2. Hyperscale Data Centres

With the exponential growth of cloud computing, AI, and big data analytics, hyperscale data centres are scaling rapidly. Next-gen transceivers facilitate:

• High-capacity interconnects between data centres.
• Efficient east-west traffic management within the data centre.

3. Edge Computing

Edge computing requires robust, high-speed optical connections to process data closer to the source. Transceivers with advanced functionalities like coherent optics are being deployed to ensure ultra-reliable, low-latency connections at the edge.

4. AI and Machine Learning Applications

Artificial intelligence and machine learning workloads require massive parallel processing and real-time data exchange. High-speed optical transceivers meet these demands by:

• Enabling faster communication between GPUs.
• Supporting high-bandwidth, low-latency requirements of AI clusters.

5. Migration to 400G and Beyond

The industry-wide shift towards 400G and beyond is being fuelled by growing data consumption. Next-gen transceivers like QSFP-DD and OSFP are designed to:

• Handle higher data rates with ease.
• Minimise power consumption per bit.

6. Sustainability Goals

As sustainability becomes a cornerstone of corporate strategies, next-gen transceivers are addressing environmental concerns by offering energy-efficient designs. Many manufacturers are also prioritising recyclable materials and reducing e-waste.

7. Advances in IoT and Smart Cities

The proliferation of IoT devices and the growth of smart cities demand robust and scalable network infrastructures. Next-gen transceivers provide the bandwidth and reliability required to handle the vast amounts of data generated by these technologies.
