Direct Attach SFP+ Cable CBO SFP-10G-DAC-0.5M-NU-BL 0.5m 10Gbit/s

BlueOptics Direct Attach SFP+ Cable CBO SFP-10G-DAC-0.5M-NU-BL is a 0.5 metre fixed-length passive copper cable that supports 10 Gbit/s data rates between SFP+ ports. It is intended for short-range interconnects inside racks and equipment cabinets, providing a direct wired link that removes the need for separate transceivers. The cable is compatible with standard SFP+ port form factors and offers a compact, low-latency connection for networking equipment.

Advantages

This 0.5 m SFP+ direct attach cable delivers low power consumption and minimal latency compared with optical transceivers and fiber assemblies. The fixed-length design simplifies cable management in dense rack environments and reduces the number of replaceable parts by eliminating separate pluggable transceivers. Its metal-reinforced SFP+ connectors provide reliable mating with switches, servers and storage devices and help maintain consistent signal integrity for short-range high-speed links.

Suitable for

• Top-of-rack switch to server connections
• Blade chassis internal links
• High-speed uplinks within the same rack or adjacent racks
• Short-distance storage area network (SAN) interconnects

Key specifications

• Connector type: SFP+ to SFP+
• Length: 0.5 metre
• Data rate: up to 10 Gbit/s
• Cable type: passive copper direct attach
• Typical use range: short-range, intra-rack connections

How to use

Insert each SFP+ connector into the corresponding SFP+ port until it clicks into place, ensuring correct orientation. Use the cable to connect compatible networking equipment such as switches, servers or storage arrays. No external power or configuration is required for basic link operation; the host devices negotiate link parameters over the SFP+ interface. Verify link status on attached equipment and secure the cable routing to avoid strain on the connectors.

Recommendations

Use this 0.5 m direct attach cable for connections within the same rack or between adjacent racks to maintain low latency and reduced power consumption. Avoid stretching the cable or bending it sharply near the connectors, and ensure the mating ports are compatible with SFP+ passive DAC assemblies. For longer distances or different data rate requirements, consider optical transceivers or active cables designed for extended reach.
