100G > 400G > 800G > 1.6T

The world’s networks are entering rush hour. Data volumes are increasing, driven by AI, cloud computing, streaming, and real-time analytics and legacy 100G networks are nearing capacity. To keep pace, enterprises and data centres are embarking on a journey to 400G, 800G, and soon 1.6T.

The Challenge? The primary challenge in the upgrade journey lies in managing the increases in power consumption, heat density and signal complexity within existing infrastructure constraints.

As businesses scale their operations and data requirements grow exponentially, the backbone of reliable connectivity lies in the quality of optical transceivers powering these networks. At Ampito, we’re committed to delivering enterprise-grade managed services built on best-in-class components which is why we’ve partnered with T1 Nexus for our optical transceiver needs.

Why Optical Transceivers Matter More Than Ever

Optical transceivers are the backbone of modern networking – the bridge between fibre optics and networking equipment. As data volumes surge and the need for faster, more resilient connectivity grows, organisations need optical components that perform flawlessly, are interoperable across vendors and provide long-term reliability without inflating costs.

T1 Nexus designs and manufactures optical transceivers that meet the highest standards for performance and compatibility.  As a trusted manufacturer, their products are fully tested for interoperability with leading switch and router brands, ensuring seamless integration across complex environments.

Mapping the Upgrade Journey:

100G → 400G → 800G → 1.6T

Upgrading network capacity is rarely straightforward. Each speed tier introduces new decisions around form factor, fibre type, reach, power budget, and interoperability.

T1 Nexus simplifies this with products designed for both performance and flexibility:

• QSFP-DD: Compact, power-efficient, and backward-compatible – ideal for incremental 400G deployments.
• OSFP: Larger and thermally advanced – built for the next phase of high-performance networking and 1.6T readiness.

Together, they create a clear roadmap for scalable connectivity, helping organisations balance immediate needs with long-term evolution.

Engineering Smoother Network Upgrades

The right hardware is only half the story. Successful migration also depends on timing, design, and lifecycle support. That’s where Ampito brings value as a Managed Service Provider.

Ampito ensures every upgrade runs on schedule and on budget through:

• Vendor-neutral interoperability – ensuring your optical components integrate with your existing infrastructure.
• Performance-driven design – leveraging T1 Nexus transceivers to boost throughput, reduce latency, and support future network expansion.
• Sustainability and cost-efficiency – by extending hardware lifespan and reducing unnecessary equipment refresh cycles.
• End-to-end network design and consultation – from design to deployment, Ampito manages your optical environment with proactive monitoring and service continuity

The Future of Fibre: 1.6T and Beyond

With 1.6T optics already on the horizon, networks must prepare for denser, faster, and more energy-intensive environments. T1 Nexus’s designs, paired with Ampito’s strategic planning and managed infrastructure, ensure customers can transition smoothly to the next wave of network capacity. Whether connecting data centres, supporting AI workloads, or scaling hybrid cloud environments, Ampito and T1 Nexus deliver the optical foundation for intelligent, high-capacity networks.

Through the Ampito and T1 Nexus partnership, we deliver an end-to-end fibre strategy combining T1 Nexus’s fibre optics with Ampito’s network design, deployment and lifecycle management expertise.
