+, and emerging 1.6T transceivers.
