Lightwin 25G SFP28 to SFP28 Direct Attach Copper Cable, 3m, Passive, 30AWG, LSZH LWO-DAC-SFP28-3M

Experience 25 Gigabit Ethernet connectivity with this Lightwin SFP28 Direct Attach Copper (DAC) cable, delivering a full 25 Gbps data rate over a 3-meter passive copper link. Engineered for data centers, server-to-switch uplinks, and SAN environments, it offers a cost-effective, low-latency alternative to optical transceivers while maintaining full MSA compliance and multi-vendor compatibility.

Overview

The Lightwin LWO-DAC-SFP28-3M is a passive Direct Attach Copper cable terminated with SFP28 connectors on both ends. It supports 25GbE per IEEE 802.3by, with a characteristic impedance of 100 Ohm and minimal power consumption below 0.5W. The 30AWG copper conductors ensure signal integrity over the 3-meter length, while the LSZH jacket provides safety in high-density installations. Hot-pluggable and built to operate in temperatures from 0°C to 70°C, this cable is ready for demanding network environments.
