What This Solves
High-Density Rack Interconnects
In modern data centers, optimizing rack space and port utilization is crucial for operational efficiency. This cable enables a single 40Gbps QSFP+ port to connect to four 10Gbps SFP+ devices, consolidating links and simplifying cabling within server racks.
Data center operators, co-location facilities, enterprise infrastructure teams, large-scale virtualized environments
Server-to-Switch Connectivity
Connecting multiple 10GbE network interface cards (NICs) on a server to a high-speed 40GbE switch uplink can be complex and costly with individual transceivers. This direct attach cable provides a cost-effective and low-latency solution for linking servers to top-of-rack switches.
IT operations teams, network operations centers, infrastructure management, private cloud deployments
Network Aggregation & Breakout
Organizations often need to aggregate lower-speed links into a higher-speed backbone or break out a high-speed link to multiple lower-speed devices. This cable facilitates efficient 40Gbps to 4x 10Gbps breakout, supporting flexible network segmentation and bandwidth allocation.
Campus networks, remote office deployments, metro-area infrastructure, core network upgrades

Frequently Asked Questions
What is the primary application of this breakout cable?
This cable is primarily used to connect a single 40Gbps QSFP+ port on a network switch or server to four separate 10Gbps SFP+ ports on other devices, facilitating high-density, short-reach interconnects within a data center rack.
Is this cable compatible with non-Cisco networking equipment?
While specifically tested for Cisco compatibility, this cable also complies with MSA (Multi-Source Agreement) industry standards, which generally ensures broad interoperability with other brands of networking equipment that adhere to these standards.
What are the advantages of using a passive direct attach copper (DAC) cable over active optical cables (AOCs)?
Passive DACs like this one are more cost-effective, consume less power, and have lower latency than AOCs for short distances (typically up to 7 meters), making them ideal for intra-rack connectivity.
Can this cable be used for distances longer than 5 meters?
This specific cable is 5 meters in length. While DAC technology can extend slightly further, passive copper cables are generally limited to short distances (up to 7 meters) for reliable 40Gbps performance. For longer distances, active optical cables or fiber optic transceivers are recommended.
