JMTM.2 NVMe M Key to Oculink 4i / SFF8611 Extension Cable PCIe4.0 X4 Gen3 4 Compatible with T10 / SAS-4 SFF-8612 (10cm)

So far, this device seems to work. Plugged into an NVME drive bay, the OS can recognize an old SATA RAID card. The goal is to interface this occulink with a 10 GbE RJ45 adapter, and also a Minisforum DEG1. More to follow.

Worked good for me.

Excellent! Reliably transmits PCIE 4.0 x 4, works great with external GPUs, and a flexible connector? This is THE best m.2 to oculink adapter I've tested out of five different ones I've tried to use. IT WORKS!

I purchased 3 units of different lengths and they all didn't work. Upon disassembling one I found a design flaw that can prevent them from working with some oculink devices. This is where it gets technical. Oculink has 42 pins, but this only has 24 wires. After the 18 main PCIe wires and the 4 for power and ground, that leaves 2 wires for the 3 auxiliary PCIe signals. The issue arises in that the clock request signal is routed to the oculink port, even though the standard doesn't make space for it. So if your device doesn't know to break the standard as well the clock will never get requested and the communication will never happen. Luckily this is something that can be fixed in the field, but it shouldn't have to be.

Bought this little gem for my Minisforum UM 760 Slim that did not come with oculink. Works like a champ! Paired with the Minisforum DEG 1 and a 7900xtx it works great! Highly recommended!

It works well with um790 pro!

I wanted to convert DEG1 Oculink to USB4 for Minisforum V3 connectivity. This works, the DEG1 and a 40 Gbps NVME M.2 dock make GPU connection for V3 and DEG 1 E GPU. Very pleased!

Used this with a pcie eGPU Oculink dock, worked fine to boot up into Linux from a live usb, as expected.Will return to update if I have issues, otherwise assume its good.
