QSFP na 4x SFP+ breakout kábel CBO 40G-QSFP-4SFP-PC-0301-BL 3 m — QSFP 4x SFP+ samec

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.

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.
