Product information

Description

Lightwin DAC QSFP28 to QSFP28 0.5 m Black is a direct attach copper (DAC) cable with QSFP28 connectors on both ends, designed for short-reach 100 Gbit/s links. The 0.5 m length and robust black jacket make it suitable for connections inside racks and between adjacent network devices where low-latency, high-bandwidth links are required.

Advantages

This DAC cable provides a cost-effective, low-latency physical connection for 100 Gbit/s ports without the need for optical transceivers. With QSFP28-to-QSFP28 termination and a short 0.5 m length, it reduces power consumption compared with active optical options and simplifies installation in dense rack environments.

Suitable for

  • Short-reach interconnects between switches and routers within the same rack
  • Direct connections between network interface cards (NICs) and switches
  • Server-to-switch links in data centre and high-performance computing racks

When it may not be suitable

This cable is intended for short distances (0.5 m) and is not suitable for long-distance or campus links. It is a passive copper direct attach cable and therefore not appropriate where optical fibre connections or active optical cables are required for longer reach, lower electromagnetic susceptibility, or fibre-based infrastructure.

Key specifications

  • Data rate: 100 Gbit/s
  • Connector types: QSFP28 to QSFP28
  • Cable type: Direct Attach Copper (DAC)
  • Length: 0.5 m
  • Mode: multi-mode compatible for short-reach applications
  • Colour: Black

How to use

Install by plugging each QSFP28 connector into the corresponding QSFP28 port on your switches, NICs, or servers, ensuring the latch engages. No additional configuration is required at the physical layer; verify link status in device management after connection. Route the cable within the rack to avoid sharp bends and mechanical strain on connectors.

What to consider before purchase

  • Confirm both devices have QSFP28 ports that support direct attach copper connections
  • Ensure the 0.5 m length fits the intended rack layout and port locations
  • Check device compatibility and supported link speeds in vendor documentation

Usage recommendations

Use this Lightwin QSFP28 DAC for short, high-bandwidth links inside racks; avoid excessive bending and secure the cable to prevent connector strain. For longer distances or fibre-only infrastructures, consider optical transceivers or active optical cables instead.
