## Long description

The BlueOptics FN-CABLE-QSFP28-1-BL is a 1 m direct attach copper (DAC) cable with QSFP28 connectors on both ends, engineered for high-speed data transmission in dense network environments. Designed to meet InfiniBand interoperability requirements, this black cable provides a short-reach, low-latency link ideal for connections between switches, servers and storage in racks and data center topologies.
Advantages
This DAC cable offers a compact and passive solution for short-distance links, delivering reliable signal integrity and reduced latency compared with optical transceivers at the same port speeds. The QSFP28-to-QSFP28 termination supports 100 Gbit/s aggregated traffic (or compatible lane configurations), while the fixed 1 m length helps maintain predictable electrical performance and easy cable management. Its black outer jacket provides a consistent, professional appearance in structured cabling installations.
Suitable for
 High-density switch-to-switch or switch-to-server connections in data centers
 Server uplinks and top-of-rack (ToR) fabrics requiring QSFP28 interfaces
 InfiniBand fabrics and HPC cluster interconnects requiring short-reach links
 Connections between storage arrays and host adapters within the same rack
Key specifications
 Cable type: Direct Attach Copper (DAC)
 Cable length: 1 m
 Connectors: QSFP28 on both ends
 Typical application: Short-reach, high-speed interconnects (100 Gbit/s class)
 Weight: 0.15 kg
 Colour: Black
How to use
Install the BlueOptics QSFP28 DAC cable by aligning each QSFP28 connector with the corresponding port on your network equipment and press until the connector latches. Ensure equipment ports are powered down or that hot-plugging is supported by your devices if you connect while powered. Verify link negotiation and speed settings in the host or switch management interface after insertion. Avoid sharp bends and maintain manufacturer-recommended minimum bend radius to preserve signal integrity.
Usage recommendations
Use this 1 m DAC cable for short-distance interconnects inside racks or between adjacent racks to minimize latency and power consumption. Confirm QSFP28 port compatibility and supported link speeds on both devices before deployment, and route the cable to prevent mechanical strain or interference from power cords and moving parts.
