Abstract
An optical fiber replacement method in an optical network is provided. The optical fiber replacement method in the optical network is based on blocking due to an optical signal noise ratio limitation, in which standard single-mode optical fibers in an existing optical network are gradually replaced with ultra-low loss optical fibers. With the optical replacement method in the optical network, performance of the optical network can be improved to the greatest extent while ensuring low replacement cost in a process of gradually replacing the optical fibers.
