## Summary description

The BlueOptics QSFP28-DAC-2M-PS-BL is a 2-meter InfiniBand/fibre optic cable featuring QSFP28 connectors on both ends. Designed for high-speed data transmission, it ensures reliable connectivity in data centers and networking environments. The male/male configuration allows for easy connection between devices, making it ideal for high-performance computing applications.

## Long 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.
