InfiniBand-/kuituvalokaapeli BlueOptics JNP-QSFP-DAC-2M 2 m uros/uros

The BlueOptics JNP-QSFP-DAC-2M is a 2 m InfiniBand/fibre optic cable with Male-to-Male QSFP connectors designed for high-speed data transmission in data centres and professional networking environments. The cable supports direct attach connections between compatible QSFP ports, offering a compact, low-latency option for short-reach links where predictable performance and physical reliability are required.

Advantages

This QSFP direct-attach cable provides a fixed, 2-metre channel with low insertion loss and minimal latency compared with longer multimode patching solutions. The male-to-male QSFP interface ensures straightforward plug-and-play installation with compatible switches, routers and host adapters. The construction is optimised for secure mechanical mating and stable signal integrity in dense rack installations.

Suitable for

• Short-reach uplinks between switches and leaf/spine architectures in data centres
• Direct connections between servers and network adapters supporting QSFP interfaces
• High-performance computing clusters using InfiniBand or QSFP-based interconnects
• Environments requiring predictable latency and stable physical link behaviour

Key specifications

• Cable length: 2 metres
• Connector type: QSFP male to QSFP male
• Application: InfiniBand and fibre optic high-speed interconnects
• Designed for short-reach, direct-attach connections
• Mechanical design for dense rack and data centre use

How to use

Verify that both network devices support QSFP direct-attach connections and are powered off or in a recommended maintenance state before insertion if required by the device vendor. Align the QSFP male connectors with the module sockets and insert firmly until the connector latches. After installation, check link status on both devices and monitor for any link errors. For removal, press the release mechanism and extract the connector evenly to avoid stress on ports and cables.

Recommendations

Route the cable to avoid sharp bends and secure it in the rack to prevent strain on the QSFP connectors. Maintain the specified 2 m length for predictable signal characteristics; avoid adding adapters or extensions that can increase insertion loss. Follow your equipment vendor's guidelines for hot-plugging and ESD precautions when handling QSFP direct-attach cables.
