InfiniBand/optické vlákno priamy prepojovací kábel BlueOptics EX-QSFP-40GE-DAC-1M 1m QSFP konektor samec/konektor samec

The BlueOptics EX-QSFP-40GE-DAC-1M is a 1 metre InfiniBand/fibre optic direct-attach cable with QSFP male connectors on both ends. Designed for short-reach, high-throughput interconnects, this cable supports 40 Gigabit-class links and is intended for use in dense networking environments such as data centres and server racks. The blue jacket provides quick visual identification while the compact direct-attach form factor minimises signal loss and latency compared with longer active optical assemblies.

Advantages

This 1m QSFP-to-QSFP cable offers low latency and high signal integrity suitable for 40 Gigabit connections. Its passive direct-attach design reduces power consumption and complexity by eliminating the need for separate transceivers. The compact, industry-standard QSFP connector ensures broad compatibility with equipment that accepts QSFP interfaces. The robust outer sheath and factory-terminated connectors deliver consistent electrical performance and physical durability for frequent handling and dense installations.

Key specifications

How to use

Install the cable by inserting each QSFP connector firmly into the corresponding QSFP port on network devices, ensuring the latch engages. Use the 1 metre length to route between adjacent devices or within the same rack to minimise slack and avoid sharp bends. Verify link status on connected devices after insertion to confirm proper electrical connection. For removal, unlock the connector latch and pull straight to avoid damaging the port or cable.

Recommendations

Avoid tight bends and excessive pulling forces; maintain the manufacturer’s minimum bend radius. Use this passive 1m QSFP cable for short, direct connections — for longer distances or active equalisation needs choose an appropriate active optical or transceiver-based solution. Keep the connectors clean and protected when not in use to maintain signal quality.
