In well-cooled data centers, common modules such as SFP+ or QSFP28 often run reliably for 5–7 years. Their lifespan depends on a mix of design, environment, and how they're used in real-world conditions. As a practical baseline, short-reach modules in clean, cooled data centers usually give you five to seven years of solid service; the most conservative shops plan for three to five years for edge racks, wiring closets, and any place where temperature and handling are outside ideal ranges. In many environments, optics get replaced every 2–3 years—not because they fail, but because that's what the OEM lifecycle tells you to do. An Aging Test (or Life Test) is a longer-duration evaluation designed to simulate the effects of operational wear and tear over the transceiver's intended lifespan. How do I know when to start proactively replacing old SFPs? Is that even something I need to worry about? 03-22-2021.
