HOOCCC Oculink Cable Silver-Plated OcuLink 4i SFF-8611 to SFF-8611 PCIe 4.0 x4 Gen4 Full-Function Extension Cable, 64Gbps High-Speed Data Cable for Egpu

PCIe 4.0 Gen4 x4 High-Speed Performance

Supports up to 64Gbps total bandwidth (16GT/s per lane) for demanding applications such as eGPU docks, U.2 NVMe SSDs, RAID cards, and PCIe expansion chassis. Fully backward compatible with PCIe 3.0 / Gen3 x4 devices.

Silver-Plated Signal Cables with Dual-Layer Shielding

Features silver-plated conductors and a dual-layer structure to reduce skin-effect loss and crosstalk between high-speed signal lines. Aluminum foil Mylar shielding plus EMI/RFI protection ensures clean signal integrity and minimal transmission loss over the full cable length.

Secure SFF-8611 Connectors with 4-Layer PCB Bridge

Equipped with gold-plated / high-conductivity OCuLink 4X 42-pin connectors and a 4-layer PCB board bridge for optimized conductivity, corrosion resistance, and physical durability. The latch / buckle design locks the cable firmly in place and prevents accidental disconnection during operation.

Durable Braided Sleeve & Teflon Insulation

Wrapped in a high-density woven mesh outer layer that improves bending resistance, wear resistance, and tensile strength for long-term internal use. Teflon insulation provides high-temperature resistance and stable high-frequency characteristics even in tight server or workstation enclosures.

Full-Featured OCuLink 4i SFF-8611 to SFF-8611 Extension

All 4 lanes plus sideband signals are fully wired through (SFF-8611 male to male), making it ideal for extending OCuLink / Mini-SAS HD connections to GPU
