## Summary description

The BlueOptics SFP28-DAC-3M-IB-BL is a 3-meter SFP28 Direct Attach Copper cable designed for high-speed data transmission. It features male connectors on both ends, ensuring a reliable connection for networking equipment. Ideal for data centers and high-performance computing environments, this cable provides a cost-effective solution for short-distance connections.

## Long description

The BlueOptics SFP28-DAC-3M-IB-BL is a 3-meter SFP28 Direct Attach Copper (DAC) cable with SFP28 male connectors on both ends. Designed for short-distance, high-speed connections, this passive twinax copper cable supports 25G data rates and complies with SFP28 MSA electrical and mechanical interface specifications. The cable is intended for use in rack-to-rack and within-rack links in data centers and high-performance computing environments where a reliable, low-latency copper connection is required.
Advantages
This SFP28 DAC cable provides a cost-effective alternative to optical transceivers and fiber for short links, offering low power consumption and low latency due to its passive twinax design. The 3 m length is suitable for adjacent racks or within-rack connections and simplifies installation because it uses direct SFP28-to-SFP28 plugs. Built and tested to MSA-compatible specifications, the cable aims for broad interoperability with hardware that supports passive SFP28 DACs and is produced using high-quality components for consistent performance.
Suitable for
Short-distance 25G connections between switches and routers in data center racks
Direct links between servers and top-of-rack switches
High-performance computing nodes requiring low-latency links
Storage systems and network equipment that support SFP28 DAC passive connections
Key specifications
Connector type: SFP28 male to SFP28 male
Length: 3 meters
Transmission rate: up to 25 Gbps per link
Cable type: passive twinax copper (30 AWG conductors)
MSA-compatible SFP28 electrical and mechanical interface
Typical use: short-reach direct attach connections in rack environments
How to use
Install the cable by inserting each SFP28 connector into the corresponding SFP28 port on the networking devices until the latch engages. Ensure both devices support passive SFP28 DAC connections and the same transmission protocol (for example 25G Ethernet or compatible storage/network protocols). Route the 3 m cable to avoid sharp bends and mechanical stress; secure it within the rack to prevent strain on connectors. No external power or configuration on the cable itself is required, but verify link status and device settings after connecting.
Usage recommendations
Confirm hardware compatibility with passive SFP28 DACs and check vendor documentation for supported cable types before deployment. For optimal reliability, avoid tight bends (keep bend radius within manufacturer guidance), minimize mechanical stress on the connectors, and perform a link test after installation.
