What This Solves
High-Density Rack Interconnects
Data centers and server rooms require high-speed, short-distance connections between network switches and servers within the same rack or adjacent racks. This 1-meter QSFP+ to 4x SFP+ DAC cable provides a direct, cost-effective link, enabling 40Gbps uplinks to be broken out into four 10Gbps server connections.
Data center operators, co-location facilities, enterprise infrastructure teams, campus network administrators
Server-to-Switch Connectivity
Organizations need to connect multiple 10Gbps network interface cards (NICs) in servers to a single high-density 40Gbps switch port. The cable facilitates this breakout connection, allowing four individual servers or storage devices to share a single 40Gbps switch port, optimizing port utilization.
IT operations teams, virtualized environments, database clusters, high-performance computing (HPC) setups
Network Upgrade & Expansion
Businesses are upgrading their network backbone to 40Gbps but still have existing 10Gbps SFP+ equipment that needs to integrate. This passive DAC provides a flexible and hot-pluggable solution to bridge the gap, allowing for phased upgrades without immediate replacement of all 10Gbps devices.
Growing mid-market companies, organizations with mixed network speeds, IT departments managing infrastructure lifecycle

Frequently Asked Questions
What type of network equipment is compatible with this cable?
This cable is compatible with any network equipment featuring MSA-compliant QSFP+ ports for 40Gbps connections and SFP+ ports for 10Gbps connections, including switches, routers, and network interface cards.
Can this cable be used for longer distances than 1 meter?
No, this is a 1-meter passive Twinax Direct Attach Cable designed specifically for short-distance, in-rack connections. For longer distances, active optical cables (AOCs) or fiber optic transceivers would be required.
Does this cable require any special drivers or configuration?
As a passive direct attach cable, it is plug-and-play and does not require any special drivers, software, or complex configuration, simplifying deployment for IT teams.
What is the benefit of a passive Twinax cable over active optical cables (AOCs)?
Passive Twinax cables are more cost-effective, consume less power, and have lower latency than AOCs, making them ideal for short-reach, high-speed connections within a data center rack.
