Product information

Description

The BlueOptics QSFP28-100G-CU5M-BL InfiniBand/fibre optic cable is a 5 m direct-attach assembly with QSFP28 male connectors on both ends. Engineered for short-reach, high-bandwidth links, this passive twinax copper cable supports 100GBase-CR4 and is intended for use in data center and high-performance networking equipment that accept QSFP28 direct-attach cables. The cable uses 26 AWG conductors and follows MSA-compliant QSFP28 electrical and mechanical specifications, providing a straightforward physical connection for switches, routers and storage systems over a 5 meter distance.

Advantages

This passive QSFP28 twinax cable offers low latency and low power consumption compared with active optical modules, making it suitable for short-distance interconnects inside racks and between adjacent racks. Compliance with MSA QSFP28 standards and the use of high-quality components help ensure reliable interoperability with hardware platforms that support 100GBase-CR4. The fixed 5 m length simplifies cable management for rack-to-rack connections and reduces the need for external transceivers or additional power draw.

Suitable for

  • High-speed switch-to-switch links within or between adjacent racks
  • Server-to-switch and storage-to-switch connections in data centers
  • InfiniBand and Ethernet environments requiring 100 Gbit/s short-reach connectivity
  • Environments where low latency and minimal power consumption are required

Key specifications

  • Connector type: QSFP28 male to QSFP28 male
  • Length: 5 meters
  • Transmission: passive twinax copper, 100GBase-CR4 capable
  • Wire gauge: 26 AWG
  • Supported protocols: Ethernet (100G), FCoE, Fibre Channel, InfiniBand (up to 100 Gbit/s)
  • Form factor: direct attach cable (DAC) for short-reach links

How to use

Install the cable by inserting each QSFP28 connector into the corresponding QSFP28 port on your networking devices until the latch engages. Ensure both devices support passive QSFP28 direct-attach cables and the 100GBase-CR4 or respective protocol you intend to run. Avoid excessive bending or kinking of the cable and route it to minimize mechanical stress and airflow obstruction in the rack. Verify link status and speed on connected devices after installation and consult equipment logs if the connection does not establish.

Usage recommendations

Use this 5 m passive DAC for short-range connections inside racks or between adjacent racks where the host hardware explicitly supports passive QSFP28 direct-attach cables. Maintain recommended bend radius for twinax assemblies, keep the cable away from heat sources and ensure firmware or driver settings on connected equipment allow passive 100GBase-CR4 connections.
