Product information

Description

Lightwin QSFP28 to QSFP28 DAC 100 Gbit Direct Attach Cable LWO-DAC-QSFP28-3M is a passive twinax copper cable with a 3 m length, engineered for short-reach, high-speed interconnects. It connects QSFP28 ports on switches, routers and network adapters to deliver 100 Gbit/s point-to-point links with low latency and predictable electrical performance. The cable is intended for use in data center top-of-rack and server-to-switch scenarios where a compact, cost-effective direct-attach solution is required.

Advantages

The Lightwin 3 m QSFP28 DAC provides a straightforward physical connection that requires no additional transceivers or optical modules, reducing component count and power consumption. Its passive twinax construction offers consistent signal integrity over short distances, and the QSFP28-to-QSFP28 form factor maintains full 100 Gbit/s bandwidth for compatible ports. The black jacket and compact connector housings support dense cabling runs while keeping rack layouts tidy.

Suitable for

  • Short-reach 100 Gbit/s links between switches in the same rack or adjacent racks
  • Server-to-switch connections where QSFP28 ports are available on both ends
  • Data center uplinks and spine-leaf topologies requiring low-latency copper links

When it may not be suitable

This passive DAC is designed for short distances and will not replace optical transceivers for long-reach connections; it is limited by electrical attenuation and channel requirements. It also requires both devices to have QSFP28 ports and to support passive DAC compatibility; some network equipment may restrict third-party or passive cable use.

Key specifications

  • Cable type: Direct Attach Copper (DAC), passive twinax
  • Data rate: 100 Gbit/s
  • Connector type: QSFP28 to QSFP28 (male to male)
  • Cable length: 3 m
  • Colour: Black
  • Typical application: Short-reach, high-speed interconnects in data centers

How to use

Ensure both devices have powered QSFP28 ports and that their firmware and configuration permit direct-attach passive cables. Align the QSFP28 connectors with the port guides and insert until the retention latch engages; follow the host equipment procedure for link activation. For removal, depress the connector latch and pull straight out. Verify link status through the network device management interface and monitor for expected 100 Gbit/s operation.

What to consider before purchase

  • Confirm both endpoints have QSFP28 ports and support passive DACs
  • Verify that a 3 m passive twinax cable meets your reach and rack layout requirements
  • Check equipment vendor policies for third-party passive cable compatibility

Usage recommendations

Use the Lightwin QSFP28 to QSFP28 3 m DAC for short, fixed-length interconnects inside racks or between adjacent racks, avoid tight bends near the connectors, and keep the cable secured to reduce mechanical stress. Verify link negotiation and monitor for expected throughput after installation.
