BlueOptics QSFP-AOC-3M-DL-BO InfiniBand/fibre optic cable 3m Male/Male

The BlueOptics QSFP-AOC-3M-DL-BO is a 3‑metre active optical cable with QSFP connectors on both ends, intended for InfiniBand and fibre‑optic network links. This male/male AOC supports high‑speed serial data transmission between switches, servers and adapters in data centre and high‑performance computing environments. The cable’s construction combines optical fibres with integrated transceivers to deliver low latency and electrical isolation over the 3 m link length.

Advantages

The active optical design provides high bandwidth with reduced electromagnetic interference and lower power dissipation compared with equivalent copper direct attach solutions. A 3 m length offers a balance between reach and rack density, enabling flexible placements within server racks or between adjacent cabinets. Native QSFP connectivity on both ends ensures straightforward plug‑and‑play installation with compatible QSFP ports and preserves signal integrity for demanding InfiniBand workloads.

Suitable for

• High‑performance computing clusters and GPU interconnects
• Top‑of‑rack and end‑of‑row switch connections
• Server‑to‑switch or switch‑to‑switch links requiring low latency
• Data centre fabric and storage network interconnects

Key specifications

• Connector type: QSFP male to QSFP male
• Cable type: Active optical cable (AOC)
• Length: 3 metres
• Application: InfiniBand and fibre‑optic high‑speed links
• Latency: low (optical transmission)
• Suitable environment: data centre and networking racks

How to use

Insert each QSFP connector into a compatible QSFP port until the latch engages. Ensure devices are powered down or follow hot‑swap guidance from your hardware vendor if connecting live. After physical installation, verify link status and speed through the host or switch management interface and confirm that InfiniBand or fibre link parameters are negotiated correctly. Handle the cable by the connector housings and avoid sharp bends; maintain the minimum bend radius recommended by the equipment manufacturer to preserve optical performance.

Recommendations

Use the BlueOptics QSFP-AOC-3M-DL-BO for short‑reach, high‑throughput connections inside racks or between adjacent racks. Avoid exposing the cable to excessive mechanical stress, liquid, or temperatures outside standard data centre operating ranges. For mixed media or longer links, consider suitable transceiver and fibre options instead of AOC assemblies.
