## Summary description

The BlueOptics DAC-QSFP28-100G-3M-BL is a 3-meter DAC cable designed for high-speed data transmission. It features QSFP28 connectors on both ends, ensuring reliable connectivity for 100G applications. Ideal for data centers and high-performance computing environments.

## Long description

The BlueOptics DAC-QSFP28-100G-3M-BL is a 3-meter direct attach copper (DAC) cable with QSFP28 connectors on both ends, designed for 100G high-speed data links. It provides a fixed, low-latency, and power-efficient connection option for short-reach interconnects in racks and between adjacent network equipment. The cable is intended for environments where reliable 100 Gigabit Ethernet connectivity and minimal signal loss are required.
Advantages
This DAC cable delivers consistent 100G throughput with low insertion loss and negligible latency compared to optical transceivers. The QSFP28-to-QSFP28 termination ensures plug-and-play compatibility with compatible 100G ports, reducing setup time. As a copper direct attach solution, it offers lower power consumption and total cost of ownership for short-range connections compared with active optical modules. Its fixed length simplifies cable management in dense rack deployments.
Suitable for
 Server-to-switch and switch-to-switch connections within the same rack or adjacent racks
 Top-of-rack (ToR) and spine-leaf architectures in data centers
 High-performance computing clusters requiring 100G links
 Test labs and network provisioning environments with short-reach requirements
Key specifications
 Connector type: QSFP28 male to QSFP28 male
 Nominal data rate: 100 Gbps
 Cable length: 3 meters
 Physical medium: direct attach copper (DAC)
 Typical use: short-reach interconnects within racks or between adjacent racks
 Latency: minimal, passive copper connection
How to use
Power down or follow hot-swap guidelines of your equipment and insert each QSFP28 connector into the corresponding 100G port until it latches. Ensure ports are compatible with passive DAC cables and verify link status through your switch or server management interface. For hot-pluggable systems, confirm vendor support for DAC modules before insertion to avoid port or system errors. Route the cable to avoid sharp bends and mechanical strain on connectors.
Usage recommendations
Use this DAC cable for short-distance, high-bandwidth interconnects where electrical connectivity is supported and heat dissipation is within equipment specifications. Avoid bending the cable beyond manufacturer-recommended bend radius and keep it clear of power supplies or heat sources. Verify compatibility with your network devices and firmware to ensure full 100G operation.
