BlueOptics JNP-100G-DAC-1M InfiniBand fibre optic cable QSFP28 1m Male/Male

The BlueOptics JNP-100G-DAC-1M InfiniBand fibre optic cable QSFP28 1m Male/Male is a 1-metre direct attach cable engineered for high-speed connections in data centres and enterprise networking racks. Featuring QSFP28-compatible male-to-male connectors, this cable supports 100Gb/s class InfiniBand links and is intended for short-reach, low-latency interconnects between switches, servers and storage nodes. The compact, single-metre length helps maintain clean cable runs while providing a reliable physical layer connection for high-throughput environments.

Advantages

This QSFP28 InfiniBand cable delivers predictable signal integrity and low insertion loss for short-distance, high-bandwidth links. Its male-to-male QSFP28 termination simplifies direct connections without requiring transceiver modules, reducing component count and potential points of failure. The fixed 1 m length minimises excess cabling in dense rack deployments and helps improve airflow and cable management. Materials and construction are selected to meet the mechanical and electrical requirements typical of professional data-centre infrastructure.

Key specifications

How to use

Insert the QSFP28 male connectors into the appropriate QSFP28 ports on your network devices, ensuring correct alignment and full seating until the retention latch engages. Use the 1 m length to connect adjacent rack units or neighbouring switch ports to minimise excess cabling. Verify link negotiation and network interface settings on connected devices after physical installation. Follow manufacturer guidelines for hot-plugging if supported by your equipment to avoid unintended network interruptions.

Recommendations

For reliable operation, route the cable to avoid sharp bends and stress on the connectors, maintain recommended minimum bend radius, and keep the cable away from sources of electromagnetic interference. Use this 1 m QSFP28 InfiniBand cable for short-distance, high-bandwidth links where low latency and compact cable management are priorities.
