## Long description

BlueOptics DAC cable CBO QSFP28-DAC-5M is a 5‑metre Direct Attach Copper (DAC) cable engineered for QSFP28 ports. It provides a fixed copper link for short-range, high-speed connections between switches, routers and servers that support QSFP28. The assembly eliminates the need for separate transceivers by combining the cable and plug-terminated connectors into a single, low-latency electrical interconnect suitable for data centre top-of-rack and rack-to-rack links.
Advantages
This QSFP28 DAC cable offers stable electrical performance with minimal insertion loss and predictable latency, making it suitable for high-throughput environments. The 5 m length balances reach and signal integrity for typical rack and adjacent-rack deployments while keeping power consumption and heat lower than active optical solutions. The plug-and-play form factor enables quick installation and replacement without additional configuration or transceiver modules.
Suitable for
 Short-range QSFP28 interconnects in data centre top-of-rack and end-of-row deployments
 High-bandwidth links between servers and switches or between aggregation devices
 Low-latency connections for trading, HPC, virtualization and storage fabrics
 Cost-effective cabling for environments where optical transceivers are not required
Key specifications
 Connector type: QSFP28-to-QSFP28 direct-attach copper
 Cable length: 5 metres
 Media: passive copper assembly for short-reach electrical links
 Data rates supported: compatible with 100Gbps QSFP28 electrical interfaces
 Latency: low, fixed electrical latency suitable for time-sensitive traffic
 Form factor: pre-terminated, plug-and-play design
How to use
Install the BlueOptics QSFP28-DAC-5M by inserting each QSFP28 connector into the corresponding QSFP28 port on your network devices until the latch engages. Ensure ports are powered down or follow hot-plug guidance from your equipment vendor if connecting live. The cable is ready to use without additional configuration; network devices will recognise the electrical link as a standard QSFP28 interface. For best results, avoid sharp bends and excessive strain on the cable and secure routing inside racks to prevent movement or connector stress.
Usage recommendations
Use this DAC cable for short-distance, high-bandwidth links where electrical interconnects are supported and preferred. Verify compatibility with your switch or server vendor's supported transceiver and cable lists to ensure firmware interoperability. Store and route the cable to avoid kinks, and replace the cable if connectors show physical wear or degraded link performance.
