## Summary description

Direct Attach Cable (DAC) BlueOptics Hirschmann 942 280-004 is a 10 Gigabit twinaxial SFP+ copper interconnect designed for short-range high-speed links between switches, servers and NICs. As a passive SFP+ twinax cable it provides low-latency, low-power connectivity for data center top-of-rack, aggregation and server-to-switch connections where fiber transceivers are not required.

## Long description

Direct Attach Cable BlueOptics 10 Gigabit Twinaxial SFP+ is a passive SFP+ twinax copper interconnect designed for short-range 10 Gbps links between network equipment. The cable provides a direct electrical connection for switches, servers and network interface cards (NICs) in rack environments where fiber transceivers are unnecessary. Intended for data center top-of-rack and server-to-switch connections, this 10 Gigabit twinaxial SFP+ solution emphasizes low latency and low power consumption while maintaining the physical simplicity of a copper cable assembly.
Advantages
This Direct Attach Cable offers fixed 10 Gbps bandwidth with minimal signal conversion, resulting in reduced latency compared with optical links that require transceivers. As a passive twinax SFP+ assembly, it consumes no additional power for active signal conversion and simplifies installation with a single, pre-terminated connector pair. The copper construction provides cost-effective short-reach connectivity and predictable electrical characteristics suitable for dense rack deployments.
Suitable for
 Top-of-rack switch to server 10 Gigabit connections
 Aggregation links within the same rack or adjacent racks
 Direct server NIC to switch interconnects for low-latency applications
 Short-distance connections in data centers where fiber is not required
Key specifications
 Data rate: 10 Gigabit Ethernet (10 Gbps)
 Connector type: SFP+ electrical twinax interface
 Cable type: Twinaxial copper
 Form factor: SFP+ direct attach (fixed-connector assembly)
 Range: Designed for short-range, rack-level interconnects
 Latency: Low latency typical of direct electrical links
 Power: Passive design with minimal additional power use
How to use
Plug one SFP+ connector into the SFP+ port of the switch or NIC and insert the opposite connector into the receiving device’s SFP+ port until the latch engages. Ensure both devices support SFP+ direct attach cables and are configured for 10 Gigabit operation. Route the cable to avoid tight bends and mechanical strain; maintain the recommended bend radius for twinax copper assemblies. After physical connection, verify link status through the devices’ management interfaces and confirm negotiated speed and duplex settings.
Usage recommendations
Use this cable for short, high-density connections inside racks or between adjacent racks. Avoid prolonged exposure to excessive mechanical stress, and do not exceed the recommended bend radius. Verify compatibility with your network equipment’s SFP+ port compatibility list to ensure proper link up and diagnostics.
