Photonics Market Monitor - Optical Transceivers for Datacom
Datacom optics enters a new scaling cycle as AI infrastructure drives the transition from 800G to 1.6T.
YINTM26560The photonics market is in the heart of the AI-driven scale phase. Through Q1-26, 800G optical modules have hit peak ramp and the first 1.6T deployments are converting from samples to revenue. This Q2-26 monitor captures how AI infrastructure, hyperscaler procurement, and 200G/lane optics are reshaping where volume, value, and vendor power concentrate through 2028.

The objective of this monitor is as follows:
- Provide a quarterly dashboard of the datacom optical transceiver market, covering revenue, shipments, ASPs, and the near-term outlook for pluggable modules in AI and cloud datacenter networks from Q1-2024 though the next 8 quarters until Q1-2028.
- Analyze the main market drivers, demand shifts, and deployment dynamics shaping datacom optics, with focus on Ethernet, InfiniBand, AOCs, hyperscaler build-outs, and AI-driven bandwidth scaling.
- Present detailed segmentation of datacom optical transceivers by product category, including pluggables, AOCs, and integrated optics, to show where volume, value, and technology intensity are building up.
- Track the evolution of high-speed pluggable modules by PMD/reach, highlighting how SR, DR, FR, LR, and related architectures influence module mix, datacenter topology, and revenue creation.
- Assess the market transition by speed tier and speed per lane, from 400G and 800G toward 1.6T and beyond, linking module demand to the broader SerDes, DSP, and switch roadmap.
- Assess the volume demand of major hyperscalers and link it to the top module vendor shipments.
- Evaluate the competitive landscape through optical technology splits and player dynamics, showing how VCSEL, EML, DML, and silicon photonics, along with supplier positioning and supply-chain structure, shape future market leadership.
AI infrastructure is setting the pace, scale, and direction of datacom optics
The center of gravity in optical interconnects has clearly shifted toward AI cluster build-outs, where bandwidth scaling, radix choices, and network tiering directly translate into higher optical content per server and per cluster. The monitor sizes the broader Ethernet & InfiniBand module market at ~$17B in 2025, expanding to ~$36B in 2026 (+110% YoY), ~$54B in 2027, and ~$62B in 2028, confirming that optics is no longer an enablement layer at the edge of compute; it is now one of the main constraints on scaling power, density, and data movement inside the datacenter. This is why the monitor’s datacom focus naturally centers on Ethernet, InfiniBand, AOCs, and the next wave of integrated optical approaches.
1.6T optical transceiver modules are moving towards volume production
While 800G remains the volume and revenue driver in today’s datacom optical module market, the industry’s strategic focus has clearly shifted to the next transition point. 1.6T is converting from samples to production at Innolight, which is projected to hold ~50–60% of 1.6T share in 2026, Eoptolink, with Gen-2 OSFP-XD/RHS platforms using 3nm DSP and ~20% lower power, and Coherent. The real discussion is no longer just about scaling port speed, but about how to enable 1.6T through 200G-per-lane optics, tighter power budgets, more demanding thermal constraints, and a broader move toward new module and system architectures. In that sense, 800G is the market’s commercial backbone today, but 1.6T is already shaping the design priorities, supply-chain decisions, and technology roadmaps that will define the next phase of competition.
What makes this transition especially important is that it is forcing a deeper reset in how optical modules are designed, powered, cooled, and manufactured. The 200G-per-lane EML chip shortage — controlled by Coherent & Lumentum — is now the structural gating factor for 1.6T volume in 2026, pushing the market toward higher-speed lanes, more complex photonic content, and tighter system-level optimization. That is why 1.6T should be seen more as the next competitive filter for the entire datacom optics ecosystem.
Integrated optics are changing the optical adoption within datacenters
As AI clusters grow, the industry is becoming more deliberate about where to use pluggables, where AOCs remain the better fit, and where integrated optics may eventually make more sense, with CPO still in an emerging trend. This selectivity matters because future growth will come not only from more ports, but from the changing role of optics across different layers of the datacenter network.
The monitoring of the split of optical transceiver modules is a key driver toward understanding the datacenter ecosystem
The transition from SR-heavy deployments toward a broader mix of DR, FR, LR and DCI-oriented links reflects a structural change in datacenter design. AI cluster topologies that span multiple buildings or large halls increasingly favor single-mode FR-class reach, pulling the market toward higher-value module architectures. In that sense, PMD evolution is not a secondary technical detail; it is one of the clearest indicators of where future revenue and technology complexity are moving.
