BlueOptics BL464801GN1M30-BL InfiniBand/fibre optic cable 1 m 4x MiniSAS-HD 4x MiniSAS

The BlueOptics BL464801GN1M30-BL is a 1 m InfiniBand / fibre optic hybrid cable with 4x MiniSAS-HD (SFF-8644) on one end and 4x MiniSAS (SFF-8088) on the other. Designed for data center and enterprise environments, this male-to-male cable provides a compact external MiniSAS x4 connection for linking storage controllers, expanders and SAS devices across short rack distances. The cable supports high-speed SAS connectivity and is intended to offer reliable signal transmission for rack-level interconnects.

Advantages

The cable combines MiniSAS-HD and MiniSAS connectors in a single 1 m assembly to enable direct external SAS x4 connections between compatible devices. Its slim connector form factor reduces required rack space and simplifies routing in dense installations. As a passive MiniSAS twinax-style solution, it does not require additional power or active components in the cable itself and is suitable for short-distance, high-bandwidth links. Male-to-male connectors ensure straightforward installation and broad compatibility with devices using SFF-8644 and SFF-8088 interfaces.

Suitable for

• Connecting SAS controllers to external storage enclosures or JBODs within racks
• Inter-rack links where short, high-speed SAS x4 connections are required
• Server-to-storage connections in data centers and enterprise storage systems
• Replacing or extending existing MiniSAS SFF-8088 to SFF-8644 external connections

Key specifications

• Length: 1 meter
• Connector types: 4× MiniSAS-HD (SFF-8644) to 4× MiniSAS (SFF-8088)
• Configuration: 4x external MiniSAS x4 hybrid connection (twinax style)
• Intended application: external SAS x4 interconnects for storage and servers
• Transmission class: designed for short-distance, high-bandwidth SAS links (supports SAS protocols)

How to use

Install the BlueOptics BL464801GN1M30-BL by aligning the SFF-8644 and SFF-8088 male connectors with the corresponding female ports on your controller, host adapter or storage enclosure and push until the connectors seat securely. Route the cable to avoid sharp bends and sources of electromagnetic interference; maintain the 1 m length for optimal signal integrity. Verify the host and target devices support the external MiniSAS SFF-8644 / SFF-8088 interfaces and SAS protocol versions in use before powering the system.

Recommendations

Use this cable for short rack or adjacent-rack connections where a compact, passive MiniSAS x4 twinax solution is appropriate. Avoid extreme bends and mechanical strain on the connector ends; inspect connectors for contamination before insertion. For longer distances or active signal conditioning, choose an appropriate active cable or fibre solution certified for the required link length and protocol.
