44X1964 IBM Compatible 10G SFP SR 150m MMF Transceiver

The 44X1964, decoded, is a 10G SFP+ short-reach optic for multimode fiber out to 150m — the IBM-coded version of exactly that. Read straight off the title, the pieces are a 10G rate, an SFP+ cage, MMF, and a 150m span, which is enough to place it on in-rack and intra-row 10G links without guesswork. Nothing beyond those traced values applies; the 150m MMF reach is the outer bound it is rated to.
