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

The BlueOptics Q28-AOC-30M-MA-BO is a 30-metre active optical cable with QSFP28 male connectors on both ends, designed for InfiniBand and high-speed fibre optic links. It provides a single-cable solution for up to 100Gbps class connections between servers, switches and host adapters. The cable's 30m reach supports flexible equipment placement in data centres and high-performance computing racks while reducing electromagnetic interference common to copper links.

Advantages

The QSFP28 male/male active optical design delivers high bandwidth with low latency and improved signal integrity over longer distances compared with copper alternatives. The fibre construction reduces susceptibility to EMI and cross-talk and helps maintain stable throughput for demanding parallel data transfers. Its plug-and-play form factor simplifies deployment without additional transceivers, and the longer 30-metre length offers greater layout flexibility for rack-to-rack and row-to-row connectivity.

Suitable for

• Server-to-switch and switch-to-switch connections in data centres
• High-performance computing clusters and InfiniBand fabrics
• Network expansion and flexible rack placement
• Latency-sensitive applications such as storage and virtualization backplanes

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Cable type: Active optical cable (AOC)
• Supported protocol families: InfiniBand and compatible 100Gb class Ethernet links
• Length: 30 metres
• Typical bandwidth: up to 100 Gbps aggregate (QSFP28 class)
• Latency: low, suitable for latency-sensitive interconnects
• Interference immunity: fibre-based, immune to electromagnetic interference

How to use

Connect each QSFP28 male plug into the corresponding QSFP28 port on your devices, ensuring secure seating until the connector latch engages. The active optical cable is recognized by most compatible host adapters and switches without separate transceivers; verify port compatibility and link settings in your equipment's management interface. Route the cable to avoid tight bends and maintain the manufacturer's recommended minimum bend radius for optical fibres. For multi-vendor environments check link negotiation and firmware support to ensure full speed and feature compatibility.

Recommendations

Use this cable for rack-to-rack or row-to-row connections where a 30 m reach and high data throughput are required. Maintain gentle routing with no sharp bends, keep connectors clean and capped when not in use, and confirm device compatibility for QSFP28 interfaces and supported protocols before installation.
