## Summary description

The BlueOptics SFP28-DAC-0.5M-PS-BL is a 0.5 meter SFP28 direct attach copper cable with male connectors on both ends. It is designed for high-speed data transmission in data centers and networking applications, providing a reliable and efficient connection between devices.

## Long description

The BlueOptics SFP28-DAC-0.5M-PS-BL is a 0.5 meter passive SFP28 direct attach copper (DAC) cable with SFP28 male connectors on both ends. Designed for short-reach high-speed interconnects, the cable supports 25GBase-CR electrical transmission for linking switches, routers, storage systems and other network devices in racks or between adjacent racks. The cable uses twinax copper construction with 30 AWG conductors and is intended for environments that require low-latency, low-power, and cost-effective short-distance connections.
Advantages
This SFP28 DAC cable provides a compact and reliable physical connection that requires no external transceivers, resulting in lower power consumption and reduced latency compared with optical solutions for short distances. The 0.5 m length minimizes signal attenuation for high-speed 25 Gbit/s links while the passive twinax design keeps implementation and maintenance simple. The product is manufactured to Multi-Source Agreement (MSA) standards for SFP28 form factor interoperability and uses robust components to support long service life in data center deployments.
Suitable for
 Server-to-switch or switch-to-switch connections inside racks
 High-density top-of-rack (ToR) aggregation links
 Short-reach storage networking (e.g., NVMe, FCoE) at 25 Gbit/s
 Low-latency applications and lab test setups
Key specifications
 Cable length: 0.5 m
 Connector type: SFP28 male to SFP28 male
 Supported data rate: up to 25 Gbit/s (25GBase-CR)
 Cable type: passive twinax copper, 30 AWG
 Typical power consumption: passive (near 0.1 W per link when reported by host)
 Colour: black
 Designed for short-reach, rack-level interconnects
How to use
Ensure both network devices support passive SFP28 DAC cables and the 25GBase-CR electrical standard. Insert each SFP28 connector into the corresponding SFP28 port until the latch clicks. Confirm the host devices recognise the link and that ports are configured for the desired speed and protocol (Ethernet, FCoE, or Fibre Channel over the supported interface). For best results, route the cable to avoid sharp bends and mechanical strain; the short 0.5 m length is intended for direct, within-rack connections or adjacent rack placements.
Usage recommendations
Use this passive SFP28 DAC cable for short-distance, high-bandwidth connections where the host hardware explicitly supports passive twinax SFP28 links. Avoid extended runs beyond recommended distances and verify compatibility with your switch or storage vendor prior to deployment. Store and handle the cable in dry conditions and avoid kinking to preserve signal integrity and service life.
