## Summary description

CBO 740-038625 is a 5-meter Direct Attach Cable (DAC) with QSFP connectors, designed for short-range high-speed connections between networking devices. As a passive copper cable, it provides a cost-effective, low-latency link suitable for switches, routers and servers supporting QSFP interfaces. Use it for rack-to-rack or within-rack interconnects where electrical DACs are supported.

## Long description

The BlueOptics Direct Attach Cable (DAC) CBO 740-038625 is a 5 m passive copper cable with QSFP connectors, intended for short-range, high-speed interconnects between network equipment. Designed for environments where low latency and cost efficiency are important, this DAC supports direct electrical connections between compatible QSFP ports on switches, routers and servers. The cable is suitable for rack-to-rack or within-rack links where passive QSFP assemblies are supported.
Advantages
This passive QSFP copper assembly provides a reliable, low-latency connection with minimal power consumption because it requires no active optical components. The fixed 5 m length simplifies cable management for common rack layouts while avoiding the need for separate transceivers. As a direct attach solution, it reduces overall hardware and operational costs compared with active optical modules for similar short-reach applications.
Suitable for
 Short-reach links between switches and routers within the same rack or adjacent racks
 Interconnects between servers and top-of-rack or end-of-row switches
 Data centre patching where QSFP ports and electrical DACs are supported
Key specifications
 Cable type: passive copper direct attach cable with QSFP connectors
 Length: 5 meters
 Interface: QSFP form-factor electrical connection for high-speed links
 Typical applications: short-distance, high-throughput interconnects in racks and data centres
 Latency: low (electrical connection, no active optical conversion)
How to use
Insert each QSFP connector into the corresponding QSFP port on the network devices until the connector latches; ensure connectors are aligned and fully seated. Route the cable to avoid sharp bends and mechanical stress; maintain recommended bend radius for copper assemblies. Verify link status on device interfaces and configure port settings as required for the network speed and protocols in use. For safe removal, release the connector latch before unplugging to prevent damage to ports or cable.
Usage recommendations
Use this passive QSFP DAC for short-range interconnects up to 5 m where devices explicitly support QSFP electrical direct attach cables. Avoid using the cable in environments with excessive vibration, high temperatures or where electromagnetic interference could affect performance. Keep connectors clean and free from dust when not connected.
