BlueOptics Q28-AOC-30M-LE-BO InfiniBand fibre optic cable 30m QSFP28 Male/Male

The BlueOptics Q28-AOC-30M-LE-BO InfiniBand fibre optic cable 30m QSFP28 Male/Male is a 30-metre active optical cable engineered for high-throughput, low-latency connections in data centers and enterprise networks. With QSFP28 male connectors at both ends, this cable supports multi-lane, high-bandwidth links suitable for modern InfiniBand and 100GbE infrastructures. The design focuses on reliable long-reach transmission over 30 metres while minimizing electromagnetic interference and maintaining signal integrity.

Advantages

This fibre optic cable delivers stable, high-speed data transfer across 30 metres using QSFP28 interfaces, enabling efficient inter-rack and intra-rack connectivity. As an active optical cable, it offers lower power consumption and reduced heat generation compared with some copper alternatives, and provides consistent performance over the specified distance. The QSFP28 Male/Male termination ensures compatibility with switches, servers and host adapters that accept QSFP28 connectors.

Suitable for

• High-performance computing clusters and InfiniBand fabrics
• Data center switch-to-switch and switch-to-server links
• 100GbE or multi-lane high-bandwidth connections requiring 30 m reach
• Environments where low latency and signal integrity are essential

Key specifications

• Cable type: Active optical cable (AOC)
• Connector type: QSFP28 Male to QSFP28 Male
• Length: 30 metres
• Supported protocols: InfiniBand and high-speed Ethernet multi-lane links
• Signal medium: Fibre optic (optical) transmission
• Typical usage: Interconnects for racks, servers, switches and host adapters

How to use

Install the cable by aligning each QSFP28 male connector with the corresponding QSFP28 port on your devices and inserting until the connector latches. Confirm that connected devices recognize the link and that status LEDs indicate an active connection. For best results, avoid tight bends and excessive twisting; route the cable along established cable management paths and secure with ties that do not compress the cable. When disconnecting, release the latch before pulling the connector straight out to prevent connector damage.

Recommendations

Use the cable in climate-controlled rack environments and avoid exposure to moisture, dust or direct mechanical stress. Maintain minimum bend radius consistent with manufacturer guidance for active optical cables and check device firmware or port settings for compatibility with QSFP28 AOC modules. Regularly inspect connectors for contamination and clean with appropriate fibre-optic cleaning tools if necessary.
