You've got the network adaptor card in the server, but that SFP+ slot's empty and your 10GbE link isn't going anywhere. Or the old transceiver's gone flaky mid-project and you need a replacement before the client walks off-site. This is the Lenovo 10GBASE-LR SFP+ module. Plug it in, patch your fibre through, and you're running 10 Gigabit over single-mode at up to 10km. It's the exact part for Lenovo network adaptor cards 94Y5180, 00D9700, 44T1360, and 00D2028 — no third-party compatibility guessing. Eleven in stock right now. Add to cart and it's on the next dispatch out of our warehouse
