## Summary description

Copper breakout cable CBO 40G-QSFP-4SFP-PC-0301-BL is a 3 m QSFP to 4×SFP+ male assembly designed for linking a 40Gb QSFP port to four 10Gb SFP+ ports. Suitable for data center and networking equipment interconnects, it enables port splitting, direct server or switch connections, and simplifies upgrades or reconfiguration without transceivers.

## Long description

Copper breakout cable CBO 40G-QSFP-4SFP-PC-0301-BL is a 3 m QSFP to 4×SFP+ male assembly designed to connect a single 40Gb QSFP port to four separate 10Gb SFP+ ports. The passive copper design enables direct electrical connectivity between compatible switches, servers and other networking devices without the need for optical transceivers. This cable is intended for short-reach interconnects in data centers, server rooms and network aggregation points where port splitting or consolidation is required.
Advantages
The cable provides a compact and cost-effective way to split one 40Gb link into four 10Gb links using a single assembly, reducing the need for additional modules and simplifying cabling. Its passive copper construction eliminates the need for external power and lowers latency compared with active optics for short distances. The fixed 3 m length offers predictable signal behavior and straightforward installation for top-of-rack and adjacent-rack connections.
Suitable for
Splitting a 40Gb QSFP port into four 10Gb SFP+ ports for switches and routers
Direct connections between servers and switches without transceivers
Short-reach interconnects in data centers and server rooms
Network reconfiguration and temporary test setups
Key specifications
Cable type: QSFP to 4×SFP+ breakout (copper)
Connector configuration: one QSFP male to four SFP+ male
Data rate support: 40 Gbps aggregated, 10 Gbps per lane
Length: 3 meters
Construction: passive copper direct-attach assembly
Usage environment: short-reach, within-rack and adjacent-rack connections
How to use
Power off or follow live-insert guidance from your equipment vendor before connecting. Insert the QSFP end into the 40Gb QSFP port and plug the four SFP+ ends into the target 10Gb SFP+ ports. Ensure that devices support passive copper breakout assemblies and that port mapping or breakout mode is configured on the switch or host as required. Confirm link status and speed on each 10Gb port after installation.
Usage recommendations
Use this passive copper breakout cable for short distances up to the fixed 3 m length; avoid extended runs beyond intended reach. Verify hardware compatibility and any required port or breakout settings on network equipment before installation. Handle connectors carefully to avoid bending or contaminating contacts and keep the cable routed to prevent strain on connectors.
