QSFP-4SFP25G-CU1M Cisco 1m QSFP28 to 4x25G SFP28 Passive Copper Breakout Cable

The QSFP-4SFP25G-CU1M cable is commonly deployed in data center environments where network administrators need to optimize port density and manage high-throughput connections efficiently. It is particularly suited for IT teams overseeing virtualization platforms or enterprise-grade storage networks requiring multiple 25G links from a single 100G interface.

How It's Used:

• Breaking out a 100G uplink from a core switch into four separate 25G connections to access top-of-rack switches in large-scale data centers.
• Enabling network segmentation in enterprise IT environments by providing dedicated 25G links to different server clusters from a single QSFP28 port.
• Supporting high-performance computing workloads by connecting compute nodes that require multiple 25G interfaces for distributed processing tasks.
• Facilitating edge computing deployments where compact and power-efficient cabling solutions reduce infrastructure complexity.
• Integrating storage clusters with multi-path connectivity by splitting one 100G port into several 25G channels for redundancy and load balancing.

This breakout cable enhances operational flexibility by allowing network architects to scale bandwidth allocation without additional transceiver modules. Its passive design simplifies cabling schemes and reduces power consumption, supporting efficient network expansion in dense rack and virtualization setups.
