IBM 45D8628 server / storage / networking hardware Server Hardware / Parts

The IBM 45D8628 is a Stomper2 (STMP2) 1Gb Ethernet adapter with an LX (long-wave, single-mode fibre) optical interface, feature code 57E8, used on IBM System z mainframes and paired with the SX short-wave variant 45D8625 documented elsewhere in this catalogue. The LX/long-wave optic extends reach over single-mode fibre for longer network runs, in contrast to the shorter-reach multimode SX variant, giving frame planners a choice matched to their cabling distance. Stomper2 cards of this generation remain in service on System z frames that have not migrated to a newer network adapter standard. Specifiers should confirm the fibre type (single-mode versus multimode) already run to the frame before ordering, since LX and SX optics are not interchangeable on the same link. Tech-Star (UK-based, shipped worldwide) stocks IBM System z components to support ongoing mainframe network projects.
