Overview
The Lenovo 7G17A03537 is an optical transceiver designed for 25 Gigabit Ethernet connections using the 25Gbase-SR standard over multimode fiber. It operates at an 850 nm wavelength and supports link distances up to 70 meters on OM3 fiber and 100 meters on OM4 fiber. This module fits into any SFP28-compliant slot, making it a practical choice for data centers and network aggregation layers that require high-throughput short-range connectivity.
Its hot-pluggable design allows for easy installation and replacement without interrupting network services, which is essential for maintaining uptime during upgrades or maintenance. The transceiver uses an LC duplex connector, ensuring compatibility with existing multimode fiber cabling infrastructure.

Product warranty
Product warranty
We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.
If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.
Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
