This guide provides a systematic selection process to help you choose the right QSFP28 module every time. You will learn how to verify form factor compatibility, match fiber and distance requirements, validate switch compatibility, consider thermal constraints, and avoid. Both QSFP28 and 100 Gigabit CFP form factors are prominent options when deploying 100G+ links. But which is right for what scenario? This article delves deep: technical definitions, comparative metrics, and advice for choosing the best module type depending on your network requirements. In data centers, high-performance computing clusters, and high-speed network cabling, AOC cables (Active Optical Cables) have become the mainstream solution for short-distance interconnections due to their low power consumption, high bandwidth, and resistance to electromagnetic interference.

It is widely used in data centers, enterprise core networks, and telecom infrastructure due to its high port density, standardized interface. A 100G optical module is a high-speed communication device designed for data centers and telecommunication networks, capable of supporting transmission rates of 100 Gbps. These modules convert electric signals into optical signals, enabling efficient data transmission over optical fibers. 25G is the new 10G; 100G (QSFP28) is the workhorse; design for migration plans to 400G/800G.
