SFP+ Direct Attach Cable BlueOptics 747522101 10GBASE-CR 1 m

BlueOptics 747522101 SFP+ Direct Attach Cable is a pre-terminated passive copper cable designed for short-range 10 Gigabit Ethernet links. With SFP+ form-factor connectors on both ends and a 1 m length, this 10GBASE-CR DAC provides a direct electrical connection between compatible SFP+ ports in racks, switches and servers. The cable is intended for use in dense networking environments where low latency and low power consumption are required for server-to-switch and switch-to-switch interconnects.

Advantages

The direct-attach construction eliminates the need for separate transceivers and fiber patch cords, resulting in a lower overall link cost and reduced insertion loss. Passive copper design yields minimal latency and lower power draw compared with optical alternatives for the same link distance. The standardized SFP+ form factor ensures broad compatibility with equipment that supports 10GBASE-CR SFP+ copper cables, and the fixed 1 m length simplifies cabling in rack-mounted and cabinet installations.

Suitable for

• Server-to-switch connections in data center racks
• Switch-to-switch short-range uplinks in network cabinets
• Top-of-rack (ToR) interconnects requiring 10 Gbps throughput
• High-density patching where low latency and low power are priorities

Key specifications

• Interface: SFP+ form-factor on both ends
• Data rate: 10 Gigabit Ethernet (10GBASE-CR)
• Cable type: Passive copper direct attach
• Length: 1 meter
• Typical use: Short-range rack and cabinet interconnects

How to use

Install the SFP+ connectors into the SFP+ ports of the two devices to be linked, ensuring the connectors latch securely. Route the 1 m cable to avoid sharp bends and mechanical stress; allow slack to prevent strain on the ports. After insertion, verify link status and negotiated speed on both devices according to the switch or server management interface. No additional modules or transceivers are required since the cable is pre-terminated in SFP+ format.

Usage recommendations

Use this DAC for short intra-rack and adjacent-rack 10G connections. Avoid running the cable near high-power electrical sources and maintain bend radii recommended by the equipment manufacturer. Confirm device compatibility with SFP+ passive copper cables before deployment and test link stability after installation.
