Why Choose Fiber Optic Internet
on Thursday, 14 February 2013. Posted in Company News
The three pillars of the modern communication network is : fiber-optic communications, satellite communications and radio communications, and fiber optic communications is the main, this is because the optical fiber communication has many outstanding advantages:
1.A frequency band, a large capacity communication.
The fiber available bandwidth of about 50000 GHz,1.7Gb / s optical fiber communication systems which put into use in 1987,a pair of optical fibers can transmit 24192 telephone, 2.4Gb / s system.Simultaneous transmission of more than 30,000 road phone.
2. Low loss, long distance relay.
Current utility quartz fiber loss can be less than 0.2dB/km, are lower than the loss of any other transmission medium, if the future use of the non-silica-based very low loss optical fiber, the theoretical analysis of the loss can be decreased to 10-9dB/km
3. Anti-electromagnetic interference.
Optical fiber is an insulator material, it will not be interferenced by natural lightning , ionosphere changes in sunspot activity , not be interferenced by the electrified railway feed wire and high-voltage equipment and industrial electrical interferenced, can also use it in parallel with the high voltage transmission lines erected orconstitute a composite cable with the power conductor composite.
4. no crosstalk, and confidentiality.
Lightwave transmission in the cable, it is difficult from the fiber leaking out, even in a turn at the bend, radius is very small, the leakage of the lightwave also very weak,the effect will be better if the surface of the fiber or cable coated with a layer of matting agent , so that,even if the total number of fiber optic cable within a lot can also be achieved without the crosstalk interference outside of the cable, but also unable to eavesdrop on the information of the optical fiber transmission.
5.Fiber diameter thin, light weight, soft.
Fiber core diameter is very thin, about 0.1mm, it is only one percent of the single tube of the coaxial cable; the diameter of the cable is also small, 8-core optical fiber cable of a cross-sectional diameter of approximately 10mm, whereas the standard coaxial cable is 47mm
6. Fiber rich raw material resources, saving metal fiber material.
Fiber material quartz (the gasification silicon), Earth inexhaustible supply of raw materials ., the main material of the cable is copper, the world's reserves of copper is not much, and replaced by optical fiber cables, you can save a lot of metal material, with a rational use of resources of the earth significance.The other advantages of fiber optic:also has strong corrosion resistance, anti-nuclear radiation, energy consumption and small.
In recent years, the development of optical fiber communications quickly, it has profoundly changed the face of the telecommunications network, to become the most solid foundation of the modern information society, and to show us infinitely better future.
