BlueOptics 40G-QSFP-C-0301-BL InfiniBand optický kábel 3 m konektor samec/konektor samec

The BlueOptics 40G-QSFP-C-0301-BL InfiniBand fibre optic cable 3 m Male/Male is a 3-metre direct attach solution with QSFP-to-QSFP connectors designed for 40G links in racks and adjacent rack rows. It provides a compact, factory-terminated connection intended for short-distance high-speed data transmission in data centres and networking environments. The cable is suitable for applications that require reliable 40G connectivity between switches, routers, storage systems and other compatible hardware that support QSFP 40G interconnects.

Advantages

This cable delivers a standardized QSFP end-to-end connection for 40G InfiniBand and Ethernet-compatible links with low latency and minimal power consumption. Its 3 m length is optimized for rack-to-rack or within-rack connections, simplifying installation and cable management. Manufactured to MSA-compliant specifications and assembled from quality components, it provides stable electrical performance for short reach direct-attach usage and is intended to meet the requirements of major hardware platforms that support QSFP 40G connections.

Suitable for

• 40G links between rack-mounted switches and adjacent racks
• High-performance InfiniBand and Ethernet connections in data centres
• Interconnects between switches, routers and storage arrays that accept QSFP direct attach
• Short-reach top-of-rack and spine-to-leaf cabling

Key specifications

• Connector type: QSFP to QSFP, Male/Male
• Length: 3 metres
• Supported data rate: up to 40 Gbps per link
• Cable type: direct attach twinax copper (passive DAC) designed for short-distance electrical transmission
• Typical use: rack and adjacent rack interconnects with low latency and low power consumption

How to use

Install the cable by inserting each QSFP connector into the corresponding QSFP port on your network devices until the latch engages. Ensure both devices support passive QSFP direct attach twinax copper connections and the intended 40G protocol (Ethernet, FCoE, Fibre Channel or InfiniBand) before powering the links. Route the cable to avoid tight bends and mechanical strain; keep it clear of heat sources and high-traffic areas. If a device does not detect the connection, verify port compatibility, link settings and that the cable is fully seated.

Recommendations

Use this 3 m QSFP direct attach cable for short-reach links inside racks or between adjacent racks where a cost-effective, low-latency 40G connection is required. Confirm hardware compatibility with QSFP passive DACs and follow manufacturer guidance for insertion/removal to preserve connector and port integrity.
