Buy fiber optic cable

Price: 2.00 yuan Procurement Quantity: 1 Packaging: Product specifications: GYTA GTAS Material: qualification: 
 4-96 core long-term acquisition of a large number of fiber optic cable, the model limited to unlimited, the brand, produced after 2008. Light and its characteristics: 

 (1) light is an electromagnetic wave 

 The visible part of the wavelength range: 390 ~ 760nm (nm). Greater than 760nm part of the infrared light is less than 390nm is ultraviolet. Fiber applications: 850,1310,1550 three kinds. 

 (2) light refraction, reflection and total reflection. 

 Due to the propagation velocity of light in different substances are different, so the light fired from a substance to another substance, refraction and reflection at the interface of two substances. Moreover, the angle of refraction of light with the incident light angle changes. When the incident light angle to reach or exceed a certain angle, the refracted light will disappear, the incident light be reflected back, which is the total reflection of light. Different substances on the same wavelength of light refraction angle is different (ie different substances have different optical refractive index), the same material is also different for different wavelengths of light refraction angle. Optical fiber communication is based on the above principle formed. Letter
