## Summary description

Passive copper DAC cable CBO QSFP-40G-C2M, 2 meters length, with QSFP+ connectors at both ends supporting 40 Gb/s links. Designed for short-reach, high-throughput connections between compatible switches, routers and network adapters. Provides low-latency, power-efficient direct-attach connectivity in data centers and server racks for aggregation and spine-leaf links.

## Long description

Passive copper DAC cable CBO QSFP-40G-C2M is a 2-metre direct-attach cable with QSFP+ connectors at both ends, engineered for 40 Gb/s links between compatible network devices. The cable provides a short-reach, low-latency physical connection suitable for use inside racks and across adjacent racks in data centre environments. As a passive twinax assembly, it delivers power-efficient connectivity without the need for optical transceivers, enabling high-throughput aggregation and spine-leaf links with minimal configuration.
Advantages
This QSFP+ to QSFP+ cable offers reliable 40 Gb/s performance with low latency and reduced power consumption compared with active/transceiver-based links. Its 2 m length is optimized for short interconnects in server racks and top-of-rack switches, simplifying cabling and reducing signal loss. The passive design eliminates the need for separate optical modules, lowering component count and simplifying inventory while maintaining signal integrity for compatible equipment.
Suitable for
Short-reach connections between QSFP+ ports in the same rack or adjacent racks
Aggregation and spine-leaf links in data centres
Interconnects between switches, routers and network adapters supporting 40 Gb/s
High-throughput server-to-switch connections requiring low latency
Key specifications
Connector type: QSFP+ to QSFP+
Data rate: 40 Gb/s
Length: 2 m (passive copper twinax)
Link type: Direct attach, short-reach
Latency: low, suitable for high-performance networking
Power: passive design reduces power consumption compared with optical transceivers
How to use
Install the cable by inserting each QSFP+ connector firmly into the corresponding port on compatible switches, routers or network adapters until the connector latch engages. Ensure both ends are connected to QSFP+ ports rated for 40 Gb/s and verify link status through device LEDs or management interfaces. No additional optical modules or transceivers are required. For removal, release the connector latch and pull the connector straight out to avoid damaging the port.
Usage recommendations
Use this passive QSFP+ cable for short, direct connections inside racks and between adjacent racks. Avoid sharp bends and keep bend radius within manufacturer guidelines. Confirm compatibility with device firmware and port specifications before deployment, and maintain proper airflow around networking equipment to ensure thermal stability.
