Abstract
In the 21st century, following the continuous progress of science and technology, in order to satisfy the development of 5G mobile communication to
high speed, low latency and large capacity, Starting from optical fiber performance and manufacturing technology, Comparative analysis of traditional
communication optical fibers, 5G Novelty Fibers under different application fields is explored, which points out the research direction for the new fiber
for 5G applications in the future.
