Engineered to meet industry-leading standards, this cable supports multi-protocol compatibility including PCIe 4.0, SAS 4.0, and backward adaptation to PCIe 3.0/SAS 3.0 devices, eliminating costly hardware upgrades. It boasts a maximum data transfer rate of up to 24 Gbps, with the 8I to dual 4I configuration intelligently splitting 8 high-speed lanes into two independent 4-lane channels—ensuring balanced bandwidth distribution without signal degradation. Constructed with 30 AWG high-frequency copper conductors and multi-layer shielding (aluminum polyester tape + tinned copper braid), it effectively suppresses EMI interference and crosstalk, maintaining optimal signal integrity in dense server racks.
The cable features SFF 8611 male connectors on both ends, with the 8I connector for array cards/RAID controllers and two 4I connectors for SSD backplanes, NVMe enclosures, or storage modules. Its built-in locking latch design ensures a secure fit, preventing accidental disconnections caused by vibration or routine maintenance. Measuring 0.5m to 1m in length, the slim and flexible cable facilitates easy routing inside 1U/2U servers without obstructing airflow, a key factor for thermal management in high-density setups. It also meets UL 20744 safety certification and RoHS standards, ensuring reliability and environmental compliance for 24/7 continuous operation.
Widely applicable in data centers, cloud computing platforms, and high-performance workstations, this cable excels in scenarios such as RAID array expansion, multi-node storage interconnection, NVMe drive deployment, and GPU-accelerated computing systems. It is fully compliant with SFF-9402 standards, seamlessly integrating with mainstream HBA/RAID cards and storage enclosures from leading brands. Whether building new high-bandwidth storage architectures or upgrading existing systems, it simplifies wiring complexity while maximizing connectivity efficiency.
For IT professionals and system integrators, this Oculink SFF 8611 cable stands out with its robust performance, broad compatibility, and long-term durability. The gold-plated contacts enhance corrosion resistance, supporting over 250 mating cycles for extended service life. Backed by a 2-3 year warranty, it provides peace of mind for mission-critical applications. As a cost-effective breakout solution, it balances high bandwidth, compact design, and stable transmission—making it the ideal choice for modern server data transmission needs.
