## Summary description

Direct-attach copper (DAC) cable CBO BN-QS-QS-CBL-2M-BL, 2 meters, with QSFP connectors at both ends. Designed for short-range high-speed interconnects between QSFP ports in switches, routers and servers. Provides low-latency, power-efficient connection for data center links and server switch uplinks, simplifying rack-level cabling.

## Long description

The CBO DAC cable BN-QS-QS-CBL-2M-BL is a 2 meter direct-attach copper (DAC) assembly with QSFP connectors on both ends, intended for short-range, high-speed interconnects between QSFP ports in switches, routers and servers. This passive copper cable provides a low-latency, power-efficient physical link for rack-level connections in data centers and server rooms, simplifying cabling for uplinks and device-to-device connections.
Advantages
This QSFP to QSFP DAC cable delivers predictable signal performance with minimal latency and negligible power draw compared with optical transceivers. Its fixed 2 m length reduces excess cable slack in racks and helps maintain organized, high-density cabling. The copper construction eliminates the need for separate transceivers, lowering component count and simplifying installation and maintenance while providing consistent electrical characteristics suitable for short reach QSFP interconnects.
Suitable for
 Rack-level uplinks between switches and aggregation devices
 Direct connections between servers and top-of-rack switches
 High-density switch-to-switch links within the same rack or adjacent racks
 Short-reach connections in data center and colocation environments
Key specifications
 Connector type: QSFP on both ends
 Cable type: Direct-attach copper (DAC), passive
 Length: 2 meters
 Use case: Short-range, high-speed interconnects
 Latency: Low electrical latency suitable for uplinks and server connections
 Power: Passive copper with minimal additional power consumption compared to optical solutions
How to use
Install the DAC cable by inserting each QSFP connector into compatible QSFP ports until the latch engages. Ensure devices are powered down or support hot-plugging according to vendor guidance, then verify link status in the switch or server management interface. Route the cable cleanly within the rack to avoid sharp bends and maintain recommended bend radius. For relocation or replacement, depress the connector latch and remove the cable straight out to avoid strain on the port.
Usage recommendations
Verify QSFP port compatibility and supported speeds on both devices before deployment. Use the 2 m QSFP to QSFP DAC cable for short-range links where passive copper meets required signal integrity and where reduced latency and power usage are priorities. Avoid excessive bending or mechanical stress and keep the cable away from heat sources or sharp edges to preserve performance and service life.
