## Summary description

Direct-attach copper (DAC) cable CBO 9370CM40GCAB0-0030 is a 40Gbps QSFP passive copper interconnect designed for short-range high-speed links. With a 0.3 m length, it connects QSFP ports between switches, routers or servers, providing low-latency, cost-effective connectivity for data center top-of-rack and aggregation use cases.

## Long description

Direct-attach copper (DAC) cable CBO 9370CM40GCAB0-0030 is a 40Gbps QSFP passive copper interconnect with a 0.3 m length, designed for short-range, high-speed links. It provides a simple, low-latency physical connection between QSFP ports on switches, routers and servers. The cable supports 40 Gigabit Ethernet links in data centre top-of-rack and aggregation deployments where a short, reliable copper connection is required.
Advantages
The cable delivers a full 40Gbps data rate over a short fixed-length passive copper assembly, ensuring minimal signal conversion and low latency. Its compact 0.3 m length reduces cabling clutter in dense racks and simplifies port-to-port connectivity without the need for transceivers or additional modules. Passive construction lowers power consumption compared with active copper or optical alternatives and offers cost-effective performance for short reach connections.
Suitable for
Top-of-rack switch to server or switch connections in data centres
Short-range aggregation links between networking devices
High-density rack environments where space and cable management are critical
Environments prioritising low-latency interconnects for compute or storage clusters
Key specifications
Data rate: 40 Gbps
Connector type: QSFP (quad small form-factor pluggable) direct-attach copper
Cable type: Passive copper twinax assembly
Length: 0.3 m
Typical use: Short-reach interconnects within racks or between adjacent equipment
Latency: Low, due to direct copper connection without optical conversion
How to use
Install the DAC cable by aligning the QSFP connectors with the device ports and inserting until the retention latch engages; no external power or configuration is required for the passive assembly. Ensure both ends are seated in compatible QSFP ports on the devices being connected and confirm link status via the device management interface. Route the 0.3 m cable to avoid sharp bends and to maintain cable management standards within the rack.
Usage recommendations
Use this passive QSFP DAC cable for links within the same rack or between adjacent racks where the 0.3 m length and 40 Gbps capacity meet your topology requirements. Avoid using it beyond the recommended short-reach distance; verify port compatibility and firmware support on networking equipment before deployment.
