As a key technology for high-speed data transmission, Active Optical Cable breaks through its transmission rate bottleneck to achieve higher performance, which is the focus of current research.
From the perspective of technical principles, improving the performance of optical transmitting and receiving modules is one of the keys. More advanced optical transmitting chips can be developed to increase their modulation rate. For example, the use of new modulation formats, such as high-order modulation technology, can carry more data information at the same optical wavelength, thereby increasing the transmission rate. At the same time, the sensitivity and bandwidth of the optical receiving module are optimized so that it can receive and demodulate signals more accurately and quickly. This requires breakthroughs in materials science and semiconductor technology to produce optoelectronic components with better performance.
The performance optimization of the optical fiber itself is also crucial. Research new optical fiber materials and structures to reduce the dispersion and loss of optical fibers. For example, the use of low-loss special optical fibers can reduce the energy attenuation of optical signals during transmission, so that optical signals can maintain higher quality over longer distances. At the same time, by improving the structural design such as the refractive index distribution of the optical fiber, the influence of dispersion on the signal can be effectively reduced, the integrity of the signal can be ensured, and conditions for high-speed transmission can be created.
Innovation in multiplexing technology is also an effective way to increase transmission rates. Wavelength division multiplexing technology can be further expanded to increase the number of multiplexed wavelengths, transmit more optical signals of different wavelengths simultaneously in the same Active Optical Cable, and realize parallel transmission of multiple data channels. In addition, the comprehensive use of technologies such as time division multiplexing and space division multiplexing can fully tap the transmission potential of Active Optical Cable.
At the system level, the overall link design of Active Optical Cable needs to be better optimized. Reduce signal loss and reflection in connectors, adapters and other links to ensure efficient and stable signal transmission channels from the source to the destination. At the same time, use advanced signal processing algorithms and error correction technologies to compensate and repair signal damage during transmission to improve transmission reliability and rate. Through the collaboration of these multi-dimensional methods, it is expected to break through the existing bottleneck of Active Optical Cable transmission rate.
