InfiniBand/fibre optic cable BlueOptics BL464601N0.5M30-BL 0.5 m MiniSAS-HD

The BlueOptics BL464601N0.5M30-BL is a 0.5 m InfiniBand/fibre optic cable with MiniSAS-HD (SFF-8644) male connectors on both ends. Designed for short-distance, high-speed connections in data centers and high-performance computing environments, this MiniSAS HD Twinax cable supports SAS protocols and provides a compact, low-latency link between external SAS hardware such as drives and storage enclosures. The passive construction relies on host and device controllers for signal conditioning, offering a simple, durable solution for direct-attached storage and rack-level interconnects.

Advantages

This MiniSAS-HD cable offers a high bandwidth path with support for up to 12 Gbit/s data rates and backward compatibility with 6 Gbit/s SAS. The compact SFF-8644 connectors enable high-density rack layouts while requiring minimal space. Passive twinax design results in low power consumption, low latency and a reduced failure rate compared with more complex active alternatives. The cable is manufactured to meet industry standards and is suitable for environments requiring long service life and predictable behavior.

Suitable for

• Connecting external SAS hard drives and storage enclosures
• Direct-attached storage (DAS) links within server racks
• High-performance computing and data center interconnects
• Short-distance high-throughput links between controllers and storage arrays

Key specifications

• Length: 0.5 m
• Connector type: MiniSAS-HD (SFF-8644) male to male
• Supported protocols: 6 Gb/s SAS and 12 Gb/s SAS
• Maximum transmission rate: up to 12 Gbit/s
• Design: passive twinax copper construction
• Typical power consumption: very low (approx. 0.1 W per link)
• Compliance: designed to meet SFF-8644 mechanical and electrical specifications

How to use

Install the BlueOptics BL464601N0.5M30-BL by inserting the SFF-8644 connectors firmly into compatible MiniSAS-HD ports on your host controller and external SAS device. Ensure connectors are aligned with the keyed interface and fully seated to establish reliable electrical contact. Because this is a passive cable, ensure both connected devices support passive MiniSAS-HD twinax cabling and the desired SAS protocol speed. Route the cable to avoid sharp bends and mechanical strain; secure as needed within the rack to prevent connector stress.

Recommendations

Use this 0.5 m MiniSAS-HD cable for short, high-bandwidth links inside racks or between adjacent enclosures. Verify compatibility with your SAS controllers and confirm port support for passive twinax cables. For longer distances or active signal conditioning, consider alternative active or fibre-based solutions. Regularly inspect connectors for contamination and ensure secure seating to maintain optimal performance.
