Key Features

QSFP+ to 4 x SFP+ breakout design
Copper cable construction
5 m cable length
Supports 40 GbE to 4 x 10 GbE fan-out
Direct passive-style interconnect for breakout use
Suitable for high-density rack deployments

Turn one high-speed uplink into four usable 10 GbE connections with a fan-out copper cable designed for breakout deployments. This 5 m QSFP+ to 4 x SFP+ assembly is a practical fit for switch-to-server, switch-to-storage, and aggregation scenarios where a single 40 GbE port must feed multiple 10 GbE interfaces. The value is in efficient port utilization. Instead of dedicating separate uplinks for each endpoint, this cable lets teams map one QSFP+ port to four SFP+ connections with a direct copper path. That can simplify rack design, reduce the number of active components in the signal chain, and make it easier to scale incrementally without overbuilding the fabric. At 5 m, it is long enough for common rack and adjacent-rack layouts while staying manageable in dense enclosures. For teams balancing performance, cost control, and operational clarity, this breakout cable offers a clean way to extend the life of existing 10 GbE infrastructure while using 40 GbE switch capacity more efficiently.

Ideal For

Connecting one 40 GbE switch port to four 10 GbE servers
Breakout from aggregation switches to multiple access devices
Storage or appliance connectivity where four SFP+ links are needed
In-rack and adjacent-rack breakout cabling in enterprise data centers

Frequently Asked Questions

What does a fan-out cable do?▾

It splits one high-speed QSFP+ port into multiple SFP+ connections, allowing one uplink to serve four endpoints.

What speeds does this cable support?▾

It is designed for 40 GbE on the QSFP+ side and four 10 GbE connections on the SFP+ side.

Is 5 m enough for rack deployments?▾

Yes. Five meters is commonly used for in-rack and adjacent-rack breakout runs.

Why use a copper fan-out cable instead of separate optics?▾

It simplifies cabling, reduces component count, and provides a direct path for breakout connections.
