The 100G QSFP28 to 4×SFP28 Active Optical Cable (AOC) is a high-performance optical breakout solution designed for next-generation data center and high-speed networking applications. It enables seamless conversion from a single 100G QSFP28 port to four independent 25G SFP28 ports, providing flexible bandwidth distribution for modern switch-to-server architectures.

Built on OM3 multimode fiber technology, this 3-meter AOC delivers low-latency, high-bandwidth transmission with excellent signal integrity over short-range interconnects. Unlike passive copper DAC cables, the active optical design reduces EMI, improves signal quality, and supports higher port density in high-performance computing (HPC), cloud, and AI workloads. Its plug-and-play QSFP28 and SFP28 connectors simplify deployment while maintaining reliable 100G-to-4×25G breakout functionality. OEM customization options are available for length, labeling, and compatibility tuning.

Q1: What is the purpose of a 100G to 4×25G AOC cable?
A: It allows a single 100G port to be split into four 25G connections, improving port utilization and network flexibility.

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

Q3: Is this compatible with all QSFP28 switches?
A: It is compatible with most major vendors, but firmware and EEPROM coding may be required for specific platforms.

Q4: What does OM3 mean in this cable?
A: OM3 is a multimode fiber standard optimized for high-speed short-distance transmission, commonly used in data centers.

Q5: Can the length be customized?
A: Yes, OEM options include custom lengths, typically ranging from 1m to 30m depending on system requirements.
