Product information

Description

The BlueOptics SFP28 Direct Attach Cable 25GBASE-CR, 5 m is a passive copper twinax assembly designed for direct electrical connectivity between SFP28 ports. It supports 25GBASE-CR signaling for short-reach 25 Gbps links and is tailored for deployments in data center racks, server rooms and network closets where low-latency, high-bandwidth electrical connections are required. The cable integrates SFP28 connectors on both ends and a fixed 5-metre length for straightforward point-to-point links without separate transceivers.

Advantages

The direct attach cable provides a cost-effective alternative to optical transceivers for short-distance 25 Gbps interconnects, reducing power consumption and simplifying installation. Its passive twinax construction ensures reliable electrical performance with minimal signal loss across the specified 5 m span. The integrated SFP28 connectors eliminate the need for additional module housings, streamlining cable management in dense rack environments.

Suitable for

  • Connecting SFP28 ports on switches and top-of-rack devices
  • Direct links between servers and network interface cards (NICs)
  • Short-reach interconnects inside data center racks and server cabinets
  • High-density 25 Gbps patching in aggregation and spine-leaf fabrics

Key specifications

  • Standard: 25GBASE-CR electrical interface
  • Connector type: SFP28 integrated twinax
  • Length: 5 metres (fixed)
  • Cable type: Passive copper twinax assembly
  • Nominal data rate: 25 Gbps per link
  • Typical use: Short-reach/rack-level interconnects

How to use

Install the cable by inserting each SFP28 connector into the corresponding SFP28 port on your network devices until the latch engages. Ensure both ends are fully seated and that the devices are powered down or follow hot-plug procedures recommended by the device manufacturer. Verify link status and speed in the device management interface after installation. For best results, route the cable to avoid tight bends and maintain proper airflow in the rack.

Usage recommendations

Use this BlueOptics SFP28 direct attach cable for short-distance 25G interconnects where passive twinax delivers lower cost and power compared with optical solutions. Avoid exceeding the specified 5 m distance and prevent repeated tight bending or crushing of the cable to preserve signal integrity and connector longevity.
