Product information

Description

The Direct Attach Cable (DAC) CBO JNP-25G-DAC-50CM is a passive SFP28 twinax assembly designed for short-reach 25Gb/s links. At 50 cm length, this BlueOptics cable connects SFP28-compatible switches, servers and NICs with low latency and minimal power consumption. It is intended for dense data-center topologies and rack-to-rack or server-to-switch interconnects where short, reliable copper connections are required.

Advantages

This passive SFP28 twinax cable offers a compact physical footprint and reliable 25Gb/s performance without the need for external power. The fixed 50 cm length reduces cable clutter and simplifies cable management in crowded racks. Low signal attenuation and built-in shielding deliver consistent throughput and reduced electromagnetic interference, while the direct attach design eliminates the cost and complexity of separate transceivers.

Suitable for

  • Short-reach connections between switches and servers in data centers
  • Direct links to network interface cards (NICs) supporting SFP28
  • Top-of-rack and end-of-row cabling in high-density rack environments
  • Upgrading or expanding 25GbE uplinks and aggregation links

Key specifications

  • Connector type: SFP28 twinax direct attach
  • Data rate: 25 Gb/s per port
  • Cable length: 50 cm
  • Cable type: Passive copper twinax
  • Latency: low, suitable for server and switch interconnects
  • Shielding: integrated shielding for reduced EMI

How to use

Insert the SFP28 plugs into the SFP28 ports of compatible switches, servers or NICs until the latch clicks into place. Ensure both ends are fully seated and matched to SFP28 ports rated for 25Gb/s operation. No additional power or configuration is required for the cable itself; verify link negotiation and interface settings on connected devices through network management tools to confirm established connectivity and correct speed settings.

Usage recommendations

Use this 50 cm passive DAC for short intra-rack or short inter-rack links where 25Gb/s performance and minimal latency are priorities. Avoid sharp bends and excessive pulling; maintain bend radius as specified by the equipment vendor. For longer runs or flexible cabling needs, consider active optical or longer-range copper solutions.
