Cabo breakout CBO 40G-QSFP-4SFP-PC-0101-BL 1m QSFP para 4× SFP+ macho

Breakout Cable CBO 40G-QSFP-4SFP-PC-0101-BL, 1m QSFP to 4× SFP+ Male is a copper direct-attach cable designed to connect a single QSFP port to four SFP+ ports. It provides a direct electrical connection for 40G to 4×10G configurations, enabling aggregation or splitting of a 40 Gigabit link into four 10 Gigabit lanes. The compact one-meter length suits short-reach interconnection inside racks or between adjacent network devices such as switches, servers and transceivers.

Advantages

This breakout cable supports reliable high-speed electrical connections without additional transceivers, reducing hardware complexity and power consumption. Its fixed four-lane mapping preserves signal integrity for 40G-to-10G conversion and minimizes latency. The one-meter copper assembly simplifies cable management in dense rack environments and is ready for immediate deployment, requiring no separate fiber patching or module installation.

Suitable for

• Aggregating a 40G QSFP port into four 10G SFP+ links for network distribution
• Connecting switches and servers within the same rack or adjacent racks
• Short-reach links for data center top-of-rack or spine-leaf architectures
• Lab testing and validation of 40G-to-10G port configurations

Key specifications

• Interface: QSFP (male) to 4 × SFP+ (male)
• Cable type: Copper direct-attach breakout cable
• Data rate: Supports 40 Gbit/s aggregated; four independent 10 Gbit/s lanes
• Length: 1 meter
• Use case: Short-reach electrical interconnection
• Application: Switch-to-switch, switch-to-server, or transceiver interconnects

How to use

Insert the QSFP end into the 40G QSFP port on your network device and plug each SFP+ connector into the corresponding 10G SFP+ ports on the target devices. Ensure devices are powered down or follow hot-plug guidelines recommended by the equipment vendor when connecting or disconnecting. Verify lane mapping and port settings in device firmware or operating system to confirm the 40G-to-10G breakout is recognized and configured as required.

Recommendations

Use this cable for short, intra-rack or adjacent-rack connections where a low-latency, low-power electrical solution is preferred. Keep cable runs within the specified length and avoid sharp bends to maintain signal integrity; follow your network equipment vendor's compatibility list for optimal interoperability.
