CAB861139 50cm Oculink SFF-8611 4i 38Pin to SFF-8639 U.2/U.3 NVMe SSD Cable, PCIe 4.0 Mini SAS Adapter Cable with 15-Pin SATA Power for Server Mainboard NVMe Storage Drives

Model CAB861139 is a 50cm high-speed Oculink Mini SAS conversion cable designed to connect SFF-8611 4i 38Pin Oculink RAID controllers or motherboard Oculink headers to SFF-8639 U.2 / U.3 NVMe SSDs. Fully compliant with PCIe 4.0 NVMe protocol, it delivers full x4 high bandwidth without performance bottlenecks for enterprise storage, workstations and rack servers.

Equipped with an independent 15Pin SATA power branch, it directly provides stable 3.3V/5V/12V power supply to U.2/U.3 SSDs without extra separate power wiring. All contact terminals adopt precision gold-plated plating to ensure tight, low-loss plug-in contact during long-term continuous high-load read-write tasks.

Constructed with high-frequency tinned copper conductors and double-layer aluminum foil shielding, the cable effectively blocks electromagnetic interference from GPUs, power supplies and rack hardware to avoid data lag or transmission errors. The slim woven braided outer jacket features great bending flexibility, saving limited internal chassis space and simplifying tidy cable layout.

Plug-and-play without driver installation, widely compatible with mainstream Oculink RAID adapters, server motherboards and all standard U.2/U.3 NVMe SSDs. Every cable passes strict PCIe 4.0 signal integrity and aging tests to meet industrial data center reliability standards, ideal for NVMe RAID array building, server storage expansion and hardware maintenance.
