BlueOptics Q28-AOC-30M-MT-BO InfiniBand fibre optic cable 30m QSFP28 Male

The BlueOptics Q28-AOC-30M-MT-BO InfiniBand fibre optic cable 30m QSFP28 Male is a 30-metre active optical cable designed for high-speed interconnects in data centers and high-performance computing environments. It uses QSFP28 male connectors at both ends to support InfiniBand and other 100Gbps-class links, providing a low-latency, electrically isolated connection suitable for rack-to-rack and intra-rack cabling. The cable's length and connector type make it suitable for deployments where length, signal integrity and easy plug-and-play installation are required.

Advantages

This 30m active optical cable offers high bandwidth and signal integrity over longer distances than equivalent copper solutions, while reducing electromagnetic interference due to its optical transmission. The QSFP28 male connectors provide standardized compatibility with ports that accept QSFP28 modules, enabling straightforward insertion and removal. The cable's flexibility and fixed-length design eliminate the need for transceivers and simplify inventory management in dense networking setups.

Suitable for

• Rack-to-rack connections in data centers
• High-performance computing clusters and InfiniBand fabrics
• Network switches and servers with QSFP28 ports
• Short to medium distance backbone links where low latency is required

Key specifications

• Type: Active optical cable (AOC)
• Connector type: QSFP28 male to QSFP28 male
• Length: 30 metres
• Supported protocol classes: InfiniBand and 100Gbps-class links
• Transmission medium: Multimode optical fiber with integrated transceivers
• Typical use case: Rack-to-rack and intra-rack high-speed links

How to use

To install, align each QSFP28 male connector with the corresponding QSFP28 port on network equipment, insert until the latch engages, and ensure a secure fit. Verify link status on connected devices and confirm negotiated speed and lane configuration via device management interfaces. Handle the cable by the connector housings when plugging or unplugging and route the cable to avoid tight bends; follow equipment vendor guidance for bend radius. No separate transceivers are required because the optical transceivers are integrated into the cable ends.

Recommendations

Store and route the cable to avoid sharp bends and mechanical stress; maintain the manufacturer-recommended minimum bend radius. Use in environments matching the equipment's operating temperature and humidity ranges and ensure QSFP28 ports are compatible with AOC cables. When connecting critical links, verify firmware and driver compatibility on connected devices to ensure full performance.
