BlueOptics Q28-AOC-2M-LE-BO InfiniBand fibre optic cable 2m QSFP28 Male/Male

The BlueOptics Q28-AOC-2M-LE-BO InfiniBand fibre optic cable is a 2-meter active optical cable with QSFP28 connectors on both ends. It provides a compact, low-latency link for high-bandwidth environments such as data centers and high-performance computing clusters. The male-to-male QSFP28 terminations make it compatible with equipment that accepts QSFP28 ports and designed to support InfiniBand protocols and high-rate Ethernet interconnects.

Advantages

This active optical cable offers high data throughput with reduced electromagnetic interference and lower power consumption compared with equivalent copper alternatives. The short 2 m length minimizes signal loss while the integrated transceivers enable straightforward plug-and-play deployment without separate SFP/QSFP modules. Its QSFP28 form factor supports dense port layouts and simplifies cabling in rack and blade environments.

Suitable for

• Interconnecting switches, servers and storage in data centers
• High-performance computing (HPC) clusters and InfiniBand networks
• Low-latency links in hyperscale and enterprise networks
• Short-reach connections inside racks and between adjacent racks

Key specifications

• Cable type: Active optical cable (AOC)
• Connector type: QSFP28 male to QSFP28 male
• Length: 2 meters
• Applications: InfiniBand and high-rate Ethernet interconnects
• Latency: Low-latency design suitable for performance-sensitive traffic
• EMI immunity: Optical transmission eliminates electromagnetic interference

How to use

Connect the QSFP28 male connectors to the corresponding QSFP28 ports on your devices, ensuring each connector is fully inserted and latched according to the equipment manufacturer’s instructions. The integrated optical transceivers are hot-pluggable; verify link status LEDs on both devices to confirm negotiation and link activation. For best performance, avoid tight bends in the cable and ensure proper airflow around connected equipment.

Recommendations

Use this 2 m QSFP28 AOC for short-reach, high-bandwidth links inside racks or between adjacent racks. Keep bend radius within manufacturer guidelines, maintain clean connector interfaces, and follow equipment compatibility lists to ensure supported data rates and protocols.
