QNAP CAB-DAC15M-SFP28 InfiniBand/fibre optic cable 1.5 m QSFP28 Black

The QNAP CAB-DAC15M-SFP28 is a 1.5 m InfiniBand/fibre optic direct-attach cable with QSFP28 connectors on both ends, designed for high-speed connections in data center and enterprise networking environments. It supports low-latency, high-throughput data transmission for server-to-switch and switch-to-switch links where reliable, high-bandwidth interconnects are required. The cable's construction focuses on stable signal integrity and durability to maintain consistent performance under continuous use.

Advantages

The CAB-DAC15M-SFP28 combines a compact 1.5 m length with QSFP28 connectivity to provide a short-reach, high-performance link that reduces latency and signal loss compared with longer or improperly matched cables. Its design is compatible with InfiniBand and fibre optic environments, offering consistent throughput for demanding workloads. The cable's build quality contributes to long-term reliability and stable connections in rack and chassis installations.

Suitable for

• Server-to-switch connections in data centers
• Switch-to-switch high-bandwidth links
• High-performance computing (HPC) clusters requiring low latency
• Storage network interconnects and SAN environments

How to use

Install the CAB-DAC15M-SFP28 by aligning each QSFP28 connector with the corresponding port on your networking device and inserting it until it seats securely. Ensure devices are powered down or follow hot-plugging procedures recommended by the device manufacturer when connecting or disconnecting in live systems. Verify link status and speed through your switch or host adapter management interface to confirm the connection is active and operating at expected bandwidth and latency levels.

Recommendations

Place the cable to avoid sharp bends and mechanical stress; maintain the minimum bend radius recommended for QSFP28 connectors. Use appropriate port mappings and cable management in racks to prevent strain on the connectors. Confirm compatibility with the specific InfiniBand or fibre optic ports on your equipment and consult device documentation if any link configuration is required.
