## Long description

The BlueOptics SFP28 DAC Cable SFP28-DAC-0.5M-AT-BL is a 0.5 m passive direct attach twinax copper cable with male SFP28 connectors on both ends. Designed for short-reach, high-speed links in data center racks and adjacent rack connections, it supports 25GBase-CR electrical transmission and follows MSA mechanical and electrical guidelines to ensure interoperability with compatible network equipment. The cable has a 30 AWG twinax conductor and is intended for low-latency, low-power connections between switches, servers and storage devices.
Advantages
This SFP28 DAC cable provides reliable 25 Gbit/s data transmission over short distances with minimal latency and low power consumption. Compliance with SFP28 MSA specifications ensures mechanical fit and electrical compatibility with devices that support passive DACs. Passive twinax construction reduces component complexity and failure points, offering a simple, maintenance‑friendly interconnect with an expected long service life when used within specified conditions.
Suitable for
Top-of-rack and adjacent-rack connections in data centers
Direct server-to-switch or switch-to-switch links requiring 25G bandwidth
Storage system interconnects and converged Ethernet/FCoE links
Short-distance high-performance networking within racks
Key specifications
Length: 0.5 meters
Connector type: SFP28 male to SFP28 male
Data rate: up to 25 Gbit/s
Cable type: passive twinax copper (DAC)
Conductor gauge: 30 AWG twinax
Standards: SFP28 MSA compliant
Typical power consumption: low (passive module)
How to use
Insert each SFP28 connector into the appropriate SFP28 port on network devices until the latch engages, taking care to align the connector orientation with the port key. Use the cable for short point-to-point links inside racks or between adjacent racks; confirm that both devices support passive DAC cables and the 25GBase-CR protocol before deployment. Avoid excessive bending of the cable near the connectors and secure the cable to prevent strain on the SFP28 cages.
Usage recommendations
Verify device compatibility and firmware settings for passive DAC support and 25G operation. Route the cable to minimize EMI exposure and avoid sharp bends (maintain manufacturer minimum bend radius). For inventory and spare planning, consider ordering test samples to validate interoperability in your specific hardware environment.
