Cabling Guide ② | 800G/400G: Switch-to-Switch Structured MPO Connectivity Introduction

As data centers continuously evolve towards higher bandwidth and larger scale, 800G optical modules have become critical infrastructure supporting AI computing, high-performance computing, and cloud services. Their importance lies not only in the leap in transmission rates but also in significantly improving the efficiency and density of data exchange through technological integration, reducing per-bit power consumption and cost, and providing core interconnection capabilities for next-generation data centers. In this context, rational cabling strategies are crucial for fully leveraging 800G performance.

800G and 400G – Switch-to-Switch Applications

Using Structured Cabling to Connect MPO-8/12 APC to MPO-8/12 APC

This scenario utilizes MPO fiber trunk cables as the backbone for structured cabling. This solution is primarily used for interconnecting switches, such as achieving leaf-to-spine and spine-to-core layer connectivity. This cabling method is recommended when two active devices are physically located in different areas of the data center.
