## Summary description

The BlueOptics SFP28-DAC-3M-LS-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 secure connection for networking equipment. Ideal for data centers and enterprise networks, this cable provides reliable performance and low latency.

## Long description

The BlueOptics SFP28-DAC-3M-LS-BL is a 3‑meter SFP28 Direct Attach Copper (DAC) cable with SFP28 male connectors on both ends designed for short‑reach, high‑speed links. It implements the 25GBase‑CR electrical interface and uses a passive twinax copper construction with 30 AWG conductors, offering a straightforward solution for connecting switches, routers and storage hardware in racks or between adjacent racks. The cable is MSA‑compliant and intended for environments that require low latency, low power consumption and predictable electrical performance.
Advantages
The cable provides a fixed, low‑latency 25 Gbps channel over a 3 m distance using a passive twinax design that does not require active electronics in the cable itself. Its SFP28 male‑to‑male terminations deliver a secure mechanical fit with standard SFP28 ports. MSA compliance ensures mechanical and electrical interoperability with hardware that supports SFP28 DACs. The cable’s passive nature keeps power draw minimal and the simple construction reduces points of failure for reliable operation in dense data‑center installations.
Suitable for
Short‑reach 25 Gbps connections inside racks or between adjacent racks
Interconnecting SFP28 ports on switches, routers or storage systems
High‑performance ethernet, FCoE, Fibre Channel and InfiniBand links up to 25 Gbps
Data‑center top‑of‑rack and adjacent‑rack cabling where low latency and low power are required
Key specifications
Length: 3 meters
Interface: SFP28 male to SFP28 male
Data rate: up to 25 Gbps per lane
Cable type: Passive twinax copper (DAC), 30 AWG
Standards: 25GBase‑CR electrical interface, MSA compliant
Typical power consumption: very low (passive design)
Color: Blue
How to use
Install the cable by inserting each SFP28 connector into the matching SFP28 port on the two devices to be linked. Ensure both devices officially support passive SFP28 DAC connections and that ports are configured for the appropriate 25G protocol. Avoid sharp bends and excessive pulling on the cable; maintain recommended bend radius for twinax assemblies. For initial deployment, verify link status and throughput in the host equipment management interface to confirm successful negotiation and full 25 Gbps operation.
Usage recommendations
Use this 3 m passive SFP28 DAC for short, fixed connections inside racks or between adjacent racks where cost‑effective, low‑latency cabling is required. Confirm compatibility with your switch or storage vendor and consider requesting a test sample for verification in mixed‑vendor environments.
