10G optical module shipment volume

In 2025, 10G optical modules accounted for approximately 40% of global optical transceiver shipments, with total shipments projected at around 12.8 million units.Shipment OverviewGlobal optical transceiver shipments surged from 20.4 million units in 2024 to 31.9 million units in 2025, representing a 56.5% year-over-year increase. Within this total, the 10G series comprised 40% of the volume, primarily driven by legacy network upgrades, 5G PON deployments, and enterprise data center expansions (resulting in roughly 12.8 million 10G units) . The remaining volumes were dominated by higher-speed modules, including 400G and 800G variants, which together accounted for 30% of shipments .Market DriversThe growth in 10G module shipments is fueled by several factors:5G Network Rollout: Over 2.5 million new 5G base stations were activated globally in 2025, increasing demand for 10G and 25G optical links for front-haul and mid-haul connections .Data Center Expansion: Hyperscale cloud providers such as AWS, Microsoft Azure, and Alibaba Cloud are deploying AI training clusters, which require high-density optical interconnects. While 400G and 800G modules dominate new GPU cluster deployments, 10G modules remain critical for legacy and edge infrastructure .Cost and Availability: 10G modules benefit from lower unit costs and widespread compatibility, making them attractive for incremental network upgrades and enterprise deployments .Regional DistributionChina: Over 30% of 10G shipments, supported by state-backed 5G and data center initiatives .North America: Approximately 25%, driven by AI and cloud infrastructure investments .Europe: Around 20%, with industrial 5G and enterprise network upgrades contributing .Emerging Markets: India, Brazil, and other regions accounted for 15%, primarily through fiber-to-the-home and metro network expansions .OutlookWhile the market is increasingly shifting toward higher-speed modules (100G, 400G, 800G), 10G optical modules continue to represent a significant portion of shipments, particularly for legacy network upgrades, 5G PON, and enterprise applications. The combination of cost efficiency, broad compatibility, and ongoing 5G deployments ensures that 10G modules will remain relevant in the near term, even as the industry transitions to higher data rates .
