InfiniBand/fibre optic cable BlueOptics JL271A-BL 1 m QSFP28 Black

The BlueOptics JL271A-BL is a 1 m InfiniBand/fibre optic cable with QSFP28 connectors on both ends, designed for high-speed data transfer in demanding networking environments. The cable supports reliable, low-latency connectivity suitable for data centers, high-performance computing clusters and enterprise switching systems. The QSFP28 interface and multi-mode fibre construction deliver the bandwidth and signal integrity required for 100 Gigabit/s class links while maintaining a compact, robust form factor.

Advantages

This 1 m cable offers high throughput and low insertion loss, providing consistent performance for short-reach connections between QSFP28 ports. The symmetrical QSFP28 connectors simplify installation and reduce the risk of mismatched terminations. Designed for use in rack and cabinet environments, the cable features a flexible jacket that eases cable management and routing in dense setups while maintaining mechanical durability.

Suitable for

• Interconnecting QSFP28 ports in data center switches and routers
• Short-reach InfiniBand or 100 GbE links between servers and storage systems
• High-performance computing (HPC) cluster node connections
• Top-of-rack and end-of-row cabling in enterprise and carrier networks

Key specifications

• Cable length: 1 m
• Connector type: QSFP28 to QSFP28
• Application: InfiniBand and fibre optic high-speed links
• Data rate class: suitable for 100 Gigabit/s class connections
• Cable colour: black
• Design: compact, short-reach multi-mode optical assembly

How to use

Connect each QSFP28 connector to the corresponding QSFP28 port on your network devices, ensuring connectors are fully seated and retention latches engage where present. For optimal performance, avoid sharp bends and excessive pulling on the cable; maintain recommended bend radii for fibre optic assemblies. Verify link status on connected devices and run any required diagnostics or link tests after installation to confirm signal integrity and data throughput.

Recommendations

Use this short-reach QSFP28 cable in controlled rack or cabinet environments for links up to 1 m. Keep the cable free of tight bends and secure it with appropriate cable management accessories to prevent stress on connectors. For longer runs or outdoor installations, select a fibre solution engineered for extended reach or environmental exposure.
