## Summary description

The BlueOptics SFP28-DAC-3M-MA-BL is a 3-meter SFP28 DAC cable designed for high-speed data transmission. It features male connectors on both ends, ensuring compatibility with SFP28 ports. Ideal for connecting switches and servers in data centers, it offers reliable performance and low latency.

## Long description

The BlueOptics SFP28-DAC-3M-MA-BL is a 3 meter passive SFP28 direct-attach cable (DAC) with SFP28 male connectors on both ends. Designed for short-reach, high-speed data links, this twinax copper cable supports 25GBase-CR electrical signaling for connections between switches, servers and storage systems that accept SFP28 DAC modules. The cable is MSA-compliant and intended for rack-to-rack or within-rack interconnects where low latency and low power consumption are required.
Advantages
The cable provides a simple, low-latency physical link for 25 Gbit/s Ethernet and other supported protocols without active electronic components in the cable itself, which keeps power consumption and failure points minimal. Passive twinax design offers cost-effective short-distance connectivity while adhering to MSA mechanical and electrical specifications. The 3 m length allows flexible placement in rack environments where equipment is adjacent or in neighboring racks.
Suitable for
25G Ethernet links between switches and servers
Short-distance connections inside or between adjacent racks
Storage system interconnects and SAN top-of-rack links
Environments requiring low-latency, low-power direct copper connections
Key specifications
Cable type: passive twinax copper (DAC)
Connector type: SFP28 male to SFP28 male
Data rate support: up to 25 Gbit/s
Length: 3 meters
Wire gauge: 30 AWG
Colour: Black
Weight: 0.08 kg
Standards compliance: MSA electrical/mechanical profile for SFP28 DACs
How to use
Insert each SFP28 connector into the corresponding SFP28 port on networking equipment until it latches. Ensure both devices support passive SFP28 DACs and the chosen transmission protocol (for example, 25GBase-CR) before powering active equipment. Route the cable to avoid sharp bends and mechanical strain; maintain a minimum bend radius appropriate for twinax copper cabling. For best results, verify link status and negotiated speed via device management after connection.
Usage recommendations
Use this 3 m passive SFP28 DAC for short-reach links where cost efficiency and low latency are priorities. Confirm compatibility with the hardware vendor’s SFP28 DAC policy and, where possible, test a sample in your environment to validate interoperability and performance.
