Product information

Description

The BlueOptics QSFP28-DAC-5M-QL InfiniBand fibre optic cable 5m Male/Male is a direct-attach cable designed for short-reach, high-speed connections in data centres and networking racks. With QSFP28 connectors on both ends and a five-metre length, this cable supports tight integration between switches, servers and storage systems where low latency and reliable throughput are required.

Advantages

This male-to-male QSFP28 direct-attach cable offers a compact, cost-efficient solution for high-bandwidth links. It delivers consistent signal integrity over the full five-metre span, minimising insertion loss and reducing the need for additional transceivers. The cable's construction is tailored for dense rack environments and provides stable electrical performance for InfiniBand and other QSFP28-compatible interfaces.

Suitable for

  • Interconnecting switches, servers and storage within the same rack or adjacent racks
  • High-performance computing (HPC) clusters using InfiniBand fabrics
  • Top-of-rack (ToR) and aggregation layer connections
  • Short-reach uplinks where QSFP28 form factor is required

Key specifications

  • Connector type: QSFP28 male to QSFP28 male
  • Length: 5 metres
  • Supported protocol: InfiniBand; compatible with QSFP28 electrical interfaces
  • Bandwidth capability: designed for 100 Gbps-class QSFP28 links
  • Cable type: direct attach copper/active direct attach (as appropriate for QSFP28 DACs)
  • Application environment: data centre racks and telecom equipment enclosures

How to use

Ensure both devices to be connected support QSFP28 ports and that the port configuration matches the intended InfiniBand or Ethernet link settings. With equipment powered down or ports administratively disabled, insert each QSFP28 connector firmly into the corresponding port until the latch engages. Re-enable ports or power up equipment and verify link status via the host interfaces or management software. For troubleshooting, reseat connectors and confirm port compatibility and firmware settings on connected devices.

Usage recommendations

Install and route the cable to avoid sharp bends and excessive strain; maintain the minimum bend radius recommended by the equipment manufacturer. Use appropriate airflow and cable management practices in racks to preserve signal performance and simplify service access. When replacing or adding links, verify compatibility with host vendor QSFP28 specifications and update link settings as needed.
