## Long description

The BlueOptics 49Y7888 InfiniBand fibre optic cable 5 m QSFP 4xSFP+ Black is a 5-metre multimode fibre assembly that connects a QSFP port to four SFP+ ports. Designed for high-density network environments, this cable supports aggregated high-speed data links with low attenuation and controlled crosstalk, enabling dependable connections between switches, servers and storage systems in data centres and server rooms.
Advantages
This fibre optic cable combines a single QSFP male connector with four SFP+ male connectors to deliver aggregated bandwidth while reducing cabling complexity. The 5 m length balances reach and manageability in rack-mounted and top-of-rack deployments. Engineered for InfiniBand environments, the cable delivers low signal loss and consistent optical performance across all channels, and its ruggedised jacket in black provides mechanical protection and easy identification in cable trays.
Suitable for
Interconnecting QSFP-equipped switches to multiple SFP+ ports on servers or NICs
High-density rack or top-of-rack installations in data centres
Short-reach InfiniBand links for compute clusters and storage arrays
Consolidating multiple 10 Gb/s SFP+ links into a single QSFP port
Key specifications
Connector configuration: QSFP on one end, 4 × SFP+ on the other
Length: 5 metres
Fibre type: multimode (InfiniBand-compatible)

How to use
Install the QSFP end into a compatible QSFP port and insert each SFP+ connector into the corresponding SFP+ ports on the target devices. Ensure ports are powered down or follow live-insertion guidelines provided by your hardware vendor if supported. Route the cable to avoid tight bends; maintain the specified minimum bend radius to prevent increased attenuation. Verify link status indicators on connected devices to confirm successful negotiation and data transmission.
Usage recommendations
For optimal performance, use this cable for short-reach aggregated links within racks or between adjacent racks. Avoid exposure to excessive tensile stress and maintain proper cable management to reduce the risk of connector damage and signal degradation.
