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

The BlueOptics Q28-AOC-3M-SP-BO InfiniBand/fibre optic cable 3m QSFP28 Male/Male is a 3‑meter active optical cable engineered for high‑speed, low‑latency data connections between QSFP28 ports. It provides a direct, factory‑terminated connection suitable for short‑reach links in data centers, server racks, and networking equipment where reliable 100Gbps class performance is required. The male‑to‑male QSFP28 connectors enable plug‑and‑play installation without additional transceivers.

Advantages

This cable combines the electrical simplicity of QSFP28 interfaces with the optical performance of an active optical cable, offering stable high‑bandwidth transmission and reduced electromagnetic interference compared with copper alternatives. Its fixed 3 m length simplifies cable management in rack environments and eliminates the need for separate optics and patch cords. The plug‑and‑play QSFP28 male connectors support straightforward deployment and minimal configuration effort.

Suitable for

• Connecting QSFP28 ports in data center switches and routers
• Linking servers and storage systems requiring 100Gbps class bandwidth
• Short‑reach intra‑rack and inter‑rack connections up to 3 meters
• High‑performance computing and InfiniBand environments

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Length: 3 meters
• Medium: Active optical cable (AOC)
• Supported interface: InfiniBand and fibre optic high‑speed links
• Data rate class: 100Gbps class connectivity over QSFP28
• Low latency design suitable for high‑performance networking

How to use

Ensure both devices have compatible QSFP28 ports and support active optical connections. Align the QSFP28 male connector with the port, insert until the latch engages, and verify link LEDs or management interfaces indicate an active connection. No external optical transceivers are required. To remove, press the QSFP28 latch mechanism and withdraw the connector carefully to avoid stressing the cable or port.

Recommendations

Route the cable to avoid tight bends and maintain the manufacturer’s minimum bend radius; secure it with appropriate cable management to prevent strain on connectors. Use this 3 m QSFP28 AOC for short‑reach high‑performance links inside racks or between adjacent racks, and confirm host and switch firmware compatibility if link negotiation issues occur.
