Cavo breakout in fibra CBO QSFP a 4× SFP+ MC2609130-003 3 m nero

The CBO QSFP to 4× SFP+ Fiber Breakout Cable MC2609130-003 3 m Black is a passive multimode fiber assembly that converts one QSFP interface into four independent SFP+ connections. With a 3 meter jacket in black, this breakout cable provides a compact and low-latency solution for splitting a single 40Gb/s QSFP link into four separate 10Gb/s links. It is intended for short-range, high-density connectivity between QSFP-enabled switches, routers or transceivers and multiple SFP+ modules in rack and data center environments.

Advantages

This passive breakout cable offers a simple, cost-effective method to expand port density without additional active converters or transceivers. Its design reduces cabling complexity by consolidating four SFP+ connections into a single QSFP endpoint, supports low insertion loss for reliable signal transmission over short distances, and simplifies rack-side patching. The fixed 3 m length and black jacket make routing predictable and help maintain tidy cable management in constrained spaces.

Suitable for

• Data center patch panels and spine-leaf switch interconnects
• Uplink aggregation from SFP+ modules to a QSFP port
• Short-reach connectivity between QSFP-enabled switches and multiple servers or switches
• High-density rack installations where port splitting is required

Key specifications

• Form factor: QSFP to 4× SFP+ passive fiber breakout
• Length: 3 meters
• Cable jacket color: black
• Transmission: splits one 40Gb/s link into four 10Gb/s links
• Fiber type: multimode fiber suitable for short-range links
• Connector types: one QSFP plug and four SFP+ plugs (female interfaces on modules/switches)
• Application: short-range, high-density interconnects in racks and data centers

How to use

Insert the QSFP end into the QSFP port of the switch or transceiver and plug the four SFP+ ends into the corresponding SFP+ ports on the target devices or patch panel. Ensure that transceiver types and supported link speeds on both ends are compatible with a 40Gb/s to 4×10Gb/s breakout configuration. Route the 3 m cable to avoid sharp bends and maintain minimum bend radius to reduce attenuation and preserve multimode fiber performance. No external power or configuration is required for passive operation; link negotiation is managed by the connected devices.

Recommendations

Confirm that the network devices support QSFP-to-4×SFP+ passive breakout operation and that SFP+ modules and switch firmware are compatible with a breakout topology. Use in short-range multimode applications as intended; for longer distances or single-mode requirements, choose appropriate active or single-mode solutions. Handle fiber connectors carefully and keep dust caps on unused ends to maintain signal integrity.
