## Summary description

The BlueOptics 691971-B21-BL is a 0.5 m InfiniBand/fibre optic cable with SFF-8088 male connectors. It ensures high-performance data transmission in computing environments, ideal for data centers and server rooms.

## Long description

The BlueOptics 691971-B21-BL is a 0.5 m InfiniBand / fibre optic hybrid MiniSAS cable with SFF-8088 male connectors. Designed for rack and adjacent-rack connections in data centers and server rooms, this cable supports MiniSAS twinax copper transmission for SAS devices. It provides a compact, low-power interconnect option for connecting controllers, hard drives and storage hardware where short, high-density links are required.
Advantages
This MiniSAS hybrid cable supports SAS transmission rates up to 6 Gb/s and offers a compact connector design that reduces the space required in dense storage systems. As a passive cable it requires no active electronics, which keeps latency and power consumption low (nominally 0.1 W) and contributes to long service life and low failure rates. The cable uses industry-standard connector types compatible with many server and storage controllers and offers a cost-effective connectivity solution for professional environments.
Suitable for
 Connecting SAS HDDs and SSDs to controllers and expanders in rack-mounted servers
 Interconnecting storage enclosures and adjacent rack equipment
 Short-distance, high-density data center interconnects where MiniSAS is required
Key specifications
 Cable length: 0.5 m
 Connector type: SFF-8088 male to SFF-8088 male (MiniSAS hybrid configuration)
 Supported protocols: SAS (3 Gb/s and 6 Gb/s compatible)
 Cable type: MiniSAS twinax hybrid (copper twinax for short-range high-speed links)
 Power consumption: low (approx. 0.1 W passive operation)
 Design: slim HD connector for high-density rack installations
How to use
Install the cable by aligning the SFF-8088 connectors with the corresponding ports on your server, controller or storage enclosure and push until the connector seats firmly. Use the 0.5 m length for short, direct connections inside or between adjacent racks; avoid sharp bends and excessive pulling force. As a passive cable it relies on the connected devices to provide signal conditioning and protocol support, so ensure connected hardware supports MiniSAS/SAS 3 Gb/s or 6 Gb/s as required.
Usage recommendations
For optimal performance, route the cable away from sources of electromagnetic interference, maintain bend radii recommended by the device manufacturer, and confirm controller firmware and port configuration match the SAS speeds in use. Use this cable for short-range, high-density interconnects and replace if physical damage or connector wear is observed.
