## Long description

The BlueOptics X66211A-5-BL InfiniBand fibre optic cable 5 m QSFP28 is a high-speed interconnect designed for short-reach links in data centre and HPC environments. This 5-metre cable features QSFP28 connectivity and is intended for reliable, low-latency transmission between switches, servers and storage appliances supporting InfiniBand and other 100G-class protocols. The design focuses on stable signal integrity and physical compatibility with standard QSFP28 ports.
Advantages
The cable offers a standardized QSFP28 interface for 100G-class data rates and is suitable for installations requiring short, direct connections with minimal latency. Its 5 m length is appropriate for intra-rack and adjacent-rack cabling, simplifying cable management in dense equipment racks. Constructed to meet common industry mechanical and electrical expectations, it provides predictable performance for InfiniBand, Ethernet and related high-speed protocols.
Suitable for
Intra-rack and adjacent-rack high-speed connections
Links between QSFP28-equipped switches and servers
High-performance computing clusters and data centre fabrics
100G InfiniBand and Ethernet short-reach links
Key specifications
Cable type: QSFP28 to QSFP28 high-speed fibre optic interconnect
Supported data rates: up to 100 Gbit/s per link (protocol dependent)
Length: 5 metres
Connector form factor: QSFP28
Intended use: short-reach data centre and HPC interconnects
How to use
Inspect both QSFP28 ports and cable ends for damage or debris before installation. Align the QSFP28 module with the port guide rails and insert the connector straight into the port until it seats. For removal, release any latch or retention mechanism and withdraw the connector evenly. Route the cable to avoid sharp bends, kinks or contact with hot surfaces, maintaining the minimum bend radius recommended by equipment manufacturers. Ensure connected devices are configured for the appropriate InfiniBand or Ethernet settings and verify link status after installation.
Usage recommendations
Use this 5 m QSFP28 cable for short-distance connections inside racks or between adjacent racks where a compact, low-latency link is required. Avoid exceeding the cable's intended use area and follow vendor guidelines for QSFP28 port handling and ESD precautions. Regularly check link status and physical condition during scheduled maintenance to ensure continued performance.
