BlueOptics 100G-DACP-QSFP3M-BL InfiniBand fibre optic cable 3 m QSFP28 Black

The BlueOptics 100G-DACP-QSFP3M-BL InfiniBand fibre optic cable is a 3 m QSFP28 passive direct attach copper-style cable presented in a flexible, black jacket. With male QSFP28 connectors on both ends, this cable is engineered for short-reach, high-bandwidth interconnects in data centers and high-performance networking environments. It supports 100G data rates and is intended to provide low latency and dependable signal integrity between switches, routers and servers.

Advantages

This 3 m InfiniBand cable offers a compact solution for connecting high-speed ports without transceivers, reducing overall power consumption and simplifying installation. The QSFP28 male connectors ensure a standardized interface for 100G-capable equipment, while the durable outer jacket and tight construction maintain consistent performance in rack and chassis environments. The passive design reduces complexity and is suitable where short-distance, high-throughput links are required.

Suitable for

• High-density switch-to-switch connections in data centers
• Server-to-switch links for storage and compute clusters
• Interconnects in high-performance computing (HPC) and InfiniBand networks
• Short-reach backbone cabling within racks and between adjacent racks

Key specifications

• Cable type: InfiniBand passive direct attach
• Connector type: QSFP28 male on both ends
• Supported data rate: 100 Gbit/s
• Length: 3 meters
• Color: Black
• Design: Short-reach, low-latency interconnect

How to use

Install the cable by aligning each QSFP28 male connector with the corresponding QSFP28 port on network equipment and insert until the connector is seated securely. Ensure equipment is powered down or supports hot-plugging per manufacturer guidance before connecting or disconnecting. Route the cable to avoid sharp bends and mechanical strain; maintain minimum bend radius as specified by the equipment vendor. Verify link status via switch or server port indicators and network management tools after installation.

Usage recommendations

For reliable operation, use this BlueOptics 3 m QSFP28 cable for short-distance connections within racks or between adjacent racks. Avoid exceeding recommended bend radii and protect connectors from dust by using dust caps when ports are not in use. Confirm compatibility with your 100G-capable QSFP28 ports and check device documentation for supported passive direct attach cables.
