Product information

Description

The BlueOptics QSFP28-DAC-2M-PS-BL is a 2 meter direct attach cable (DAC) with QSFP28 connectors on both ends, designed for short-reach high-speed links in racks and between adjacent racks. This passive twinax copper cable supports 100GBase-CR4 electrical signalling and InfiniBand/Fibre Channel/Ethernet protocols at up to 100 Gbit/s over a 2 m distance. The cable follows MSA-compatible QSFP28 mechanical and electrical specifications and is intended for use with hardware platforms that support QSFP28 passive DACs.

Advantages

The QSFP28-DAC-2M-PS-BL provides low latency and low power consumption typical of passive twinax DACs, while offering a cost-effective connectivity option for data-centre top-of-rack and adjacent-rack links. Its QSFP28 male-to-male configuration ensures straightforward plug-and-play connections between switches, routers, storage systems and servers that accept passive QSFP28 modules. Manufactured with industry-grade components and MSA compliance, the cable is built for consistent interoperability and long operational life in professional networking environments.

Suitable for

  • 100G direct attach links between switches, routers and storage in rack and adjacent-rack setups
  • InfiniBand and Ethernet interconnects requiring QSFP28 passive twinax cabling
  • High-performance computing clusters and server-to-switch connections over short distances
  • Environments where low latency, low power and cost-effective cabling are required

Key specifications

  • Length: 2 meters
  • Connector type: QSFP28 male to QSFP28 male
  • Media type: Passive twinax copper (DAC)
  • Supported data rates: up to 100 Gbit/s (100GBase-CR4)
  • Wire gauge: 30 AWG twinax conductors
  • Protocol support: Ethernet, FCoE, Fibre Channel, InfiniBand (as supported by host hardware)
  • Compliance: MSA-compatible QSFP28 mechanical/electrical interface

How to use

Ensure both devices support passive QSFP28 DACs and the intended protocol (e.g., 100GBase-CR4). Power down or follow hot-swap procedures per your equipment vendor when inserting or removing QSFP28 modules if required. Align each QSFP28 plug with the corresponding port and insert until the module seats and latches. Verify link status and negotiated speed on connected devices and confirm that firmware or switch settings do not restrict use of passive DACs. For best performance, avoid tight bends and undue strain on the cable and maintain proper rack routing to prevent interference with airflow.

Usage recommendations

Use this 2 m passive QSFP28 twinax cable for short-distance 100G links inside racks and between adjacent racks. Verify compatibility with your hardware vendor's supported cable and firmware lists before deployment. Route the cable with gentle bends (observe manufacturer bend radius) and protect connectors from contamination when not in use.
