InfiniBand/fibre optic cable BlueOptics QSFP-4SFP10G-CU3M-HU 3 m 4xSFP+ Black

The BlueOptics QSFP-4SFP10G-CU3M-HU is a 3 m InfiniBand/fibre optic cable with a QSFP connector on one end and four SFP+ connectors on the other. Designed for high-density networking and server-to-switch interconnects, this cable supports aggregation of four 10 Gbps SFP+ links over a single QSFP port, enabling consolidated high-speed data transfer in data centers and enterprise environments. The cable uses a male-to-male connector configuration for direct, tool-free installation between compatible devices.

Advantages

This cable provides a compact, high-throughput link option by combining four SFP+ channels into one QSFP interface, reducing cable clutter and simplifying cabling in racks and switches. The 3 m length balances reach and signal integrity for short-reach links within racks or between adjacent racks. The design is intended for reliable electrical and optical performance suitable for 10 Gbps channels and for use in InfiniBand and fibre optic networking setups.

Suitable for

• Connecting QSFP ports to multiple SFP+ ports for aggregation or breakout applications
• High-density server and switch interconnects in data centers
• Short-reach links within server racks or between adjacent racks
• InfiniBand or fibre optic network environments requiring 10 Gbps channel links

Key specifications

• Length: 3 meters
• Connector configuration: 1 × QSFP (male) to 4 × SFP+ (male)
• Channel support: 4 × 10 Gbps SFP+ lanes over a single QSFP port
• Application: InfiniBand and fibre optic networking for short-reach aggregation
• Color: Black with blue product designation

How to use

Ensure both QSFP and SFP+ ports on the connected devices support breakout or passive aggregation and are powered down or hot-pluggable per device guidelines. Align the QSFP connector with the QSFP port and insert until it seats securely; then insert each SFP+ connector into the respective SFP+ ports. Verify link status and port configuration on the connected devices and configure link aggregation or lane mapping in the switch or host settings if required. Avoid excessive bending of the cable and maintain appropriate rack management to prevent strain on connectors.

Recommendations

Use the cable for short-reach, high-density interconnects inside racks or between adjacent racks. Follow equipment vendor guidelines for supported breakout modes and port settings. Store and route the cable to avoid tight bends and mechanical stress; verify compatibility with the host and switch firmware for optimal link negotiation.
