BlueOptics 49Y7888-LE cable de fibra óptica InfiniBand 5 m QSFP 4xSFP+ negro

The BlueOptics 49Y7888-LE InfiniBand/fibre optic cable 5 m QSFP 4xSFP+ Black is a multi-lane optical cable engineered for high-speed interconnects in data center and enterprise networking environments. With a 5 metre length and a QSFP-to-4xSFP+ configuration, the cable supports aggregating four 10 Gb/s lanes into a single QSFP interface for low-latency, high-throughput links between switches, routers and servers. The cable is designed for male QSFP and SFP+ terminations to ensure secure mechanical connections and reliable signal transmission over short to medium distances.

Advantages

This fibre optic assembly provides consolidated connectivity that simplifies cabling runs and reduces the need for separate transceivers. Its QSFP to 4xSFP+ breakout format enables flexible port mapping and easy integration with existing SFP+ ports while maintaining the performance characteristics required for InfiniBand and 10 Gigabit Ethernet links. The 5 m length balances reach and manageability in rack and cabinet deployments, and the black jacket offers a neutral appearance suitable for standard data centre cabling schemes.

Suitable for

• Connecting QSFP-enabled switches to multiple SFP+ ports on servers or aggregation devices
• InfiniBand or 10 GbE breakout links in top-of-rack and end-of-row configurations
• Short- to medium-reach optical interconnects within racks and between adjacent cabinets

Key specifications

• Cable length: 5 metres
• Connector type: QSFP to 4 × SFP+
• Supported link types: InfiniBand and 10 Gigabit Ethernet (breakout)
• Polarity and termination: male QSFP and male SFP+ terminations
• Jacket colour: black

How to use

Install the cable by aligning and inserting the QSFP plug into the corresponding QSFP port and connect the four SFP+ plugs to the target SFP+ ports. Ensure each connector latches securely to prevent intermittent connections. Verify port settings and link aggregation or breakout configuration on connected devices according to vendor documentation. Avoid sharp bends and maintain recommended bend radius for fibre assemblies during routing to preserve optical performance.

Recommendations

When deploying this QSFP-to-4xSFP+ cable, route it within cable management channels and maintain minimum bend radius to prevent signal loss. Confirm that connected ports support breakout operation and correct lane mapping. For environments with dense cabling, label both ends to simplify troubleshooting and future changes.
