OCuLink PCIe PCI-Express SFF-8611 8x 8-Lane to Dual SFF-8639 U.2 4x SSD Data Active Cable 50cm

This industrial-grade active OCuLink breakout cable adheres to SFF-9402, PCIe 4.0 and NVMe industrial standards, integrated with high-performance signal retimer circuitry to resolve signal loss issues that passive cables cannot overcome at 100cm wiring length. It converts one 8-lane SFF-8611 OCuLink host port to two separate SFF-8639 U.2 interfaces, enabling simultaneous connection of two U.2 NVMe solid-state drives.

It delivers up to 16GT/s per lane PCIe 4.0 bandwidth and maintains full backward compatibility with PCIe 3.0 hardware, ideal for all-flash storage servers, AI computing workstations, video editing rigs and JBOD multi-drive arrays. Constructed with high-purity silver-plated twinax conductors and double aluminum foil + braided shielding, the cable drastically reduces electromagnetic interference and signal degradation inside dense rack chassis.

Ultra-slim flexible braided cable structure tidies messy internal wiring and greatly improves cabinet heat dissipation efficiency. All connectors adopt thick gold-plated contacts with auto-lock latches to avoid loose contact under long-term heavy read-write workloads. All raw materials meet RoHS flame-retardant safety standards for data center equipment.

Plug-and-play design requires no extra driver installation, supporting Windows, Linux and mainstream NAS operating systems. Perfect for OCuLink HBA/controller cards connecting dual SFF-8639 U.2 backplanes, high-capacity storage expansion and low-latency NVMe RAID deployment in hyperscale computing nodes.
