Product information

Description

The BlueOptics CAB-Q-Q-100G-3M-BL is a 3-meter passive Direct Attach Cable (DAC) with QSFP28 connectors on both ends. Designed for short-distance, high-speed data transmission, this 100GBase-CR4 twinax copper cable uses 26 AWG conductors and follows MSA-compliant QSFP28 specifications to ensure electrical and mechanical interoperability with compatible network equipment. The cable is intended for rack-to-rack and intra-rack connections in data centers and high-performance computing environments where low latency and reliable 100 Gbps links are required.

Advantages

This QSFP28 DAC offers low latency and low power consumption typical of passive twinax copper solutions. MSA compliance and QSFP28 connectors provide broad compatibility with hardware that supports 100GBase-CR4 over passive DACs. The 3 m length is suitable for connecting devices within or between adjacent racks while minimizing signal loss. The cable is produced to use quality components and meets common industry requirements for short-reach copper interconnects.

Suitable for

  • Rack-to-rack connections in data centers
  • Intra-rack links between switches, routers and storage systems
  • High-performance computing cluster interconnects
  • Environments requiring low-latency 100 Gbps links

Key specifications

  • Connector type: QSFP28 to QSFP28
  • Nominal data rate: up to 100 Gbps (100GBase-CR4)
  • Length: 3 meters
  • Cable type: passive twinax copper (DAC)
  • Conductor gauge: 26 AWG
  • MSA-compliant QSFP28 interface
  • Low power passive design

How to use

Install the BlueOptics CAB-Q-Q-100G-3M-BL by inserting each QSFP28 connector into the corresponding QSFP28 port on your network devices until the connector latches. Ensure both devices support passive DACs and the 100GBase-CR4 electrical interface. Route the cable to avoid sharp bends and mechanical strain; maintain recommended bend radius for twinax cable and secure the cable to rack structures where appropriate. When removing the cable, release the latch per the device instructions before pulling the connector straight out to avoid damage.

Usage recommendations

Verify device compatibility with QSFP28 passive DACs and the 100GBase-CR4 protocol before deployment. Use the 3 m length for short-reach connections inside or between adjacent racks; for longer distances consider active DACs or optical transceivers. Regularly inspect connectors and cable jacket for damage and ensure cable routing prevents excessive bending or compression to preserve signal integrity.
