Product information

Description

The BlueOptics QFX-QSFP28-DAC-3M-BL is a 3-meter direct attach cable with QSFP28 connectors on both ends, designed for short-reach high-speed links in data centers and rack environments. It supports up to 100G transmission and is suitable for InfiniBand and Ethernet applications where a passive twinax copper or equivalent direct attach solution is required. The male-to-male QSFP28 configuration provides physical compatibility with switches, routers and storage systems that accept QSFP28 DAC modules.

Advantages

This 3m QSFP28 direct attach cable offers a low-latency, low-power connection for short-distance links and rack-to-rack interconnects. Its passive design reduces complexity and failure points compared with active optical modules, while the rugged QSFP28 connectors and quality components ensure stable performance and long service life. The cable is suitable for environments where predictable latency and energy efficiency are priorities.

Suitable for

  • 100G Ethernet links between switches in the same rack or adjacent racks
  • InfiniBand high-performance computing interconnects over short distances
  • Direct attach connections to storage arrays and routers that support QSFP28 DACs

Key specifications

  • Connector type: QSFP28 to QSFP28, male/male
  • Length: 3 meters
  • Supported data rate: up to 100 Gbps
  • Cable type: direct attach (twinax / passive DAC) suitable for short-reach electrical transmission
  • Wire gauge: 26 AWG (as typical for this cable family)
  • Compliance: MSA-compliant QSFP28 form factor and electrical interface

How to use

Install the BlueOptics QSFP28 DAC by aligning each QSFP28 connector with the port on the corresponding switch, router or storage device and inserting until the latch engages. Ensure both devices support passive QSFP28 direct attach cables and the targeted protocol (Ethernet, FCoE or InfiniBand) at 100G. Route the cable to avoid sharp bends, excessive tension and sources of electromagnetic interference. If the host requires specific cable recognition, verify compatibility with the device vendor and test the link after installation.

Usage recommendations

Use this 3m passive QSFP28 DAC for short-distance, high-bandwidth links inside racks and between adjacent racks. Confirm device support for passive DACs and follow vendor guidance for QSFP28 port configuration and transceiver settings to achieve optimal performance.
