BlueOptics AOC-Q-Q-100G-3M-BO InfiniBand fibre optic cable QSFP28 3m Male/Male

The BlueOptics AOC-Q-Q-100G-3M-BO InfiniBand fibre optic cable QSFP28 3m Male/Male is a 3-metre active optical cable designed for high-speed 100G interconnects. It uses QSFP28 interfaces on both ends to provide a direct, low-latency connection between network devices. The cable is intended for short-reach links inside racks and between adjacent racks in data centres, server rooms and high-performance computing environments.

Advantages

This QSFP28 active optical cable supports 100 Gigabit throughput with reduced electromagnetic interference compared with copper alternatives. The male-to-male QSFP28 connectors offer plug-and-play compatibility with standard QSFP28 ports and maintain signal integrity over the 3 metre length. The optical link design reduces heat generation in dense installations and enables compact cable routing while preserving high data rates and low latency.

Suitable for

• High-density switch-to-switch connections in data centres
• Server-to-switch and server-to-direct-attach links in rack deployments
• Storage array interconnects and backbone aggregation
• High-performance computing clusters requiring low-latency links

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Data rate: 100 Gbit/s
• Length: 3 metres
• Cable type: Active optical cable (AOC)
• Signal: InfiniBand compatible, suitable for Ethernet 100G links where supported
• Application: Short-reach interconnects inside racks and between adjacent racks

How to use

Install the cable by inserting each QSFP28 connector into the corresponding QSFP28 port on the devices, ensuring the latch engages to secure the connection. Verify link status LEDs or management interfaces on connected equipment to confirm successful negotiation at 100G. For upgrades or replacements, power down equipment only if required by the vendor; most devices support hot-plugging of QSFP28 modules and cables.

Recommendations

Route the cable to avoid sharp bends and maintain the manufacturer’s minimum bend radius. Use appropriate cable management in racks to reduce strain on connectors. Ensure firmware and driver support for QSFP28 100G links on the connected devices and check compatibility with switch and server vendor documentation prior to deployment.
