## Summary description

The BlueOptics SFP28-DAC-3M-SW-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-SW-BL is a 3‑meter Direct Attach Copper (DAC) cable with SFP28 male connectors at both ends, designed for 25G data links in rack and adjacent‑rack installations. As a passive twinax copper cable it implements 25GBase‑CR electrical signalling over a short 3 m distance and is suitable for connecting SFP28 ports on switches, servers and storage systems that support passive DAC modules. The cable is supplied in black and weighs approximately 0.08 kg.
Advantages
The cable provides low latency and low power consumption typical for passive twinax DACs, with a compact, fixed‑length design that simplifies short‑distance connections inside data center racks. MSA‑compliant electrical and mechanical interfaces ensure interoperability with hardware supporting SFP28 DAC modules. The 30 AWG twinax conductor and passive construction reduce points of failure and support reliable operation for common 25G Ethernet, FCoE and similar protocols at 3 m reach.
Suitable for
Direct connections between switches in the same or adjacent rack
Server-to-switch links in data center topologies
Storage system connections that accept SFP28 DACs
Short‑reach 25G Ethernet, FCoE and comparable applications
Key specifications
Cable type: Passive twinax copper (DAC), SFP28 to SFP28
Length: 3 meters
Data rate support: up to 25 Gbit/s per channel (25GBase‑CR)
Conductor gauge: 30 AWG
Compliance: MSA‑compliant SFP28 electrical/mechanical interface
Colour: Black
Typical use case: short‑distance rack interconnects
Weight: ~0.08 kg
How to use
Install the BlueOptics SFP28‑DAC‑3M‑SW‑BL by inserting each SFP28 male connector into the corresponding SFP28 socket on your networking devices until the latch engages. Ensure both devices officially support passive SFP28 DAC cables and that firmware or software settings do not block third‑party passive DAC modules. No external power or setup is required; the cable carries electrical signalling between ports when connected and the devices are powered on. For removal, depress each latch and withdraw the connector straight out to avoid damaging the port.
Usage recommendations
Use this 3 m passive DAC for short, fixed point‑to‑point links inside racks or between adjacent racks. Avoid routing the cable near sources of strong electromagnetic interference and do not bend the cable tightly; observe the manufacturer’s minimum bend radius. Confirm device compatibility and, where available, test a sample link before deploying across production systems.
