# 100G QSFP28 Active Optical Cable: High-Speed Data Transmission Solution

## Introduction to QSFP28 Active Optical Cables

The 100G QSFP28 Active Optical Cable (AOC) represents a significant advancement in high-speed data transmission technology. Designed for data centers, high-performance computing, and enterprise networking applications, these cables provide a reliable and efficient solution for transmitting data at 100 gigabits per second (Gbps) over optical fiber.

## Key Features of 100G QSFP28 AOC

### High-Speed Performance

100G QSFP28 AOCs support data rates of up to 100Gbps, making them ideal for bandwidth-intensive applications. The QSFP28 form factor ensures compatibility with modern networking equipment while delivering exceptional performance.

### Low Power Consumption

Compared to traditional copper solutions, active optical cables consume significantly less power while maintaining superior signal integrity over longer distances. This energy efficiency makes them particularly attractive for large-scale data center deployments.

### Extended Reach Capabilities

While standard direct attach copper cables are limited to about 5 meters, 100G QSFP28 AOCs can reliably transmit data over distances up to 100 meters (depending on the specific model), eliminating the need for additional signal regeneration equipment.
