Lenovo 100GBase-SR4 QSFP28 Transceiver

This is a second Lenovo 100GBase-SR4 QSFP28 listing, identified by feature code AV1D. The 7G17A03539 uses four parallel lanes and fits a QSFP28 cage on a switch or adapter.

Confirm the media type, reach and host compatibility before ordering. As with other 100G optics, the thing to verify is your fiber plant: SR4 links use parallel fiber with matching connectors on the patch panels, and mismatched cabling is the most common reason a new 100G link will not come up.

Why two listings for the same standard? Lenovo issues new part numbers and feature codes as products are refreshed or sourced from different makers. If your configuration lists AV1D, this is the part; if it lists BVA4 or BFH1, one of the other listings applies.

The 7G17A03539 is available new, refurbished and used. New and refurbished units carry a choice of 1 year or 3 years of warranty. Used units carry 90 days. Send quantity and equipment models for pricing.
