MCIO 8x 74P to 2 OCulink SFF-8611 4x Cable, Straight to Straight

The MCIO 8x 74P to 2 OCuLink SFF-8611 4x Cable is a high-performance internal breakout cable designed for next-generation data centers, enterprise storage, and high-performance computing applications. This cable provides a critical interface conversion, splitting a single high-bandwidth MCIO (Mini Cool Edge IO) 8-lane host port into two independent OCuLink (SFF-8611) 4-lane channels. It is engineered to the SFF-TA-1016 standard on the host side to deliver exceptional signal integrity, supporting PCIe protocols to enable flexible, high-speed data transfer for NVMe storage and accelerator cards in demanding computing environments.

Features

• High-Density Interface Breakout: Efficiently bifurcates a single SFF-TA-1016 (MCIO) 8-lane port into two separate SFF-8611 (OCuLink) 4-lane ports, perfect for PCIe 4.0 and PCIe 5.0 applications, maximizing connectivity in space-constrained systems.
• High-Speed PCIe Support: Designed specifically for the PCIe protocol, this cable is ideal for connecting to NVMe SSDs, GPUs, and other high-performance peripherals that utilize the OCuLink interface, delivering low latency and high bandwidth.
• Superior Signal Integrity: Constructed with precision-engineered twin-axial cables and robust multi-layer shielding to minimize insertion loss, crosstalk, and EMI, ensuring pristine signal quality and stable performance at high data rates.
• Optimized for Dense Layouts: The compact form factor of both MCIO and OCuLink connectors, combined with a flexible cable jacket, facilitates neat routing and improves internal airflow within dense server and workstation chassis.
• Secure and Reliable Connection: Features high-quality connectors with positive latching mechanisms (MCIO dual-push-pull and OCuLink screw-lock) to ensure a secure and vibration-resistant connection, vital for data integrity.
