CBO BlueOptics QSFP to 4x SFP+ Active Optical Cable 3 m (model 470-ACBS-BL)

The CBO BlueOptics QSFP to 4x SFP+ Active Optical Cable 3 m is an active optical cable (AOC) designed to provide a direct high-speed link between a QSFP port and four SFP+ ports over a 3-metre multimode optical connection. The cable uses integrated transceivers and optical fiber to deliver low-latency, high-bandwidth connectivity while reducing susceptibility to electromagnetic interference. It is intended for short-reach interconnects in data center environments, server uplinks and blade chassis where reliable, compact and low-power optical links are required.

Advantages

This BlueOptics AOC offers simplified cabling by combining a QSFP interface with four SFP+ endpoints in a single assembly, eliminating the need for separate transceivers and patch cords. Optical transmission reduces electrical noise and crosstalk, improving signal integrity in dense rack installations. The active design integrates required electronics for signal conversion and equalization, supporting consistent performance across the 3 m link while keeping power consumption and heat generation lower than many active copper alternatives.

Suitable for

• Data centre switch-to-switch uplinks and spine-leaf interconnects
• Server to top-of-rack switch connections and blade server aggregation
• High-density network deployments requiring QSFP to multiple SFP+ breakout
• Environments needing low-latency, short-reach multimode optical links

Key specifications

• Form factor: QSFP to 4× SFP+ breakout AOC
• Length: 3 metres
• Transmission medium: multimode optical fiber with active transceivers
• Supported interfaces: one QSFP port to four SFP+ ports
• Typical use: short-reach (data centre/server rack) interconnects
• Latency: low, suitable for high-performance networking
• Electromagnetic immunity: optical transmission reduces EMI sensitivity

How to use

Insert the QSFP end into the device QSFP port and connect the four SFP+ ends to the corresponding SFP+ ports on the target device. Ensure both devices support QSFP-to-4xSFP+ breakout functionality and are powered off or configured per vendor guidelines before making connections if recommended. After insertion, verify link status through device LEDs or management interfaces and confirm correct lane mapping and speed settings in the switch or server configuration.

Usage recommendations

For optimal performance, route the 3 m cable to avoid tight bends and maintain the manufacturer’s minimum bend radius. Use in rack and chassis layouts that support multimode short-reach optics and verify compatibility with the host hardware’s breakout and firmware requirements prior to deployment.
