Lenovo lists this part as the SFP+ SR Transceiver, feature code 5053 (option 46C3447), and describes it in its BladeCenter documentation as a 10GBase-SR 10GbE 850 nm fiber SFP+ transceiver. It is a short-reach optic for multimode fiber with an LC duplex connector; the BladeCenter guide gives 10GBASE-SR reach as up to 300 m.
It is still listed in current ThinkSystem product guides. Lenovo Press includes it among the supported 10 Gb transceivers for the ThinkSystem Broadcom 57414 10/25GbE SFP28 adapters and the Broadcom 57504 10/25GbE SFP28 4-port adapters, so it can run their SFP28 ports at 10 Gb.
In the 10Gb Ethernet Pass-Thru Module for BladeCenter, Lenovo requires one transceiver for each of the module's 14 external 10 Gb ports, up to 28 per chassis with two modules; that module is withdrawn from marketing.
Other 10 Gb SR optics appear on the same Lenovo transceiver lists, including the SFP+ Transceiver 10GbE SR 300m MMF 69Y0389 and the QLogic 10Gb SFP+ SR optic 49Y4218; the SFP+ LR Transceiver 90Y9412 is the long-reach alternative for single-mode fiber. When pairing with the Broadcom 57414 adapter, remember Lenovo does not support mixing 10 Gb and 25 Gb transceivers on that card. Confirm that the link partner is a 10GBASE-SR port and the cabling is multimode fiber with LC connectors.
