Product information

Description

The BlueOptics QSFP28-DAC-5M-VA-BL is a 5-metre direct attach copper (DAC) cable with QSFP28 connectors on both ends, designed for short-reach high-speed links in data centers and networking racks. It provides a passive twinax copper connection suitable for 100GBase-CR4 applications and is intended for connecting switches, routers and storage systems across adjacent racks or within the same rack with minimal signal loss and low latency.

Advantages

This QSFP28 DAC cable offers a cost-effective and energy-efficient way to implement short-distance 100 Gbps links. As a passive twinax copper solution it consumes very low power, has low latency and a simple, robust design that reduces failure points compared with active transceivers. The cable is MSA-compliant and manufactured using industry-grade components to ensure consistent electrical performance and long operating life for typical data center use.

Suitable for

  • Short-reach 100 Gbps connections between switches and routers
  • Inter-rack connections in data center racks and server cabinets
  • Direct links between storage systems and network equipment
  • Environments requiring low-latency, low-power copper links

Key specifications

  • Connector type: QSFP28 to QSFP28 (male/male)
  • Cable length: 5 metres
  • Media: passive twinax copper (DAC)
  • Supported data rate: up to 100 Gbps (100GBase-CR4 compatible)
  • Wire gauge: 26 AWG
  • Typical applications: Ethernet, Fibre Channel, FCoE, InfiniBand (up to 100G where supported)

How to use

Install the BlueOptics QSFP28-DAC-5M-VA-BL by inserting each QSFP28 connector into the corresponding QSFP28 ports on your networking devices while the equipment is powered down or per the device manufacturer’s hot-plug guidance. Ensure ports support passive DAC cables and the intended 100GBase-CR4 or equivalent transmission protocol. After connection, verify link status and negotiated speed through your switch or host interface management. Route the cable to avoid sharp bends and mechanical strain, and secure it within the rack to prevent stress on connectors.

Usage recommendations

Use this DAC cable for short-distance fixed links inside racks or between adjacent racks where a passive copper solution is supported. Confirm device compatibility with QSFP28 passive twinax cables and the required 100G protocol prior to deployment. Avoid tight cable bends and exposure to excessive heat or fluids; store and handle the cable following common data center cabling best practices.
