Overview

InfiniBand NDR is a high-performance cluster fabric, and the 4TC7A81826 is its single-port multimode transceiver in the OSFP form factor. The 400 in OSFP400 refers to the port rate class of the module.

The one listed compatible system is the SD665-N V3 Neptune DWC, a water-cooled node used in dense compute clusters. In that kind of build, optics are specified with the rest of the fabric, and mixing the wrong module type can leave a port dark. Send us your adapter and switch models, and we will check the pairing.

The word Solo in the title marks this as a single transceiver, as distinct from the twin version listed for the same node.

Lenovo's feature code is BQJT. The part is offered refurbished and used. No new offer is listed. Refurbished units carry a choice of 1 year or 3 years of warranty, and used units carry 90 days.
