Pluggable Optics High-speed optical transceivers powering Ethernet, AI fabrics, storage networks, and data center interconnects. |
| Overview | Pluggable 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. |
| Applications | Widely 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. |
