## Long description

BlueOptics SFP+ Direct Attach Cable 10GBASE-CR, 3 m is a factory-terminated copper twinax cable engineered for short-reach 10 Gigabit Ethernet connections. The cable implements the 10GBASE-CR specification and provides a fixed 3-metre link between SFP+ ports in switches, servers and other network appliances. It is intended to deliver a low-latency, energy-efficient and cost-effective physical link for top-of-rack and server-to-switch interconnects in data centre and enterprise environments.
Advantages
The direct attach design offers predictable electrical performance and minimal latency compared with optical transceivers plus fiber. A fixed 3 m length eliminates the need for separate transceivers and LC patch cords, reducing component count and cabling complexity. The SFP+ form-factor ensures compatibility with standard SFP+ ports and enables hot-pluggable installation. The copper construction typically yields lower power consumption and lower overall cost for short-distance 10 Gbps links.
Suitable for
Top-of-rack switch to server 10 Gbps connections
Server-to-switch interconnects in data centres
Short-reach links between SFP+ ports in network appliances
Consolidated cabling in rack-mounted infrastructure
Key specifications
Interface: SFP+ to SFP+
Standard support: 10GBASE-CR
Data rate: 10 Gbps
Cable type: Twinax copper assembly
Fixed length: 3 metres
Form factor: Hot-pluggable SFP+ connector

How to use
Insert each SFP+ connector into the corresponding SFP+ port on the networking devices until the module latches. Ensure both devices support SFP+ direct-attach copper links and are configured for 10 Gbps operation. After physical installation, verify link status and speed in the device management interface; if necessary, adjust port settings or firmware to enable the 10GBASE-CR link. Handle the cable by the connectors and avoid excessive bending of the cable to maintain signal integrity.
Usage recommendations
Use this 3 m SFP+ direct attach cable where a stable, low-latency 10 Gbps connection is required within a single rack or between adjacent racks. Confirm vendor compatibility when connecting devices from different manufacturers and avoid using this copper cable for distances beyond the specified 3 m.
