SFF-8470 CX4 to SFF-8470 CX4 Cable, Ejectors to Ejectors

The SFF-8470 CX4 to SFF-8470 CX4 Cable with Ejectors to Ejectors is a high-performance external SAS copper cable designed for enterprise storage systems, data centers, and high-speed networking environments. This cable provides a reliable external connection between devices equipped with SFF-8470 CX4 interfaces, utilizing ejector-style latches for secure mechanical coupling. Engineered to support high-speed data transfer protocols including SAS, InfiniBand, and 10-Gigabit Ethernet, this solution ensures efficient performance in demanding applications such as storage area networks (SANs), high-performance computing (HPC), and server-to-switch connections. The robust construction with zinc alloy connectors and multi-layer shielding makes it ideal for environments where durability and signal integrity are critical.

Features

• Secure Ejector Latch Design: Features ejector-style latches on both connectors to ensure a secure, vibration-resistant connection, preventing accidental disengagement in demanding environments while allowing for easy insertion and removal.
• High-Speed Data Support: Supports data transfer rates up to 10 Gbps (10GbE) and 12 Gbps (SAS 2.1), ensuring compatibility with high-bandwidth applications like 10-Gigabit Ethernet, SAS expansions, and InfiniBand SDR/DDR.
• Enhanced Signal Integrity: Utilizes high-quality copper cables (e.g., 24AWG or 28AWG) with precision impedance matching (100 Ohm) and multi-layer shielding (foil and braid) to minimize signal degradation, crosstalk, and electromagnetic interference (EMI), ensuring stable data transmission.
• Durable External Construction: Designed for external use with zinc alloy connectors and metal shells providing robust protection against physical damage and environmental factors. The ejector latch design enhances reliability in rigorous data center operations.
• Backward Compatibility: While optimized for SAS 2.1 and 10GbE, the cable maintains compatibility with earlier SAS standards (e.g., SAS 1.0/2.0) and InfiniBand applications, offering flexibility in mixed storage environments.
• Thermal Management: Operates within a wide temperature range (0°C to +70°C standard; -40°C to +85°C industrial options available), ensuring reliability in varying environmental conditions.
