We often see optical cable in our daily life, so what is the optical cable for?
First, what is the cable used for
Its main role is optical signal transmission, can meet the optical, mechanical and environmental performance specifications, usually placed in the sheath of one or more optical fibers, can be made of communication cable components alone or in groups. It is a kind of communication road made of optical fiber, plastic sheath and plastic outer layer for optical signal transmission.
Second, how to buy optical cable
1, from the skin, the normal high-quality cable skin is made of polyvinyl chloride material, looks smooth and shiny, and excellent flexibility, and there is a flame retardant effect, if its outer gloss is poor, and will be connected to the inferior coat, it is inferior, this kind of cable material is poor, the use of a long time will also appear cracking water seepage problem, very dangerous.
2, from the perspective of optical fiber, the fiber of the high-quality optical cable is usually a grade A core, while the poor quality is c, d, which will lead to the transmission distance is too short, there is no way to connect with the pigtail.
3, the purchase of optical cable to ensure that the steel wire meets the standard, the normal steel wire should be through special treatment, so as to reduce the probability of rust and improve its strength, and the steel wire of inferior optical fiber are latte wire or aluminum wire replacement, insufficient strength, easy to touch will bend, a long time will rust and break.
4, the purchase of optical cable should pay special attention to steel, high-quality optical cable steel strip material is excellent, and both sides have done anti-rust measures, and inferior optical cable usually uses ordinary iron, it is easy to rust damage.
The above is some information about optical cable, from the above article we can see that its main role is to transmit optical signals when we usually buy optical cables, we should also consider from all aspects such as skin, fiber, internal reinforcement wire, etc., so as to ensure such excellent, avoid a lot of problems, I hope to help you.
