## Summary description

Direct Attach Copper (DAC) cable CBO JNP-QSFP-DAC-0.5M-BL is a 0.5 m passive QSFP Male-to-Male assembly supporting 40 Gbit/s data rates. Designed for short-distance, high-bandwidth connections between switches, routers or servers with QSFP ports. Provides low latency, power-efficient interconnect and simple plug-and-play installation in data center and network rack environments.

## Long description

Direct Attach Copper (DAC) cable CBO JNP-QSFP-DAC-0.5M-BL is a 0.5 m passive QSFP Male-to-Male assembly designed for 40 Gbit/s connections. The cable delivers a short-reach, high-bandwidth link between network devices equipped with QSFP ports and is suited for dense rack and data center environments where low latency and power efficiency are required.
Advantages
The passive copper construction provides low latency and reduced power consumption compared with optical transceivers. Its 0.5 m length minimises signal loss for short interconnect runs while keeping cable management simple. The QSFP male-to-male connectors offer plug-and-play compatibility with QSFP ports, enabling quick installation without additional modules or configuration. The cable is suitable for high-throughput traffic and keeps thermal load low in constrained rack spaces.
Suitable for
Interconnects between switches in the same rack
Connections between routers and aggregation switches
Server uplinks to top-of-rack switches
High-density data centre patching and short-distance links
Key specifications
Connector type: QSFP male-to-male
Data rate: up to 40 Gbit/s
Cable type: passive direct attach copper (DAC)
Length: 0.5 m
Form factor: QSFP interface for four-lane aggregation
Typical use: short-reach, high-bandwidth interconnect
How to use
Install the cable by inserting each QSFP connector into the corresponding QSFP port on the devices until the connector latches. Ensure both devices are powered and that ports support 40 Gbit/s QSFP passive copper assemblies. No additional modules or transceivers are required. Verify link status through device management interfaces and monitor traffic to confirm expected throughput.
Usage recommendations
For reliable operation, avoid sharp bends and excessive tension on the cable; maintain minimum bend radius as recommended for copper assemblies. Use this 0.5 m DAC cable for intra-rack and short inter-rack connections where cable length limits are met. In environments requiring longer runs or optical isolation, consider appropriate active or optical alternatives.
