Eoptolink Technology has launched the industry’s first 12.8 Tbps XPO pluggable optical transceiver. It’s built for AI data center architectures that need to scale up, scale out, and stretch across metro-reach fabrics.
This device delivers ultra-high density and features advanced liquid cooling. It’s a new benchmark for power-aware, high-performance optics in modern data centers.
You’ll also find some discussion of industry collaboration, deployment considerations, and what operators might see at big events like OFC 2026.
Technical prowess and performance
The XPO transceiver packs 64 lanes running at 200 Gbps each. That adds up to a hefty 12.8 Tbps per module and a striking 204.8 Tbps front-panel density within a 4-RU rack.
This density is four times better than current 1.6T OSFP solutions. Operators can squeeze more capacity from existing fiber plants and cut down on rack space.
It’s not just about raw speed. The module also focuses on serviceability with front-panel pluggability, which is a lifesaver for anyone trying to upgrade in a packed data center without causing too much downtime.
Thermal design and cooling innovations
The XPO stands out for its liquid cooling system. It uses a cold plate that can handle up to 400 W of cooling per module.
This cooling method keeps things running smoothly even when power demands spike. The optics can hit higher densities without overheating or making maintenance a nightmare.
Pairing high-power electronics with liquid cooling opens the door to denser port layouts and better energy efficiency. Maintenance gets easier, too, which matters a lot in data centers running at full tilt.
Liquid cooling makes it possible to use higher-power optics while keeping thermal efficiency in check. That means more ports per rack and a better total cost of ownership for AI and cloud deployments.
Eoptolink points out that the design keeps the front panel accessible for service and upgrades. That’s a big deal for large-scale networks where routine maintenance can’t grind everything to a halt.
Industry collaboration and standardization
To speed up adoption and ensure things work together, Eoptolink joined the XPO Multi-Source Agreement (MSA) as a founding member. This group wants to define a new class of high-density, liquid-cooled pluggable optics with shared specs and interfaces across vendors and data centers.
By joining the MSA, Eoptolink shows its commitment to open standards and reliable interoperability. That’s really important as AI workloads keep demanding more bandwidth and consistent performance.
At industry showcases, Eoptolink will display the 12.8T XPO along with other high-speed transceivers like the 400G/lambda-1.6T DR4 and 200G/lambda-1.6T FRO/LRO/LPO series at OFC 2026 in Los Angeles.
The company believes that combining front-panel pluggability with liquid cooling gives operators the deployment flexibility they need as they scale up AI and cloud data centers.
Market implications for AI and cloud data centers
AI accelerators and data-hungry workloads keep reshaping data-center design. The need to scale bandwidth in a tight footprint is more valuable than ever.
The 12.8 Tbps XPO platform tackles several big needs:
- High-density optics that shrink rack space and lower power use per bit.
- Advanced liquid cooling to handle higher power without overheating.
- Flexible interfaces—linear, half-retimed, and fully-retimed—to fit a range of network setups.
- Industry standardization through the XPO MSA for better interoperability and quicker rollouts.
- Clear advantages for operators looking to future-proof their AI data centers and metro networks.
Eoptolink’s 12.8 Tbps XPO pluggable transceiver takes a bold leap toward ultra-dense, liquid-cooled optical interconnects for AI-ready networks. Extreme density, solid cooling, and front-panel serviceability match what modern data centers need for scalable and maintainable infrastructure.
Conclusion: paving the way for AI-ready networking
Eoptolink’s XPO platform points toward high-density, liquid-cooled pluggable optics that tackle rising bandwidth needs while keeping things manageable.
Their MSA partnerships and plans for OFC 2026 hint at a bigger shift. The industry seems to be leaning into standardized, scalable, and thermally smart solutions for AI-focused data centers and metro networks.
