BlueOptics Q28-AOC-2M-FR-BO InfiniBand/fibre optic cable 2m QSFP28 Male/Male

The BlueOptics Q28-AOC-2M-FR-BO InfiniBand/fibre optic cable is a 2 m active optical cable with QSFP28 male connectors on both ends, built for high-throughput, low-latency links in data centre and high-performance computing environments. This cable supports high-speed serial data transmission and is intended for direct interconnects between compatible QSFP28 ports, delivering the physical layer connection required for InfiniBand or other high-speed networking protocols.

Advantages

This 2 m QSFP28 active optical cable provides a compact and lightweight alternative to traditional copper or transceiver-plus-patch-cord combinations, reducing rack congestion and easing cable management. The optical construction delivers electrical isolation and improved signal integrity over longer distances compared with copper direct attach cables. With QSFP28 male-to-male terminations, the cable enables straightforward connections between switches, host adapters and other QSFP28-equipped devices while maintaining the bandwidth characteristics expected from modern 100 Gbps-class interfaces.

Suitable for

• Interconnects between switches and routers in data centres
• Connections between servers and InfiniBand host channel adapters
• High-performance computing clusters requiring low-latency links
• Top-of-rack and end-of-row network cabling

Key specifications

• Cable type: active optical cable (AOC) designed for InfiniBand and similar high-speed networks
• Connector type: QSFP28 male on both ends
• Length: 2 metres
• Data rate: suitable for 100 Gbps-class QSFP28 links (support depends on system compatibility)
• Transmission medium: multimode optical signalling implemented within an integrated AOC assembly
• Form factor: compact QSFP28 profile for high-density installations

How to use

Install the BlueOptics QSFP28 AOC by inserting each QSFP28 connector into the corresponding port on your network equipment until the connector latches. Ensure both ends are fully seated and that the host devices support QSFP28 optical AOCs. After physical installation, verify link status in the device management interface and configure network parameters as required by your topology and protocol. For safe removal, use the connector's release mechanism where present and avoid bending or pulling the cable by the optical assembly.

Recommendations

Allow sufficient bend radius and avoid routing the cable around sharp edges; maintain a tidy cable path to preserve optical performance. Confirm firmware and driver compatibility for QSFP28 AOCs on your switches or host adapters, and use manufacturer guidance for interoperable configurations. For optimal thermal and performance behaviour, install AOCs in accordance with equipment vendor spacing and airflow recommendations.
