Product information

Description

Passive SFP28 Direct Attach Copper Cable CBO SFP28-DAC-0.5M is a 0.5 m fixed-length twinax cable designed for short-reach 25GbE or SFP28 connections. Manufactured by BlueOptics, this passive DAC provides a direct wired link between SFP28 ports on switches, routers and network interface cards (NICs). It requires no external power, supports plug-and-play installation and is intended for reliable rack-to-rack or intra-rack connectivity where low latency and signal integrity are required.

Advantages

The cable offers a compact, low-latency connection with minimal installation effort and no additional power source. Its passive design reduces operational complexity and the short 0.5 m length minimizes signal attenuation and crosstalk for short-distance interconnects. Being a direct attach solution, it eliminates the need for transceivers and fiber patching for compatible SFP28 ports.

Suitable for

  • Short-reach 25GbE links between switches in the same rack
  • Direct connections between routers and NICs that support SFP28
  • Intra-rack server-to-switch interconnects with SFP28 ports

Key specifications

  • Connector type: SFP28 direct attach copper (twinax) compatible
  • Length: 0.5 m
  • Data rate: 25 Gbps class (for SFP28 links)
  • Design: Passive (no external power required)
  • Use case: Short-reach, rack-to-rack or intra-rack connectivity

How to use

Insert each SFP28 connector into the corresponding SFP28 port on the devices to be linked, ensuring proper seating and latch engagement. Verify that both endpoints support passive SFP28 direct attach copper cables and that compatible link settings are configured on connected network equipment. No additional transceivers, power adapters or fiber patch cords are required. After installation, monitor the link status through the devices' management interfaces to confirm successful negotiation and operation.

Usage recommendations

Use this 0.5 m passive DAC for short-distance links within the same rack or adjacent racks. Avoid bending the cable sharply, exposing it to excessive mechanical stress or exceeding the supported operating conditions of the connected equipment. Confirm compatibility with your switch or server vendor for passive SFP28 DACs before deployment.
