Various industries, such as communications technology, navigation, and medicine, as well as the oil and gas industry and space, widely use fiber optics to transmit large amounts of data over long distances. The quality of the transmitted signal depends on how accurately and reliably the ends of the quartz fibers are connected to the ends. Scientists from the Perm National Research Polytechnic University (PNIPU) have developed a new method for connecting optical fibers using a hydrogel made of fused silica and alkali. This technology allows for more reliable connection of fiber lines and improves light signal transmission.
Optical connectors play an important role in the integration of fiber optic systems. It allows you to quickly connect and disconnect fiber lines to each other and to various devices. The effectiveness of the connection depends on the method of insertion of the fiber end; because any gap may lead to signal loss and errors in data transmission.
The main material for the production of tips is fused quartz, which provides high resistance to both chemical and mechanical effects. When working with optical fiber at high temperatures up to 300°C, the use of polymer adhesives becomes impossible, while fused silica remains a reliable material. Laser welding is also used to join quartz parts, but this technique has limitations in mass production due to the difficulty of ensuring a completely leak-proof joint.
Taking these factors into account, scientists developed a hydrogel that has proven effective in bonding optical fibers. It creates the strong connection required for stable data transmission through the chemical reaction between the alkali and fused silica surface. This approach allows us to safely conduct research and development in the field of fiber optic technologies, ensuring high reliability and efficiency in information transfer.
