Product Description
This breakout cable is designed to split one 40Gbps QSFP+ port into four independent 10Gbps SFP+ connections, enabling flexible network configurations without additional hardware. It's commonly used in data centers or enterprise networks where scalable, high-speed connectivity is essential. Often found in environments needing to connect high-bandwidth switches or servers with multiple 10Gbps interfaces, this cable simplifies infrastructure by consolidating connections. Key Features Provides four separate 10G SFP+ connections from a single QSFP+ port Passive copper design reduces power consumption and complexity Supports Cisco devices ensuring seamless integration 2-meter length offers flexibility for rack and cabinet setups Delivers reliable, low-latency data transfer ideal for demanding applications Typically deployed in data center top-of-rack switches or aggregation layers, this breakout cable helps optimize port usage and lowers costs by eliminating the need for additional transceivers. Its reliable performance supports workloads requiring consistent, fast connections across multiple 10Gbps links.

Use Cases
The QSFP-4SFP10G-CU2M breakout cable is primarily utilized in high-density networking environments where efficient port aggregation and segmentation are critical. It serves enterprise IT teams and data center operators requiring consolidated 40Gbps uplinks that can be split into multiple 10Gbps connections for downstream switches or servers. How It's Used: Data center top-of-rack (ToR) switches distributing high-bandwidth traffic to multiple 10Gbps server ports. Enterprise network backbones needing flexible segmentation of 40Gbps uplinks to connect legacy 10Gbps SFP+ devices. Virtualization infrastructure where multiple 10Gbps virtual machines require distinct physical network links from a single 40Gbps interface. Storage area networks (SANs) that demand scalable bandwidth distribution from a consolidated 40Gbps link to individual 10Gbps storage nodes. Edge computing deployments where space constraints favor compact breakout solutions over additional modular hardware. This cable simplifies network architecture by enabling efficient bandwidth allocation and reducing hardware complexity. Its passive design supports low-latency data transfer, making it well-suited for scalable, high-performance network environments.
