BlueOptics AT-QSFP2CU-BL Καλώδιο InfiniBand/οπτικών ινών 2 m QSFP Μαύρο

The BlueOptics AT-QSFP2CU-BL is a 2 m QSFP direct attach cable (DAC) designed for short-range, high-speed connections in data centers and network racks. This passive twinax copper cable provides QSFP-to-QSFP male connectors and supports protocols including 40G Ethernet and InfiniBand. It is intended for linking switches, routers, storage systems and other hardware platforms that accept QSFP passive DACs and comply with MSA specifications.

Advantages

The cable is a passive 40G twinax solution with low power consumption and low latency suitable for short-distance links up to 2 meters. Constructed to industry MSA standards, it offers electrical and mechanical interoperability with compatible hardware. Components and assembly follow established quality practices to provide consistent performance for rack-to-rack and in-rack connections.

Suitable for

• High-density rack interconnects and adjacent rack links
• 40G Ethernet and InfiniBand connections between QSFP ports
• Switch-to-switch, switch-to-router and switch-to-storage links within 2 m
• Data center top-of-rack and spine-leaf short-reach connections

Key specifications

• Length: 2 meters
• Connector type: QSFP male to QSFP male
• Cable type: Passive twinax copper (DAC)
• Supported data rate: up to 40 Gbps per cable (protocol-dependent)
• Wire gauge: 30 AWG
• Compliance: MSA-compatible QSFP DAC electrical and mechanical interface

How to use

Install the BlueOptics AT-QSFP2CU-BL by inserting each QSFP connector into the corresponding QSFP port on the devices to be linked. Ensure both devices support passive QSFP DACs and the selected protocol (for example 40GBase-CR4, InfiniBand or FCoE). Avoid bending the cable beyond recommended limits and confirm firm seating of connectors to maintain reliable electrical contact.

Recommendations

Use this 2 m passive QSFP twinax cable for short, high-performance links within racks and between adjacent racks. Verify compatibility with the hardware vendor’s documentation for passive QSFP DAC support and follow standard data-center handling: route the cable to minimize stress, avoid tight bends, and keep connections dust-free.
