Product information

Description

The BlueOptics 40GB-C0.5-QSFP-BL is a 0.5 m InfiniBand/fibre optic direct attach cable with QSFP to QSFP male connectors designed for high-speed short-distance links in racks and adjacent rack systems. It supports up to 40 Gbit/s data rates and is intended for use in data center environments and network hardware that accept QSFP direct attach solutions. Its compact length and passive twinax/twin-axial design make it suitable for short, low-latency connections between switches, routers and storage devices.

Advantages

The cable provides a straightforward physical connection for 40G applications with QSFP interfaces, offering low latency and low power consumption typical of passive direct attach cabling. Manufactured to align with industry MSA guidelines, the product is built from established component vendors and is intended to deliver dependable electrical signal transfer over a short 0.5 m distance. Its short form factor simplifies cable management in dense rack environments.

Suitable for

  • 40G QSFP interconnects between switches and routers in rack and adjacent rack setups
  • Server to switch or storage to switch short links within data centres
  • InfiniBand, Ethernet, Fibre Channel and FCoE applications that operate over 40G direct attach cabling

Key specifications

  • Connector type: QSFP male to QSFP male
  • Cable length: 0.5 m
  • Data rate: up to 40 Gbit/s
  • Cable type: passive direct attach (twinax copper / twin-axial electrical transmission)
  • Form factor: 40GBase-CR4 compatible

How to use

Ensure both devices support 40G QSFP direct attach passive cables and have matching QSFP ports. With devices powered down or following hot-plug guidance from the hardware vendor, align each QSFP connector with the port and insert until it seats securely. Confirm link establishment in the host hardware or switch management interface and verify correct speed and protocol operation (Ethernet, InfiniBand, Fibre Channel or FCoE) according to your network configuration. Handle the cable by the connector housings and avoid sharp bends to maintain signal integrity.

Usage recommendations

Use this 0.5 m BlueOptics QSFP direct attach cable for short interconnects where passive twinax is supported by the hardware. Verify vendor compatibility lists for the target switches, routers or storage systems before deployment and avoid exceeding manufacturer-recommended bend radii and stress on the connectors to ensure reliable long-term operation.
