Direct Attach Copper (DAC) Cable CBO BlueOptics DAC10G-3M-BL 3 m SFP+ 10 Gbit/s

The Direct Attach Copper (DAC) Cable CBO BlueOptics DAC10G-3M-BL 3 m SFP+ 10 Gbit/s is a pre-terminated copper twinax assembly with SFP+ male connectors designed for short-reach, high-speed links. It connects SFP+ ports on switches, servers and storage appliances to provide 10 Gbit/s full-duplex data transfer with low latency and minimal setup. The 3 meter length suits typical rack-to-rack and within-rack interconnects in data centers and network closets where cost-effective, energy-efficient connectivity is required.

Advantages

This DAC cable offers plug-and-play operation with SFP+ compatible ports, eliminating the need for separate transceivers and simplifying installation. The fixed copper assembly delivers stable 10 Gbit/s performance with low latency and low power consumption compared with active optical options for short distances. Its robust SFP+ male terminations and molded strain relief reduce risk of connector damage during handling and maintenance.

Suitable for

• Short-range server-to-switch connections inside racks
• Top-of-rack and end-of-row interconnects in data centers
• Interlinking storage appliances and networked storage systems
• High-density switch-to-switch links in wiring cabinets

Key specifications

• Connector type: SFP+ male to SFP+ male
• Cable type: Direct Attach Copper (twinax passive)
• Maximum data rate: 10 Gbit/s (full duplex)
• Length: 3 m
• Typical use case: short-reach interconnects (within or between racks)
• Latency: low, suitable for time-sensitive traffic

How to use

Insert each SFP+ connector into the SFP+ port on the two devices to be connected, ensuring the latch engages and the connector is seated fully. Verify link lights and network interface status on both devices to confirm a successful 10 Gbit/s connection. For initial deployment, check device compatibility settings if link negotiation is required. When removing the cable, press the connector latch before pulling to avoid damaging the port or cable.

Usage recommendations

Use this cable for short, fixed interconnects in controlled environments; avoid routing near sources of strong electromagnetic interference and do not exceed the recommended bending radius to maintain signal integrity. Store the cable coiled without tight loops when not in use, and inspect connectors for debris before insertion.
