## Summary description

Direct attach copper (DAC) passive breakout cable by CBO, model 40G-QSFP-4SFP-C-0101-BL. 1 m length with a QSFP connector on one end and four SFP+ female interfaces on the other, supporting 40 Gbps aggregation via four 10 Gbps SFP+ links. Designed for short-reach connections between switches, servers and storage in data centers; offers low latency and plug-and-play installation.

## Long description

BlueOptics DAC passive cable CBO 40G-QSFP-4SFP-C-0101-BL is a 1 m direct attach copper breakout cable that connects a single QSFP port to four SFP+ ports. The cable provides 40 Gbps aggregation by carrying four independent 10 Gbps SFP+ links over a single QSFP connector, enabling compact, short-reach interconnects between switches, servers and storage in data center topologies. Its passive copper construction delivers low latency and plug-and-play operation without the need for external power or transceivers.
Advantages
The passive DAC design offers low latency and predictable performance suitable for high-density environments. A 1 m length minimizes signal loss for short-reach connections while reducing rack clutter compared with multiple separate cables. The breakout format lets one QSFP port act as four SFP+ interfaces, simplifying aggregation and migration paths from 10 Gbps to 40 Gbps uplinks. The cable’s fixed assembly requires no additional modules or configuration, supporting immediate deployment.
Suitable for
 Aggregation of four 10 Gbps links into a 40 Gbps QSFP uplink between switches
 Direct short-reach connections from servers or storage to top-of-rack or spine switches
 High-density patching in rack environments where space and cable management are important
 Environments where low latency and plug-and-play installation are required
Key specifications
 Connector configuration: one QSFP connector to four SFP+ female interfaces
 Data rate: supports aggregated 40 Gbps via four independent 10 Gbps lanes
 Medium: passive copper direct attach cable (DAC)
 Length: 1 meter
 Colour: black
 Use case: short-reach, within-rack or adjacent-rack connections
How to use
Insert the QSFP connector into the QSFP port on the aggregation device and plug the four SFP+ female ends into the corresponding SFP+ ports on target devices, verifying port alignment and latch engagement. No transceivers or external power sources are required; the cable is recognized as a passive direct attach connection by compatible network equipment. After physical installation, check link status and port speed on switch or server management interfaces to confirm four active 10 Gbps links and overall 40 Gbps aggregation where supported.
Usage recommendations
The cable is intended for short-reach, within-rack or adjacent-rack links; avoid using it for long-haul connections. Verify compatibility with your switch and server hardware for passive DAC support and ensure ports are rated for SFP+ and QSFP breakout operation before deployment.
