Active Optical Cable mainly relies on its built-in photoelectric converters and optical amplifiers to deal with the problem of optical signal attenuation. The following is a detailed explanation of how Active Optical Cable deals with the problem of optical signal attenuation:
First, we need to understand the reasons for optical signal attenuation. When optical signals are transmitted in optical cables, due to various reasons such as material absorption, scattering, fiber bending, connector insertion loss and environmental factors, the optical signal energy will be lost, that is, optical signal attenuation. This attenuation will affect the transmission distance and reception quality of the signal.
Active Optical Cable converts optical signals into electrical signals through built-in photoelectric converters, and then uses electrical signal processing technology to amplify and compensate the signals. Specifically, the optical amplifier in Active Optical Cable will amplify the optical signal to make up for the energy lost during transmission. At the same time, Active Optical Cable may also use some advanced signal processing technologies, such as equalization technology, pre-distortion technology, etc., to further improve the transmission quality of the signal.
In addition to the built-in optical amplifier, Active Optical Cable may also use some other strategies to reduce the attenuation of optical signals. For example, optimizing the manufacturing process of optical fibers, selecting low-attenuation optical fiber materials and connectors, and reasonably designing optical fiber wiring solutions. These measures can reduce the attenuation of optical signals to a certain extent and improve the transmission quality and distance of signals.
It should be noted that although Active Optical Cable can handle the attenuation of optical signals, it is not necessary to use Active Optical Cable in all cases. In some short-distance, low-rate application scenarios, passive optical cables may be sufficient to meet the needs. In addition, Active Optical Cable is more expensive than passive optical cables, and maintenance and management are relatively complex. Therefore, when choosing to use Active Optical Cable, it is necessary to make comprehensive considerations based on specific application scenarios and needs.
In general, Active Optical Cable can effectively handle the attenuation of optical signals and improve the transmission quality and distance of signals through built-in components such as optoelectronic converters and optical amplifiers, and uses technical means such as signal amplification and compensation.
