How to distinguish cable types: Multimode fiber: The center glass core is thicker (50 or 62.5μm), and can transmit light in multiple modes. However, its inter-mode dispersion is large, which limits the frequency of transmitting digital signals, and it will become more serious with increasing distance. For example: 600MB / KM fiber has only 300MB bandwidth at 2KM. Therefore, the transmission distance of multi-mode fiber is relatively short, generally only a few kilometers.
Single-mode fiber in communication optical cables : The center glass core is relatively thin (core diameter is generally 9 or 10 μm), and can only transmit light in one mode. In fact, it is a kind of step-type optical fiber, but the core diameter is very small. In theory, only the direct light of a single propagation path is allowed to enter the fiber and propagate straight in the core. The fiber pulse is barely stretched. Therefore, its inter-mode dispersion is small and suitable for remote communication, but its chromatic dispersion plays a major role. In this way, single-mode fiber has higher requirements on the spectral width and stability of the light source, that is, the spectral width is narrow and the stability is good. .
In the face of competition in the communications fiber optic cable recycling market, it is not a mistake to reduce all the recovered fiber cables into the project. We should face the market correctly, find more and tap some potential customer resources, so as to strengthen ourselves, so that some of the remaining optical cables in the project can be sold at a good price. This is a more practical issue. However, some recyclers in our market encounter market downturns and often take measures to reduce the recycling price and make up for their losses. This puts a lot of pressure on our customers. A win-win situation is our main concept of development. It is our wish that the remaining fiber optic cable owners can find some end customers. Letting used fiber optic cables have a good development direction is our main work in the future.
Another major feature of telecommunication cable recycling is to change market pressures by relying on our actual actions. We can't wait for a batch of supplies and orders. We must rely on us to run and act more, and to contact some customers who often use fiber optic cables. Let everyone feel our sincerity, so that more people can trust us, this is the key to the matter. Our company is better at this point. In each issue, we will communicate with customers and discuss the technical experience of the optical cable in the construction unit. Fully integrate with you so that everyone can understand our company. We can also understand the demands of the masses on us, so as to improve and improve our shortcomings in the process of fiber optic cable recycling. This is our business philosophy.
