SAS-kaapeli BlueOptics BLIS4343-50CM 0,5 m 12 Gbit/s

The BlueOptics BLIS4343-50CM is a 0.5 m MiniSAS-HD (SFF-8643) twinaxial SAS cable designed for internal connections in servers, storage enclosures and SANs. It supports SAS protocol speeds up to 12 Gbit/s and is suitable for short-distance, high-bandwidth links in data center rack environments. The cable is passive, RoHS-compliant and built from quality components to provide reliable, low-skew signal transmission for SAS devices such as hard drives and RAID controllers.

Advantages

This 50 cm MiniSAS-HD cable offers high bandwidth capability with support for 6 Gbit/s and 12 Gbit/s SAS protocols while maintaining low signal skew thanks to its foldable twinaxial design. As a passive cable it does not require active circuitry, which reduces failure points and production cost. Components from established manufacturers and a design targeting long lifetime contribute to reduced maintenance and high availability in professional rack installations.

Suitable for

• Internal connections between servers, RAID controllers and SAS backplanes
• Short-distance links inside data center racks and storage enclosures
• Connecting SAS hard drives, SSDs and storage arrays supporting MiniSAS-HD
• High-density installations where compact SFF-8643 connectors are required

Key specifications

• Cable length: 0.5 m (50 cm)
• Connector type: MiniSAS-HD (SFF-8643) on both ends
• Data transfer rate: up to 12 Gbit/s (supports 6 Gbit/s and 12 Gbit/s SAS)
• Cable type: foldable low-skew twinaxial (passive twinax)
• Use case: internal rack / chassis SAS connections
• Compliance: RoHS compliant
• Design focus: low skew, high bandwidth, passive operation

How to use

Connect one MiniSAS-HD (SFF-8643) connector to the SAS port on a host adapter, RAID controller or server backplane and the other connector to the target device such as a SAS backplane, storage enclosure or drive carrier. Ensure both ends are fully seated to avoid intermittent connections. Because the cable is passive, verify that connected hardware supports passive MiniSAS-HD twinaxial cables at the intended data rate (6 Gb/s or 12 Gb/s). Route the cable in the rack to avoid sharp bends and mechanical strain on connectors.

Recommendations

For optimal performance, use this BlueOptics 0.5 m MiniSAS-HD cable for short internal runs within racks or chassis. Avoid tight bending radii and keep the cable away from high-power or noisy signal sources. Confirm compatibility with your RAID controller or HBA for passive twinaxial cables and select appropriate lengths to maintain tidy routing and airflow in the server cabinet.
