Product information

Description

The BlueOptics QSFP-40G-CU2M-BL InfiniBand Fibre Optic Cable 2m Male-Male is a 2-meter direct-attach twinax copper cable with QSFP-to-QSFP male connectors designed for short-range 40G connections in racks and between adjacent racks. Compliant with MSA recommendations and built with 30 AWG conductors, this cable supports 40GBase-CR4 electrical signaling for Ethernet, FCoE, Fibre Channel and InfiniBand applications. It is intended for use where reliable, low-latency, and power-efficient 40 Gbps links are required in data centers and network equipment that support QSFP passive direct attach cables.

Advantages

The cable offers passive direct-attach operation with low power consumption and minimal latency, providing a cost-effective option for short-distance 40G connectivity. Manufactured from quality components and tested for compatibility with major hardware platforms, it aims to deliver long service life and stable performance. Its QSFP-to-QSFP connectors and MSA-compatible construction enable straightforward installation and interoperability across supporting devices.

Suitable for

  • 40 Gbps links between switches inside the same rack or adjacent racks
  • High-throughput server-to-switch and switch-to-storage connections
  • Ethernet, FCoE, Fibre Channel and InfiniBand short-reach links
  • Environments requiring low-latency, low-power interconnects

Key specifications

  • Connector type: QSFP (male) to QSFP (male)
  • Length: 2 meters
  • Data rate: up to 40 Gbps
  • Cable type: passive twinax copper (DAC), 30 AWG
  • Signaling: 40GBase-CR4 compatible
  • Compliance: MSA-compatible design for QSFP DAC use
  • Typical power consumption: very low (passive cable, ~0.1 W typical system-level)

How to use

Install the BlueOptics QSFP-40G-CU2M-BL by inserting each QSFP male connector into compatible QSFP ports on switches, routers, servers or storage systems while ensuring the host hardware supports passive 40G DAC cables. Route the 2 m cable to avoid sharp bends and mechanical strain; gentle loops with a radius larger than the cable diameter are recommended. After physical connection, verify link status and negotiate speed and protocols through the connected devices' management interfaces. No separate power source or transceiver modules are required for passive operation.

Usage recommendations

Use this cable for short-reach, rack-to-rack or intra-rack 40G links in data centers and ensure that the connected equipment officially supports passive QSFP twinax DACs. Avoid exposing the cable to excessive bending, tensile stress, or electromagnetic interference, and confirm interoperability with a test sample if required by your hardware vendor.
