The 40G QSFP+ to 4×10G SFP+ Active Optical Cable (AOC) is a high-performance breakout solution designed for flexible and efficient bandwidth distribution in modern data center and enterprise networks. It enables a single 40G QSFP+ port to be split into four independent 10G SFP+ connections, supporting scalable network architectures and optimized port utilization.

Built with OM3 multimode fiber and integrated active transceivers, this 5-meter cable delivers low-latency, high-bandwidth transmission with excellent signal integrity. Compared to copper DAC alternatives, the AOC design significantly reduces electromagnetic interference (EMI) and supports longer reach with consistent performance. It is ideal for switch-to-server or switch-to-switch breakout scenarios in high-density networking environments. OEM customization is available for length, labeling, and compatibility coding.

Q1: What is the function of a 40G to 4×10G breakout AOC?
A: It allows a single 40G QSFP+ port to be divided into four independent 10G SFP+ connections, improving port flexibility and utilization.

Q2: How is an AOC different from a DAC cable?
A: AOC uses optical fiber with active transceivers, providing better signal integrity, longer reach, and lower EMI compared to copper DAC cables.

Q3: What does OM3 mean?
A: OM3 is a multimode fiber standard optimized for high-speed short-distance transmission in data center environments.

Q4: Is this compatible with all network equipment?
A: It is compatible with most major vendors, but EEPROM coding may be required for specific switch models.

Q5: What environments is this cable best suited for?
A: It is ideal for data centers, cloud infrastructure, and high-density networking environments requiring flexible 40G to 10G breakout.
