When comparing the two methods, it is evident that fusion splicing far outweighs cold cure. Optical fiber transmission has the advantages of wide transmission frequency, large communication capacity, low loss, no electromagnetic interference, small diameter of optical cable, light weight, rich source of raw materials, etc. When light is. The cold cure method, also known as mechanical splicing, involves the combination of anaerobic adhesive and activator. It requires specific connectors to facilitate the curing process, ensuring a secure and durable bond between the fibre optic cables without the need for heat sources or specialised. Fiber cold splicing refers to using special tools to mechanically connect two optical fibers. The advantages are stable quality and small connection loss (about 0.
