## Long description

The BlueOptics DAC cable CBO 9370CM40GCAB1-0030 is a passive direct-attach copper (DAC) cable that provides a 40G QSFP connection for short-range, high-throughput links between compatible network devices. Intended for rack-to-rack and within-rack interconnects in data center environments, this cable delivers 40 Gbps bandwidth with low latency and simplified installation by eliminating the need for separate optical transceivers.
Advantages
This 40G QSFP DAC cable offers a cost-effective and power-efficient connectivity option for short-distance links. The passive copper construction reduces energy consumption compared with active or optical solutions and lowers overall system cost by removing transceiver modules. With plug-and-play QSFP terminations, the cable enables quick deployment and minimal setup time while maintaining low latency suitable for aggregation and switching layers.
Suitable for
Rack-to-rack connections within a single data hall
Within-rack uplinks between top-of-rack switches and aggregation switches
High-throughput, short-reach links in enterprise and cloud data centers
Switch-to-switch connections where 40 Gbps links are required
Key specifications
Connector type: QSFP to QSFP
Data rate: 40 Gbps
Cable type: Passive direct-attach copper
Recommended link length: short-range / within-rack and rack-to-rack
Application: Data center switching and aggregation
How to use
Install the DAC cable by inserting each QSFP connector into the corresponding QSFP port on the network devices until the latch engages. Ensure both devices are powered down or follow hot-plug guidance from the device manufacturer if supported. After connection, verify link status through device management interfaces and configure ports for 40 Gbps operation according to your network policy and switch settings.
Usage recommendations
Use this passive 40G QSFP DAC cable for short-distance connections inside racks or between adjacent racks. Avoid routing the cable near sources of electromagnetic interference and do not exceed the recommended link length to maintain signal integrity. Check switch compatibility with passive QSFP DACs and confirm port settings for optimal performance.
