Product information

Description

The CBO Direct Attach Copper (DAC) Cable QSFP28-DAC-2M is a 2‑meter passive copper cable designed for short-range 100GbE connections between devices with QSFP28 ports, compatible with Chelsio equipment. It delivers a fixed, low-latency link suitable for top-of-rack switches, servers and network interface cards where reliable, high-throughput connectivity is required. The plug-and-play form factor eliminates the need for transceivers and simplifies installation in dense rack environments.

Advantages

The QSFP28-DAC-2M provides low latency and consistent signal quality for short-distance 100GbE links. Its passive copper construction offers power-efficient operation compared with active optical solutions for similar short ranges. The cable’s QSFP28 connectors ensure straightforward interoperability with compliant QSFP28 ports and reduce inventory complexity by avoiding separate transceivers. Its 2 m length is optimized for connections within racks and between adjacent racks in data center deployments.

Suitable for

  • Top-of-rack switch to server 100GbE links
  • Inter-switch connections within the same rack or adjacent racks
  • Direct connections to QSFP28-capable NICs and network adapters
  • High-performance computing (HPC) clusters requiring low-latency links

Key specifications

  • Connector type: QSFP28 to QSFP28
  • Length: 2 meters
  • Media: Passive copper twinaxial
  • Bandwidth: 100 Gbps (aggregate)
  • Typical use case: Short-range, rack-level 100GbE connections
  • Compatibility note: Designed for interoperability with Chelsio QSFP28 ports

How to use

Insert each QSFP28 connector into the corresponding QSFP28 port on the devices to be connected until the connector latches. Ensure ports are powered down or follow your equipment vendor’s hot-plug guidance if available; most systems support hot-insertion of DAC assemblies. Verify link status and interface configuration in the device management interface; standard Ethernet configuration and driver support apply. For best performance, maintain a clean routing path inside the rack and avoid excessive bending or strain on the cable assemblies.

Usage recommendations

Use this 2 m QSFP28 DAC for short, direct 100GbE links inside racks or between adjacent racks. Avoid extended runs beyond the specified length and minimize tight bends; store and route the cable to prevent damage to the connector latches or cable shielding. Confirm firmware and driver compatibility on Chelsio or other vendor equipment to ensure proper link negotiation.
