InfiniBand/fibre optic cable BlueOptics X4DACBL5 5 m QSFP 4xSFP+ Black

The BlueOptics X4DACBL5 is a 5 m InfiniBand/fibre optic cable with a QSFP plug on one end and four SFP+ plugs on the other, designed for high-speed data transmission between network devices. This cable supports aggregated links through the QSFP to 4xSFP+ interface and is intended for use in data centre racks, switches and servers where compact, direct-attach cabling is required. The male connectors provide straightforward insertion and secure mating with compatible ports.

Advantages

The cable offers a compact, factory-terminated connection that reduces assembly time and cable clutter. Its 5 m length balances reach and signal integrity for short to medium interconnects. The QSFP to 4xSFP+ configuration enables a single QSFP port to connect to multiple SFP+ ports without additional breakout modules. The construction is optimized for consistent transmission performance and stable mechanical mating in dense networking environments.

Suitable for

• High-speed links between QSFP-enabled switches and multiple SFP+ devices
• Top-of-rack and server-to-switch interconnects in data centres
• InfiniBand fabric connections requiring compact direct-attach solutions
• Environments needing reliable short-range optical or direct-attach connectivity

Key specifications

• Cable length: 5 metres
• Connector type (one end): QSFP male
• Connector type (other end): 4 × SFP+ male
• Colour: black
• Application: high-speed data centre and networking interconnects

How to use

Inspect both device ports and the cable connectors for dust or damage before installation. Align the QSFP connector with the QSFP port and insert until it seats securely; then connect the four SFP+ plugs into corresponding SFP+ ports. Ensure that connected devices are powered down or configured according to vendor guidance if hot-plugging is not supported. After connection, verify link status and data rates through device management interfaces or LED indicators.

Recommendations

For optimal performance, avoid tight bends and excessive tension on the cable; maintain manufacturer-recommended bend radius and route the cable away from sources of electromagnetic interference. Use in compatible QSFP and SFP+ ports and confirm that connected devices support the intended aggregated link configuration.
