Product information

Description

BlueLAN UACC-DAC-QSFP28-3M is a 3 meter passive direct attach copper cable with QSFP28 connectors on both ends. It supports 100GBASE-CR4 and InfiniBand EDR link protocols and is constructed with 26AWG conductors for reliable short-range, high-bandwidth connections. Designed for use in data centers and high-performance computing environments, this cable provides a low-latency, power-efficient physical interconnect between switches, routers and servers.

Advantages

The cable offers native support for 100GBASE-CR4 and InfiniBand EDR, enabling high-throughput 100 Gbps links without requiring optical transceivers. Passive copper construction reduces power consumption compared with active or optical solutions for short distances. QSFP28-to-QSFP28 connectivity ensures compatibility with equipment ports that accept QSFP28 modules, while the 3 m length balances reach and signal integrity for rack- and row-level interconnects. Use of 26AWG conductors provides mechanical flexibility and adequate current-carrying capacity for short-reach data links.

Suitable for

  • Interconnecting rack-mounted switches and aggregation devices
  • Server-to-switch high-speed uplinks in data centers
  • Short-reach links in high-performance computing (HPC) clusters using InfiniBand EDR
  • Temporary or permanent 100 Gbps point-to-point connections inside equipment cabinets

Key specifications

  • Connector type: QSFP28 to QSFP28
  • Cable length: 3 meters
  • Supported protocols: 100GBASE-CR4, InfiniBand EDR
  • Conductor size: 26 AWG
  • Cable type: Passive direct attach copper (DAC)
  • Typical application: Short-range, high-bandwidth interconnects in data center environments

How to use

Install the cable by inserting each QSFP28 connector into matching QSFP28 ports on your network devices until the latch engages; ensure ports are powered down or traffic is disabled according to your maintenance procedures if required. Verify link status and negotiated speed through device management interfaces after connection. The cable is intended for direct attachment and does not require separate transceivers or additional configuration beyond standard port settings on compatible equipment.

Usage recommendations

Route the cable to avoid sharp bends and mechanical stress; maintain the manufacturer’s minimum bend radius and avoid kinks. Use the 3 m length for intra-rack or short inter-rack connections where passive DACs meet performance and power objectives. Confirm device compatibility with QSFP28 passive copper cables and check port firmware or vendor compatibility lists if operating near maximum supported distances.
