Lenovo 25Gb Ethernet Optical SFP28 Shortwave Module 1 Pack

This is an optical module, not a network card. The Lenovo 25Gb Ethernet Optical SFP28 Shortwave Module (MPN 4XF7A39597) is sold as a 1 Pack and carries a 25GbE link in the SFP28 form. The word Shortwave in the title marks it as a short-reach optic, intended for runs inside a room or between nearby racks over fiber.

It has a 25GbE link speed, an SFP28 connector and feature code B732. It gives no reach figure and no list of compatible switches or adapters, so match it to the port on each end of the link before ordering. Both ends need to be SFP28 cages that accept this module, and some vendors lock ports to their own optics.

The module is available new and refurbished, each with a choice of 1 year or 3 years of warranty, and used with 90 days. Tell us the device models on both ends and the number of modules and we will reply with pricing and availability.
