Active Optical Cable (AOC) Wholesale

There are significant differences between active optical cables (AOCs) and passive optical cables in terms of structure and function. AOCs use optical fiber for connection, and although it accepts the same electrical input as standard copper cables, it greatly enhances the transmission speed and range of the signal by performing electrical-optical conversion at both ends of the connection. This enables AOCs to maintain high-quality signal transmission over long distances, making them suitable for scenarios that require high performance and long-distance transmission.

In contrast, passive optical cables are pure signal conduits and do not contain any electronic components for signal enhancement, so signal attenuation and quality degradation may occur over long distances.

Direct Attach Copper Cables (DACs) are made of copper cables and are available in two types: passive and active. Passive DACs do not require signal conditioning, so they have low power consumption and low production costs, making them ideal for short-distance applications, typically up to 10 meters in length. Active DACs have built-in electronics to boost the signal, allowing for slightly longer distances, up to 15 meters.

In contrast, Active Optical Cables (AOCs) are made of multimode fiber and convert electrical signals to optical signals with the need for external power, making them suitable for transmissions up to 100 meters, and even 300 meters with pure fiber, with transmission rates up to 48G. Although AOCs are generally more expensive than DACs, they have a clear advantage in eliminating electromagnetic interference (EMI) because optical fiber is not affected by EMI. DACs are an economical choice for short-distance, low-power connections, while AOCs are a more ideal choice when long-distance, high-speed transmission and EMI protection are required.

MPO fiber patch cords and AOC fiber patch cords are significantly different in their uses and structures. MPO fiber patch cords utilize multi-core design and MPO connectors, and are designed for high-density fiber networks, greatly improving the efficiency and density of wiring in data centers, high-performance computing, and telecommunication networks. They support high-speed data transmission and can be deployed quickly.

AOC fiber patch cords combine the advantages of optoelectronic conversion and optical fiber, and achieve long-distance, high-speed data transmission between two terminals through built-in optoelectronic conversion chips. With its low power consumption, lightness, and strong anti-interference ability, AOC is particularly suitable for internal connections in data centers, high-performance computing, and transmission needs between ultra-high-definition display devices. AOC is seen as a highly promising option, while MPO continues to play a key role in high-density application environments.

AOC HDMI cable (Active Optical Cable HDMI) uses optical fiber technology to transmit data. Compared with traditional copper cable HDMI, it can maintain the integrity of high-resolution signals over longer distances, usually up to 100 meters or up to 300 meters in the case of pure optical transmission without signal attenuation. This cable supports high-bandwidth and high-speed data transmission with a bandwidth of up to 48Gbps, suitable for video and audio transmission with 4K@144Hz and 8K@60Hz resolutions. It also has a lighter and more flexible design and is easy to install. Due to the transmission of optical signals, AOC HDMI cables are immune to electromagnetic interference (EMI) and provide stable and reliable signal quality. They are particularly suitable for use in occasions that require high-quality long-distance transmission, such as large home theaters, commercial displays, outdoor activities, or digital signage.

Active Optical USB Cable transmits USB signals through optical fiber technology, which can achieve high-speed data transmission up to 100 meters over distances exceeding traditional copper cables without affecting signal quality. The optical fiber material makes it lightweight, flexible, easy to install, and has the advantage of anti-electromagnetic interference, ensuring signal stability in multi-device environments. These cables may require additional power support, usually provided through the USB connection or external power supply. USB optical fiber cables are very suitable for industrial environments or situations where long-distance high-speed data transmission is required to ensure data integrity and transmission speed.
