## Summary description

Direct attach copper (DAC) cable CBO CBL-QSFP-4x10GSFP-PASS-1M is a 1-meter passive breakout cable with a QSFP plug on one end and four 10G SFP+ connectors on the other. Designed for short-range connectivity between switches, routers and servers, it supports 40G to 4×10G split links, simplifies cabling and reduces power compared with active optics in rack-level interconnects.

## Long description

Direct attach copper (DAC) cable CBO QSFP to 4x10G SFP+ CBL-QSFP-4x10GSFP-PASS-1M is a 1-meter passive breakout cable featuring a single QSFP connector on one end and four 10G SFP+ connectors on the other. It provides a straightforward electrical connection for short-range links in rack environments, enabling a 40G port to be split into four independent 10G channels. The passive construction minimizes power consumption and simplifies installation for top-of-rack and aggregation switch interconnects.
Advantages
This passive DAC cable offers low-latency, energy-efficient connectivity without the need for optical transceivers or additional power. The compact one-meter length reduces cable clutter in dense rack deployments and the breakout design enables flexible port mapping between high-density QSFP ports and 10G SFP+ interfaces. Passive copper construction also typically provides a cost-effective solution for short-reach links compared with active or optical alternatives.
Suitable for
Interconnects between switches and aggregation devices within the same rack
Connecting server NICs with 10G SFP+ ports to a 40G QSFP uplink
Short-range inter-switch links in data centre top-of-rack deployments
Lab environments and test benches requiring 40G-to-4x10G breakout
Key specifications
Connector type: QSFP (one end) to 4 × SFP+ (other end)
Function: Passive direct attach breakout cable
Supported link split: 40G to 4 × 10G
Cable length: 1 metre
Transmission medium: Copper twinax
Typical use range: Short-reach / within-rack connections
How to use
Insert the QSFP connector into the 40G QSFP port on the switch or device and insert the SFP+ connectors into the corresponding 10G ports on the target devices. Ensure the host ports support breakout operation (40G to 4×10G) and that the devices are powered down or have hot-swap capability if required by your hardware vendor. Verify link status and negotiate speed on each 10G interface after connection. Avoid excessive bending and keep the cable clear of hot components to maintain signal integrity.
Usage recommendations
Use this passive DAC cable for short-distance, intra-rack connections where energy efficiency and low latency are priorities. Confirm switch and server compatibility for QSFP-to-4xSFP+ breakout and observe vendor guidelines for supported breakout modes and maximum cable lengths.
