    Selection Guide for QSFP Long-Distance Optical Transceivers for Data Center Interconnection

    This guide explains how to choose QSFP-DD transceivers step by step, helping you avoid costly mistakes and ensure compatibility across your network. Before selecting reach or connector type, evaluate the form factor based on your current switches and long-term upgrade path. That's where QSFP LC comes in: it combines the high-density QSFP footprint with familiar duplex LC fiber connectivity, making it a practical path to high-speed links without overcomplicating fiber management. 25G is the new 10G; 100G (QSFP28) is the workhorse; design for migration plans to 400G/800G. This article provides a comprehensive comparison of mainstream optical transceivers, including SFP, SFP+, QSFP+, QSFP28, and QSFP-DD. Last March, a mid-sized cloud provider ordered 400 QSFP-DD SR8 modules for a new data center. While their switching platform and target speeds were correct, they overlooked a key detail: connector type.
