BlueOptics Q28-AOC-3M-CI-BO InfiniBand/fibre optic cable 3m QSFP28 Male/Male

The BlueOptics Q28-AOC-3M-CI-BO InfiniBand/fibre optic cable 3m QSFP28 Male/Male is a 3-meter active optical cable designed to provide high-speed, low-latency connectivity between QSFP28 ports. Intended for use in data centers and high-performance computing environments, this cable supports short-reach links where reliable 100Gbps-class connections are required. The male-to-male QSFP28 terminations enable direct connection between compatible network adapters, switches and storage devices without additional transceivers.

Advantages

This active optical cable offers the bandwidth and signal integrity expected from QSFP28 class links while maintaining reduced power consumption compared with equivalent electrical copper assemblies. The 3 m length provides flexibility for rack-to-rack or within-rack connections while limiting excess cable slack. The plug-and-play QSFP28 male connectors simplify installation and replacement in dense server and switch configurations.

Suitable for

• Interconnects between QSFP28 ports on switches and network adapters
• Short-reach links in data center top-of-rack and middle-of-row deployments
• High-performance computing clusters and storage fabric connections
• Environments requiring low-latency, high-bandwidth optical links

Key specifications

• Cable type: Active optical cable (AOC)
• Connector type: QSFP28 male to QSFP28 male
• Length: 3 metres
• Supported interface: InfiniBand and compatible fibre optic QSFP28 links
• Typical use: Short-reach 100Gbps-class connections

How to use

Ensure both endpoints support QSFP28 connections and that ports are powered off or follow hot-plug guidelines of your equipment. Align the QSFP28 male connectors with the device port and insert until the latch engages. If the host or switch requires driver or firmware-level recognition, verify link status through management software or LEDs after insertion. For removal, release the connector latch and withdraw the cable straight out to avoid damaging ports.

Recommendations

Route the cable to avoid sharp bends and maintain the manufacturer’s minimum bend radius. Keep connectors free of dust and inspect ports before insertion. Use in temperature-controlled data centre environments and follow ESD precautions when handling.
