BlueOptics CBL-0310-030-BO InfiniBand/fibre optic cable 30 m QSFP

The BlueOptics CBL-0310-030-BO InfiniBand/fibre optic cable 30 m QSFP is a 30‑metre active optical cable designed for high‑speed links between QSFP ports. It uses QSFP male connectors on both ends and multi‑mode fibre with integrated optical transmitters and receivers to support short‑reach 40 G data transmission over a single cable. The construction follows common QSFP AOC conventions for compatibility with network switches, storage systems and compute platforms that accept QSFP active optical connections.

Advantages

This 30 m QSFP active optical cable delivers low latency and stable 40 G throughput over multi‑mode fibre while reducing electromagnetic interference compared with copper alternatives. The integrated transceivers on each end simplify installation by presenting a standard QSFP interface and enable reliable signal integrity across the full 30 m length. The cable’s design supports high port density environments and helps maintain predictable performance for InfiniBand, Ethernet and Fibre Channel over Ethernet applications.

Suitable for

• Data centre uplinks between QSFP ports
• High‑performance computing clusters using InfiniBand or 40 G links
• Interconnects between switches, routers and storage arrays
• Short‑reach 40 G Ethernet and Fibre Channel over Ethernet connections

Key specifications

• Connector type: QSFP male to QSFP male
• Length: 30 metres
• Transmission medium: multi‑mode fibre with active optical transceivers
• Supported data rate: up to 40 Gbit/s
• Typical applications: InfiniBand, 40G Ethernet, Fibre Channel over Ethernet
• Form factor: active optical cable (AOC) with integrated transmitter and receiver at each end

How to use

Connect each QSFP male end into compatible QSFP ports on the devices to be linked, ensuring the port supports active optical QSFP modules and the intended 40 G protocol. Verify link negotiation and port status on both devices after insertion. Route the cable to avoid tight bends and mechanical strain; secure it using existing cable management to prevent stress on the connectors. If a link does not establish, check device compatibility and port settings, then reseat the cable.

Usage recommendations

For reliable operation, maintain bend radii above the manufacturer’s minimum for multi‑mode AOC assemblies, use proper cable routing to limit connector strain, and confirm that connected devices support QSFP active optical links and the chosen protocol (InfiniBand, 40G Ethernet or FCoE).
