[Knowledge] How is a fiber optic network built?
Traditional communication networks are based on simulated data and implemented with copper cables. However, with the rapid progress of technology, the transmission rate of the network must be increased accordingly. Today, copper cables are gradually being replaced by modern optical fibers.How has fi

[Knowledge] How to solve the loss problem when fiber is fused?
When light is transmitted in the optical fiber, loss will occur, and the optical fiber loss is mainly composed of the transmission loss of the optical fiber itself and the fusion loss at the optical fiber fusion splice. Let us first understand the main factors that affect the loss of optical fiber f
