FAQ
1. What is active optical cable ?
A: An Active Optical Cable (AOC) is a high-speed data transmission cable that integrates optical fiber technology with electrical components to enable the transfer of data signals over extended distances. It is frequently utilized in applications like data centers, high-performance computing, and networking systems.
2. What is the difference between active and passive cables?
A: In summary, while both active and passive cables serve the purpose of transmitting signals, active cables incorporate built-in electronic components to actively manage and enhance the signal, while passive cables rely solely on the inherent properties of the conductive material for signal transmission.
3. What is the maximum length of active optical cable ?
A: The maximum length of an active optical cable can vary depending on factors such as the cable quality, data rate, and the specific technology used. However, active optical cables have the potential to reach significantly longer transmission distances compared to passive cables. In some cases, active optical cables can achieve transmission distances of up to several hundred meters or even kilometers, depending on the technology and application. It's important to note that the specific maximum length will depend on the product specifications provided by the manufacturer of the active optical cable.
