Description

The QSFP-4SFP25G-CU1M is a 1-meter long Direct Attach Copper (DAC) cable designed for high-speed interconnects in data centers and high-performance computing environments. It allows users to connect QSFP+ devices to SFP28 devices and is used for 40GbE to 25GbE connectivity.

Key Features:

• Data Rate: 40 Gbps (via QSFP+ side) and 25 Gbps (via SFP28 side)

• Length: 1 meter (3.3 feet)

• Cable Type: Passive Copper Cable (DAC)

• Connector Type: QSFP+ on one side and 4 x SFP28 on the other side, allowing for multiple connections from a single cable.

• Application: Designed for 40GbE to 25GbE interconnection, allowing one QSFP+ port on a switch or server to connect to four 25GbE SFP28 ports.

Applications:

• Data Center Interconnects: Connecting QSFP+ switches to SFP28-based servers, storage, or other networking devices within a data center.

• High-Performance Computing (HPC): Used for high-density, short-range connectivity where devices require 25GbE or 40GbE connections.

• Server Rack Connections: Interconnecting devices that require multiple 25G ports to a single 40G port, simplifying cable management and reducing clutter.

Benefits:

• Cost-Effective: The DAC cable offers a lower-cost alternative to fiber optic cables, especially for short-range connections (1 meter).

• High Density: The QSFP+ to 4 x SFP28 configuration allows for 4 separate 25GbE connections from a single port, increasing port efficiency and simplifying connections.

• Low Latency: Provides low-latency performance for time-sensitive applications such as real-time data processing and data replication.

• Plug-and-Play: No additional configuration or external power is required, making it easy to install and use in a network.
