Active Optical Cable Market - By Speed (10G, 25G, 100G, 400G, 800G), By Application (Data Center, HPC, Consumer Electronics, Medical Imaging, Broadcasting), By Form Factor (QSFP, SFP, CXP, MiniSAS), By Region

The global active optical cable market size was USD 4.22 Billion in 2025 and is expected to register a revenue CAGR of 13.1% during the forecast period. Active optical cables integrate optical transmitter and receiver electronics within the cable assembly itself rather than in the host device, enabling optical fiber interconnects that terminate in standard electrical connectors compatible with host equipment ports designed for copper cable or pluggable transceiver connection. AOCs eliminate the need for separate pluggable transceivers and provide pre-terminated optical fiber runs at lengths from 2 to 100 metres, covering the intra-rack, inter-rack, and row-to-row connectivity distances in data center infrastructure that require optical signalling but do not need the reconfigurability of pluggable transceiver modules. The AOC market spans speeds from 10G SFP+ AOCs in legacy data center deployments to 800G QSFP-DD AOCs in AI GPU cluster interconnect, with the data center segment representing the dominant revenue application. InfiniBand 400G HDR and NDR AOCs connecting NVIDIA GPU clusters represent the highest-volume single-technology AOC application in 2025, driven by GPU cluster build-out at hyperscalers and HPC centres. Lumentum, Amphenol, II-VI, Molex, and FS.com are the primary AOC suppliers.

The AOC market is driven by AI GPU cluster interconnect requirements where NVIDIA NVLink fabric within racks and InfiniBand or Ethernet fabric between racks require optical cables at distances where copper cannot achieve the signal integrity required at 400G and 800G speeds, the data center top-of-rack switch to server connectivity transition from 25G copper to 100G optical at servers with multiple GPU slots, and the broadcast media industry's transition from SDI coaxial cable infrastructure to fiber-based active optical cable for 4K and 8K video distribution. NVIDIA's NVLink 5 architecture in Blackwell GPU clusters requires NVLink AOCs for connections between NVLink switches and GPU trays at 5 to 30 metre reach, with each NVL72 rack requiring 36 NVLink AOC connections. For instance, in April 2026, Amphenol Corporation, USA, reported its optical cable segment revenue at USD 680 million for fiscal year 2025, a 31 percent year-over-year increase driven by GPU cluster InfiniBand and NVLink AOC supply to three US hyperscalers, with 800G AOC representing 42 percent of segment revenue compared to 18 percent in 2023. These are some of the key factors driving revenue growth of the market.

However, the AOC market is under increasing competitive pressure from silicon photonics-based co-packaged optics and linear-drive pluggable transceiver technologies that eliminate the cable assembly entirely at the highest-bandwidth applications, potentially reducing the AOC addressable market in data center switch-to-switch connections over a 5 to 7-year horizon. AOC pricing at 400G and 800G faces compression from Chinese suppliers entering the market with silicon photonics-based AOC designs at 20 to 30 percent lower pricing than US and Japanese suppliers, following the same competitive pattern seen in pluggable optical transceivers. The InfiniBand AOC market is dependent on NVIDIA's InfiniBand ecosystem adoption, and the growing competitiveness of RoCE Ethernet alternatives could shift GPU cluster networking to Ethernet AOCs where the supplier pool is larger and pricing more competitive. These factors substantially limit active optical cable market growth over the forecast period.
