## Summary description

Direct attach copper (DAC) cable CBO 9370CM40GCAB2-0030 is a 40G QSFP high-speed connectivity solution for short-range interconnects. Supplied in a 0.3 m length, it provides a low-latency, energy-efficient link between QSFP ports in switches, servers and storage systems. Ideal for rack-to-rack or intra-rack connections where a short, reliable 40 Gbps copper link is required.

## Long description

CBO DAC Cable 9370CM40GCAB2-0030 is a 40G QSFP direct attach copper (DAC) cable designed for short-range, high-throughput interconnects. At 0.3 m length, this BlueOptics cable delivers a low-latency copper link between QSFP ports in switches, servers and storage systems. It provides a compact and energy-efficient option for short-distance 40 Gbps connections inside racks or between adjacent racks where optical transceivers are unnecessary.
Advantages
The direct attach copper construction ensures low latency and predictable signal integrity for 40 Gbps links while eliminating the need for separate transceivers. Its fixed 0.3 m length reduces clutter and simplifies cable management in dense rack environments. As a passive copper solution, it offers lower power consumption compared with active optical options and straightforward plug-and-play installation with standard QSFP ports.
Suitable for
 Short-range connections between QSFP-enabled switches and routers
 Direct links between servers and top-of-rack switches
 High-density rack-to-rack or intra-rack 40 Gbps interconnects
 Data center aggregation and leaf-spine architectures requiring short copper runs
Key specifications
 Interface type: QSFP to QSFP direct attach copper
 Rated data rate: 40 Gbps
 Length: 0.3 m
 Cable medium: copper twinax
 Latency: low, suitable for latency-sensitive short links
 Power: passive (no external power required)
 Compatibility: QSFP ports in switches, servers and storage appliances supporting 40G DAC
How to use
Ensure both devices support QSFP 40G direct attach copper connections. Align the QSFP connectors and insert each end firmly into the corresponding QSFP port until the latch engages. No additional configuration is required for basic link establishment; connected devices will negotiate the 40 Gbps link according to their port settings. For replacement or reinstallation, power down or follow hot-swap procedures recommended by the equipment vendor if required, then gently disengage the latch and remove the cable.
Usage recommendations
Use this 0.3 m DAC cable for short, fixed-length connections where optical transceivers are not needed. Avoid tight bends and excessive pulling; maintain bend radius recommended for twinax copper to preserve signal integrity. Verify device firmware and port compatibility with 40G QSFP DACs before deployment.
