Product information

Description

The Lightwin QSFP28 to QSFP28 DAC 100GbE Direct Attach Cable 3m is a passive twinax cable designed to provide a 100 Gigabit Ethernet connection between compatible QSFP28 ports. This 3-metre direct attach cable is intended for short-reach, high-bandwidth interconnects in data center environments and is listed as compatible with HP Aruba QSFP ports (model reference provided by manufacturer). The cable is black and fitted with QSFP28 male connectors on both ends for direct server-to-switch or switch-to-switch links.

Advantages

The cable delivers a fixed 100GbE physical connection using a passive QSFP28 twinax construction, providing a simple, low-latency option for short distances without requiring transceivers or additional optical components. At 3 metres length it balances reach and signal integrity for top-of-rack and adjacent-rack connections, while the QSFP28 connectors ensure compatibility with ports that accept QSFP28 direct attach modules.

Suitable for

  • Top-of-rack server to switch connections in data centers
  • Switch-to-switch short-reach uplinks within the same rack or adjacent racks
  • High-bandwidth aggregation links where 100GbE is required and fibre transceivers are not needed

When it may not be suitable

This passive DAC cable is designed for short-reach connections; it is not suitable for long-distance links or runs that exceed the specified 3 m length. It also requires devices with QSFP28 ports that accept passive direct-attach twinax cables; it will not function with devices that only support active optical modules or different connector form factors without appropriate adapters.

Key specifications

  • Cable type: Passive DAC (twinax)
  • Data rate: 100 Gbit/s
  • Connector type: QSFP28 male to QSFP28 male
  • Cable length: 3 m
  • Colour: Black

How to use

Ensure both network devices have QSFP28 ports that support passive DAC connections. Power down or follow hot-plug guidelines for your equipment, align the QSFP28 connectors and insert the cable ends firmly into the ports until the connector latch engages. Verify link status and speed in the device management interface. For removal, release the connector latch before gently pulling the cable out. Follow your equipment vendor’s guidance on hot-plugging and link negotiation.

What to consider before purchase

  • Confirm that both endpoints have QSFP28 ports and accept passive DAC cables
  • Verify that a 3 m cable length is appropriate for your rack layout and cable routing
  • Check compatibility notes for HP Aruba ports or your specific switch model if required

Usage recommendations

Use the Lightwin 3 m QSFP28 DAC for short, high-bandwidth links in racks or between adjacent racks. Avoid tight bends and mechanical strain on the twinax cable, maintain service loops as recommended by your hardware vendor, and confirm link settings after installation to ensure 100GbE operation.
