BlueOptics Q9S69A-BO InfiniBand/fibre optic cable 5 m QSFP 4xSFP+ Aqua

The BlueOptics Q9S69A-BO InfiniBand/fibre optic cable 5 m QSFP 4xSFP+ Aqua is a pre-assembled active optical cable (AOC) that links a QSFP port to four SFP+ ports over multi-mode fiber. With a 5 meter length and male/male QSFP to 4xSFP+ termination, this cable supports 40GBASE-SR4-class transmission and is intended for high-density data centre and networking environments where a compact, low-latency 40 Gbps interconnect is required. The aqua jacket identifies the multimode grade and simplifies traceability in cabling runs.

Advantages

The cable integrates transmitter and receiver electronics on each end to deliver optical signals over multimode fiber without separate transceivers, offering a ready-to-install QSFP-to-4xSFP+ solution. Compliance with MSA-style QSFP and SFP+ pinouts and adherence to industry SR4 multimode optics parameters enable compatibility with a wide range of switches and storage hardware that support 40G QSFP and 10G SFP+ endpoints. Built-in digital diagnostics (DDM/DOM) provide real-time monitoring of supply voltage, laser bias current, optical output/input power and temperature to simplify troubleshooting and maintenance.

Suitable for

• 40 Gbps to 4×10 Gbps breakout connections between switches and line cards
• High-density data centre uplinks and top-of-rack aggregation
• Interconnects between storage arrays and switches supporting SFP+ and QSFP ports
• Low-latency InfiniBand or Ethernet links in compute clusters

Key specifications

• Length: 5 metres
• Connector type: QSFP (one end) to 4×SFP+ (other end)
• Data rate: supports 40GBASE-SR4-class 40 Gbps aggregated throughput (4×10 Gbps lanes)
• Medium: multimode fiber AOC (aqua jacket)
• Integrated optics: active transmitter and receiver on both ends
• Digital diagnostics: DDM/DOM monitoring compliant with MSA SFF-8472
• Application protocols: Ethernet, Fibre Channel over Ethernet, InfiniBand compatible

How to use

Install the BlueOptics QSFP-to-4xSFP+ AOC by inserting the QSFP plug into the host QSFP port and seating the four SFP+ plugs into the target SFP+ ports. Ensure connectors are fully engaged and latched where applicable. No separate transceivers, patching or fiber termination is required. Verify that the host devices support QSFP-to-4xSFP+ breakout operation and that the firmware or port configuration is set for the intended lane mapping and speed (for example 40G native or 4×10G breakout). If your hardware supports DDM/DOM, use management tools to read real-time diagnostics for link validation and monitoring.

Usage recommendations

Route the cable to avoid sharp bends and mechanical strain; adhere to the manufacturer’s minimum bend radius for multimode AOC assemblies. Confirm device compatibility with QSFP-to-4×SFP+ breakout modes before deployment, and check that power and temperature thresholds reported by DDM/DOM remain within acceptable ranges. For predictable performance in data centres, label both ends and maintain clear paths in patching panels and trays.
