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

The BlueOptics InfiniBand/fibre optic cable 5 m QSFP 4xSFP+ Black is a passive cable assembly designed to interconnect QSFP and SFP+ ports over a 5 metre length. It supports high-speed data transfer between network devices in data center and enterprise networking environments where QSFP-to-4xSFP+ breakout connectivity is required. The cable features a QSFP end and four SFP+ ends in a single, compact braided assembly finished in black, providing a tidy physical layout and reduced cable clutter.

Advantages

This 5 metre cable enables QSFP-to-4xSFP+ breakout without additional transceivers, simplifying rack cabling and reducing installation time. Its factory-terminated fibre optic connectors ensure consistent optical performance and reliable signal integrity. The compact multi-connector design allows flexible port mapping and efficient use of switch, router, and host adapter ports in dense networking setups. The black jacket and braided construction offer improved handling and resistance to wear during repeated moves or reconfigurations.

Suitable for

• Breaking out a QSFP port to four SFP+ ports in switches or routers
• High-speed InfiniBand and fibre channel interconnects in server racks
• Short-reach connections within data center cabinets and top-of-rack installations
• Testing and lab environments where modular port mapping is required

Key specifications

• Cable type: fibre optic breakout assembly (QSFP to 4×SFP+)
• Length: 5 metres
• Connector configuration: one QSFP end to four SFP+ ends
• Colour: black
• Use case: short-reach high-speed data interconnects

How to use

Insert the QSFP connector into a compatible QSFP port on a switch, router, or host adapter, and insert each SFP+ connector into the corresponding SFP+ ports on the target device. Ensure connectors are clean and ports are powered down or in maintenance mode as appropriate before insertion to avoid accidental link flaps. Route the cable to avoid sharp bends and secure it to cable management points to maintain minimum bend radius and reduce strain on connectors.

Recommendations

For reliable performance, use this cable for short-reach links within cabinets or between adjacent racks, keep connector end faces clean and capped when not in use, and follow equipment vendor guidance for QSFP-to-SFP+ breakout support and port configuration.
