Optical transport refers to the use of optical technology for transmitting data over long distances in telecommunications networks. This technology utilizes light signals to carry data through optical fibers, allowing for high-speed and high-capacity communication. Optical transport networks are widely used in modern telecommunications systems, including internet service providers, mobile networks, and data centers. These networks provide fast and reliable transmission of data, making them essential for supporting the increasing demand for high-speed internet and other digital services. Research in optical transport focuses on improving the performance, efficiency, and reliability of these networks, as well as exploring new technologies and solutions to meet the growing demands of our digital world.
