High-speed OCuLink cable for PCIe connections, designed to bring PCIe 4.0 bandwidth to external GPUs and SSD backplanes. chenyang OCuLink Cable helps gamers and workstation builders achieve more responsive systems and tidier external enclosures. Is the combination of active signalling and wide GPU compatibility right for your setup?
⚡ At a Glance
- • Data Transfer: Up to 64Gbps, transmits PCI Express 4.0 signals via OCuLink SFF-8611
- • Best for: Gamers and professionals linking external GPUs or NVMe backplanes to controllers
- • Not ideal for: Users who require consumer USB or Thunderbolt connectivity rather than OCuLink
Active OCuLink cable routes PCIe 4.0 signals over a 50cm active link for backplane-to-controller connections. Designed for external GPUs and SSDs, offering high-bandwidth external PCIe connectivity.
Maximum throughput for external storage and GPUs – thanks to PCIe 4.0 OCuLink signalling
Active cable transmits PCI Express 4.0 signals over SFF-8611 connectors and handles the protocol overhead while preserving lane integrity. The specification supports up to 64Gbps data transfer rates.
Higher transfer throughput shortens load and transfer times for NVMe arrays and improves external GPU data delivery during gaming and workstation tasks.
Stable connections for demanding builds – with active cable design and 4i configuration
On-board active circuitry maintains signal quality across the 50cm run, while the 4i configuration routes multiple PCIe lanes through SFF-8611 terminations. The active approach counters attenuation that passive cables struggle with.
Consistent, quiet operation suits long gaming sessions and sustained workstation workloads, as user reports note reliable behaviour and wide GPU compatibility.
Quicker, simpler installs for enclosures and backplanes – with SFF-8611 connectors
SFF-8611 form-factor connectors align with many backplanes and controllers so direct linking is possible without complex rewiring. User feedback also mentions included OCuLink and PCIe adapters that simplify setup.
Fast, tidy installations reduce build time for external GPU or NVMe bays and lower the chance of connection errors during assembly.
