100Gbps QSFP28 To 4x SFP25G Breakout Cable Low Latency DAC Cisco Cables And Accessories
100Gbps QSFP28 To 4x SFP25G Breakout Cable Low Latency DAC Cisco Cables And Accessories
The Cisco QSFP-4SFP25G-CU3M is a high-performance Direct Attach Copper (DAC) breakout cable, designed to deliver 100Gbps (4x25G) connectivity with ultra-low latency for modern data centers and enterprise networks. This QSFP28 to 4x SFP28 cable enables flexible high-density deployments, allowing a single 100G port to split into four independent 25G connections—ideal for spine-leaf architectures, cloud computing, and storage networks.
Key Features & Benefits
✅ 100Gbps Breakout Support – Converts 1x QSFP28 (100G) port into 4x SFP28 (25G) ports, optimizing switch port utilization.
✅ Low-Latency DAC Design – Passive copper cable ensures faster signal transmission than optical solutions, reducing power consumption.
✅ Plug-and-Play Installation – No external power or configuration required; hot-swappable for easy deployment.
✅ Cost-Effective 100G Solution – Eliminates the need for separate transceivers and fiber, reducing TCO.
✅ 3-Meter Reach – Perfect for rack-to-rack or ToR (Top-of-Rack) server connections.
✅ Cisco Certified & Reliable – Fully tested for compatibility with Cisco Nexus 9000/3000, UCS, and more.
