Introduction
As data center transmission rates gradually approach 800G and 1.6T, the losses of passive direct-attach copper (DAC) cables increase, and the interconnection lengths fail to meet the corresponding demands. To address the cost issue of extending short-distance device interconnections, the ACC Active Copper Cable and AEC Active Cable have emerged. High-speed cable products expand the market with their cost-effectiveness, high-speed rates, and low losses, providing cost-effective wiring solutions. They can be primarily applied in data centers, high-performance computing (HPC), industrial automation, and other fields. This article will explore what ACC Active Copper Cable is and its advantages.
What is ACC Active Copper Cable?
ACC (Active Copper Cable) is an active copper cable that uses chips to compensate for the high-frequency losses of passive copper DACs, functioning more like an active cable that amplifies the simulated signal. It extends the transmission distance of traditional copper cables to a wider range of applications. ACC can also be used to connect TOR and servers. It provides a cost-effective solution for short links, thus offering greater bandwidth transmission. The transmission distance of ACC can exceed 3m in high-speed transmission, making it crucial to select the correct cable length as it may be a key variable in overall performance.
Wire Gauge
AWG
Since DAC is composed of shielded twisted copper wire, there are different specifications of wires according to the cable requirements. The AWG value is a function of the wire thickness (in inches) and represents the cable diameter, ranging from 24 to 30 AWG.
As a general rule of thumb, the number in front of AWG (e.g., 24 AWG, 26 AWG) indicates the number of holes the wire must pass through before forming the final diameter; the larger the number, the higher the grade of the wire passing through the holes, resulting in a smaller wire diameter and a lower current capacity.

Transmission Distance
TRANSMISSION DISTANCES
DAC is mainly used for interconnections within and between cabinets. The transmission distance of DAC is limited by factors such as material and connector high-frequency losses, with copper DACs supporting transmission rates of 10G/25G reaching a maximum of 7 meters, while those for 40G/100G can reach a maximum of 5 meters. If the distance between devices exceeds these limits, a more expensive AOC active optical cable and optical module link solution must be used. At transmission rates of 800G and 1.6T, the advantages of ACC active cables become apparent for solving the cost issue of extending short-distance device interconnections.

Transmission Rates and Packaging Types
TRANSMISSION RATE & FORM
ACC Active Copper Cable supports transmission rates and packaging types including 10G SFP+, 25G SFP28, 40G QSFP+, 50G QSFP+, 100G QSFP28, 200G QSFP-DD, 400G OSFP, 800G OSFP, 400G QSFP DD, and 800G QSFP-DD.
Tips: DAC direct-attach cables come in both passive and active types, with active copper cables having a longer maximum transmission distance than passive ones, while AOCs are all active.
Core Advantages
CORE COMPETITIVENESS
The core advantages of ACC active copper cables include: long application distances, plug-and-play capabilities, protocol transparency, minimal impact from temperature changes, lower costs, and reduced power consumption. These features meet the urgent needs for energy savings and cost control in large data centers, aligning perfectly with the growing emphasis on green energy efficiency and cost control in large data centers. They are suitable for fiber optic cable solutions in 800G data centers.
