InfiniBand/fibre optic cable BlueOptics 100G-DACP-QSFP4SFP5M-BL 5 m QSFP28 4xSFP28 Male/Male

The BlueOptics 100G-DACP-QSFP4SFP5M-BL is a 5 m InfiniBand/fibre optic cable with a QSFP28 connector on one end and four SFP28 connectors on the other. It is designed for high-speed data transmission between switches, servers and storage devices in data centre and enterprise networks. The cable's male-to-male configuration simplifies direct connections and reduces the need for additional transceivers when linking compatible ports.

Advantages

This fibre optic assembly supports 100 Gbps class connections through a QSFP28 interface and breaks out to four independent SFP28 links, enabling flexible port mapping and aggregation. The 5 m length balances reach and signal integrity for typical rack-to-rack or switch-to-server installations. The cable is manufactured to industry tolerances for optical performance to maintain low insertion loss and stable throughput under normal operating conditions.

Suitable for

• High-density data centre interconnects
• Server-to-switch or switch-to-switch direct connections
• InfiniBand and 100G Ethernet environments
• Aggregation and breakout applications where one QSFP28 needs to serve multiple SFP28 ports

Key specifications

• Cable type: multimode fibre optic assembly for QSFP28 to 4 × SFP28
• Connector configuration: male QSFP28 to 4 × male SFP28
• Nominal data rate: supports up to 100 Gbps aggregated bandwidth
• Length: 5 metres
• Colour: blue outer jacket
• Application: designed for InfiniBand and 100G Ethernet interconnects

How to use

Install the cable by inserting the QSFP28 end into a compatible QSFP28 port and the four SFP28 ends into the corresponding SFP28 ports on the target devices. Ensure connectors are clean and free of dust before insertion to avoid signal degradation. Confirm port settings and link aggregation or breakout configuration in the device firmware or operating system as required, then verify link status and throughput using network management tools.

Recommendations

Do not bend the cable sharply or exceed the recommended minimum bend radius. Store and handle the cable using protective caps on connectors when not in use. Use proper ESD precautions during installation and avoid routing the cable near high-power electrical lines to reduce interference and physical stress.
