Keep high-speed links simple where distance is measured in racks, not meters. This 3 m passive DAC is designed for 25 GbE SFP28 deployments that need direct, dependable connectivity without the cost and power overhead of optical transceivers. For top-of-rack switching, server uplinks, and short interconnects inside the same cabinet row, passive copper is often the most efficient choice. It delivers the direct attach path infrastructure teams want for dense environments: fewer components, lower latency, and less heat at the port. Cisco-compatible integration makes it a practical fit for mixed-vendor procurement strategies where interoperability matters, but so does budget discipline. At 3 m, it gives you enough reach for adjacent equipment while staying within the performance envelope expected from short DAC runs. Choose this cable when you want to simplify port provisioning, reduce optical spares, and keep 25G links clean and predictable in production racks.
