BlueOptics Q28-AOC-15M-NK-BO InfiniBand/fibre optic cable QSFP28 15m Male/Male

The BlueOptics Q28-AOC-15M-NK-BO InfiniBand/fibre optic cable QSFP28 15m Male/Male is a 15-metre active optical cable designed for high-bandwidth, low-latency connections in data centres and network racks. Equipped with QSFP28 connectors on both ends, this cable supports high-speed serial links between switches, servers and storage nodes where InfiniBand or compatible optical QSFP28 interfaces are used. Its 15 m length provides flexibility for mid-rack and cross-rack interconnects while maintaining signal integrity typical of active optical solutions.

Advantages

The active optical construction delivers reduced electromagnetic interference and lower power consumption at longer distances compared with equivalent copper DACs, while QSFP28 interfaces enable up to 100 Gbps class links depending on the connected equipment. As a pre-terminated male-to-male cable, it simplifies installation and reduces deployment time by avoiding field terminations. The 15 m reach offers balance between flexibility and performance for typical data centre layouts.

Suitable for

• High-speed server-to-switch connections in data centres
• Switch-to-switch or spine-to-leaf interconnects requiring QSFP28 ports
• Storage system links that use InfiniBand or compatible optical QSFP28 interfaces
• Cross-rack connections where a 15 m active optical link is needed

Key specifications

• Cable type: Active optical cable (AOC)
• Connector type: QSFP28 male to QSFP28 male
• Length: 15 metres
• Supported link technology: InfiniBand / optical QSFP28-compatible high-speed links
• Typical use: Data centre interconnects, server, switch and storage links
• Signal characteristics: Low latency, high bandwidth suitable for 100 Gbps-class links (dependent on host hardware)

How to use

Install the cable by inserting each QSFP28 male connector into the corresponding QSFP28 port on your network devices until the latch engages. Ensure both ends are compatible with the host interfaces and that devices are powered down or follow hot-plug guidelines provided by the device manufacturer if available. Route the cable to avoid sharp bends and mechanical stress; observe minimum bend radius recommendations for active optical cables. After connection, verify link status and speed in the host equipment’s management interface.

Recommendations

Use the cable within typical data centre ambient temperature ranges, avoid exposure to liquids and mechanical strain, and keep connectors capped when not in use. Confirm compatibility with your devices’ QSFP28 and InfiniBand firmware and transceiver settings to achieve optimal performance.
