## Summary description

Direct Attach Cable (DAC) by BlueOptics for SFP+ ports, compliant with 10GBASE-CR standard and 5 meters in length. Designed for short-range 10 Gbps connections between switches, servers or network appliances. Passive copper assembly in blue sheath provides low-latency, cost-effective connectivity for data center uplinks and top-of-rack deployments.

## Long description

Direct Attach Cable BlueOptics 10GBASE-CR SFP+ 5 m Blue is a passive copper twinax assembly designed for short-range 10 Gbps links between SFP+ ports. The 5 m length and SFP+ connectors make it suitable for direct connections between switches, servers and network appliances in data center top-of-rack or cabinet environments. The cable uses a blue sheath for easy identification and provides low-latency, energy-efficient connectivity that adheres to the 10GBASE-CR electrical standard.
Advantages
This BlueOptics DAC delivers low latency and consistent signal integrity for 10 Gbps SFP+ links while eliminating the need for separate transceivers. The passive copper construction offers lower power consumption and reduced heat compared with active optical or powered transceiver solutions. The fixed 5 m length simplifies cable management and the colored sheath improves visibility and organization in dense racks.
Suitable for
 Short-range switch-to-switch connections within a rack or adjacent racks
 Server uplinks to top-of-rack switches
 Interconnects between network appliances and storage controllers
 High-density data center deployments requiring cost-effective 10 Gbps links
Key specifications
 Interface: SFP+ to SFP+
 Data rate: 10 Gbps
 Standard: 10GBASE-CR (electrical twinax)
 Length: 5 meters
 Cable type: Passive copper twinax
 Sheath color: Blue
 Typical use: Short-reach direct-attach connections
How to use
Insert each SFP+ connector into the corresponding SFP+ port on networking equipment until the latch engages. Ensure both devices support passive 10GBASE-CR DACs and are powered off or follow hot-plug guidelines recommended by the equipment manufacturer when connecting live. After insertion, verify link status and negotiated speed in the device management interface. Route the cable to avoid sharp bends and mechanical stress on the connectors.
Usage recommendations
Use this DAC for short, cost-sensitive 10 Gbps interconnects inside racks or between adjacent racks. Avoid running the cable near high-electromagnetic-interference sources and do not exceed recommended bend radius or pull force. For longer runs or fiber-optic environments, consider optical transceivers and fiber cabling instead.
