Network DAC Cable CBO QSFPMM2M-BL 30 m — BlueLAN direct-attach copper, compatible with SFP+ ports

The BlueOptics Network DAC Cable CBO QSFPMM2M-BL 30 m is a direct-attach copper (DAC) cable engineered for short-range, high-speed links between SFP+ ports. Designed to provide a reliable electrical connection over a 30-m distance, this BlueLAN cable is suitable for data center topologies and rack-to-rack interconnects where low latency and cost efficiency are required. The cable supports typical SFP+ bandwidths and is compatible with devices that accept copper direct-attach modules, with passive or active operation determined by the connected equipment.

Advantages

This 30 m DAC cable reduces the need for optical transceivers and separate fiber patching, lowering overall deployment cost and simplifying rack cabling. The copper direct-attach design delivers low latency and stable signal integrity across short distances, which is beneficial for server-to-switch and switch-to-switch connections. The integrated cable assembly and robust jacket in blue make identification and routing easier in dense cabling environments.

Suitable for

• Short-range high-speed links between SFP+ ports in data centers
• Server-to-switch and switch-to-switch interconnects inside racks
• Storage system connections requiring low latency
• Environments where cost-effective alternatives to fiber are preferred

Key specifications

• Cable type: direct-attach copper (DAC)
• Length: 30 m
• Connector interface: SFP+ compatible electrical connectors
• Bandwidth support: suitable for SFP+ 10 Gbit/s links (device dependent)
• Jacket color: blue for easy identification
• Construction: integrated cable assembly with molded connectors

How to use

Install the DAC cable by inserting each SFP+ compatible connector into the corresponding SFP+ port on the devices to be linked. Ensure both endpoints support copper direct-attach connections; the cable will function as passive or active depending on device compatibility. Route the cable to avoid tight bends and excessive strain on the connectors, and secure it within the rack to maintain orderly cabling. Verify link status through device LEDs or management interfaces after connection.

Recommendations

For reliable operation, confirm equipment compatibility with direct-attach copper cabling and verify transceiver settings where applicable. Use the cable for connections within the specified 30 m range and avoid sharp bends or prolonged exposure to high temperatures. Label both ends for inventory and maintenance to simplify future changes.
