## Summary description

The BlueOptics 100GB-C03-QSFP28-BL is a 3 m InfiniBand/fibre optic cable featuring QSFP28 to QSFP DAC connectors. It is designed for high-speed data transmission in data centers and networking environments. The male/male connectors ensure a secure connection, making it ideal for connecting switches and servers.

## Long description

The BlueOptics 100GB-C03-QSFP28-BL is a 3 m direct attach cable (DAC) with QSFP28 to QSFP28 connectors designed for high-speed InfiniBand and Ethernet/Fibre Channel applications. This passive twinax copper assembly supports 100G data rates over short rack-to-rack or intra-rack distances and provides a male-to-male connection suitable for linking switches, routers, storage systems and servers that accept QSFP28 DAC modules.
Advantages
The cable offers a straightforward, low-power physical connection without active transceivers, resulting in low latency and reduced power consumption. Constructed according to MSA-compliant QSFP28 specifications and using industry-standard components, it delivers reliable transmission for short-distance 100G links while maintaining cost efficiency compared with active optical modules. The fixed 3 m length simplifies deployment in racks and adjacent rack rows.
Suitable for
 High-density rack interconnects between switches and servers
 Short-distance data center links (intra-rack and adjacent racks)
 100G Ethernet, FCoE and InfiniBand connections supported by QSFP28 ports
 Storage arrays and high-performance computing clusters requiring 100G links
Key specifications
 Connector type: QSFP28 to QSFP28 (male/male)
 Length: 3 meters
 Cable type: Passive twinax copper (DAC)
 Data rate: up to 100 Gbit/s
 Wire gauge: 26 AWG twinax conductors
 Compliance: MSA-compliant QSFP28 electrical interface
How to use
Install the BlueOptics 3 m QSFP28 DAC by inserting each QSFP28 plug into corresponding QSFP28 ports on your network devices until the latch engages. Ensure both devices support passive QSFP28 DAC connections and that firmware or hardware compatibility is satisfied. Route the cable to avoid sharp bends and mechanical stress, and verify link status on connected devices after powering them on. For best results, use in short-range topologies such as within a rack or between adjacent racks.
Usage recommendations
Use this passive 100G DAC in environments where short, high-bandwidth links are required and where connected hardware explicitly supports passive QSFP28 direct-attach cables. Avoid extended outdoor or long-reach applications; for distances beyond a few meters, consider active optical transceivers or fiber optics.
