Our company recently migrated its primary backup cluster to a dedicated SAN fabric. We chose these 25G SFP28 multi-mode optical transceivers to bridge the 80-meter distance between our backup arrays and the core switch. Using OM4 fiber, the links established instantly at 25Gbps. We pulled the DDM data via CLI, and the optical output levels are perfectly optimized to prevent saturation while ensuring high signal-to-noise ratios. The modules fit snugly into our SFP28 ports with no loose play. The low power consumption is definitely a bonus for high-density networks where thermal management can be tricky.

Bought a batch of these LS-MM8525-S1C 25GBASE-SR modules for a Core-to-Aggregation link upgrade in our Chicago office. They hit full 25G speeds over 85m of OM4 fiber without any fuss. The built-in DOM allows real-time diagnostics on our Enterprise switches. Real lifesaver for the price!

Modules perform exactly as advertised, hitting full 25G line rates over our 60m OM3 fiber runs. My only tiny complaint is that the pull-tab latches are a bit stiff on first insertion compared to our old 10G optics. They seat securely though, and DOM telemetry is perfect. Good budget choice.
