Product information

Description

The BlueOptics QFX-SFP-DAC-2M-BL is a 2‑meter SFP+ direct-attach cable (DAC) designed for short-range high-speed connectivity in rack and adjacent-rack environments. This passive twinax copper cable conforms to 10GBase-CR and SFP+ MSA standards and provides a straightforward SFP+ to SFP+ connection for switches, routers and storage devices that support passive DAC modules. The cable is intended for electrical signal transfer over short distances with predictable latency and low power draw.

Advantages

This 2 m BlueOptics SFP+ DAC delivers 10 Gbps link rates while remaining passive (no external power required), which reduces power consumption and latency compared with active optical modules. Its twinax copper construction and 30 AWG wiring offer stable electrical transmission for short connections in racks. The cable is manufactured to industry MSA specifications and is compatible with major networking platforms that support 10GBase-CR passive DAC cabling.

Suitable for

  • Connecting SFP+ ports between switches within the same rack or adjacent racks
  • Direct links between servers and top-of-rack switches
  • Short-distance storage area network (SAN) connections using Fibre Channel or FCoE over SFP+
  • InfiniBand or Ethernet 10 Gbps links where passive DAC is supported

Key specifications

  • Type: Passive SFP+ direct-attach cable (twinax copper)
  • Length: 2 meters
  • Connector: SFP+ male to SFP+ male
  • Data rate: up to 10 Gbps
  • Cable gauge: 30 AWG
  • Standards: 10GBase-CR, SFP+ MSA compliant
  • Typical applications: Ethernet, FCoE, Fibre Channel, InfiniBand (up to 10 Gbps)

How to use

Verify that both endpoints support passive SFP+ direct-attach cables and that their SFP+ ports are enabled. Insert each SFP+ connector firmly into the corresponding port until the latch engages. Route the 2 m twinax cable within the rack to avoid sharp bends and mechanical strain on connectors. After insertion, check link status on connected devices and configure interfaces as required by your network or storage operating system.

Usage recommendations

Use this 2 m passive SFP+ DAC for short, fixed connections inside racks where predictable latency and low power use are priorities. Avoid exceeding recommended bend radius, and ensure connected hardware explicitly supports passive DACs to guarantee compatibility. For distances beyond a few meters or when optical isolation is required, consider active optical modules instead.
