Product information

Description

The BlueOptics CPAC-DAC-40G-05M-BL is a 0.5 m direct attach cable (DAC) with QSFP connectors on both ends, designed for short-range 40G interconnects in racks and adjacent rack positions. As a passive twinax copper cable (40GBase-CR4, 30 AWG) it carries electrical signals for Ethernet, FCoE, Fibre Channel and InfiniBand up to 40 Gbit/s over a half-metre distance. The cable combines a compact form factor with QSFP-to-QSFP connectivity and a black/silver housing to fit common data‑center hardware.

Advantages

This 0.5 m QSFP-to-QSFP DAC delivers low latency and low power consumption typical for passive twinax cables, while offering high signal integrity for short-distance 40G links. Manufactured to MSA-compliant specifications and using quality components, it is suitable as a cost-effective alternative to branded direct-attach cables and aims for long service life and high availability in professional environments.

Suitable for

  • Interconnecting QSFP ports inside racks and between adjacent racks
  • 40G Ethernet, FCoE and Fibre Channel short-reach links
  • InfiniBand connections for compute and storage clusters
  • Switch-to-switch, switch-to-server and switch-to-storage links

Key specifications

  • Cable type: Passive twinax (DAC), 40GBase-CR4
  • Connector type: QSFP to QSFP, male/male
  • Length: 0.5 m
  • Wire gauge: 30 AWG
  • Performance: Supports up to 40 Gbit/s over 0.5 m
  • Colour: Black and silver housing
  • Weight: Approximately 0.15 kg

How to use

Ensure both endpoints support passive QSFP DACs and the intended 40G protocol. Power down or follow hot‑swap procedures recommended by your hardware vendor before insertion if required. Align each QSFP connector with the device port and press until the latch engages. Verify link status on connected devices and configure network settings or protocols (Ethernet, FCoE, Fibre Channel, InfiniBand) as needed. For removal, release the connector latch and pull straight out to avoid stressing ports.

Usage recommendations

Use this direct attach cable for short, high-speed connections where passive twinax is supported. Avoid sharp bends and excessive pull force; maintain a minimum bend radius consistent with the cable construction. For critical deployments, test compatibility with your switch, router or storage platform and consider requesting a sample to validate operation within your environment.
