Optical fiber is finally adopted to the countryside, underneath let’s check the basic knowledge of optical fiber, here we go:

First of all, what is optical fiber?

Optical fiber is the abbreviation of optical wave guide fiber, is a kind of fiber made of glass or plastic, can be used as light transmission tool. Transmission principle is light’s total reflection.

Second, what are the types of optical fiber, here below are the main types: Silica Fiber takes Silica (SiO2) as the main raw material, and mixing by the different doping amount, to control the distribution of refractive index of fiber core and optical fiber cladding. Quartz fiber (glass) series, has the characteristics of low consumption, broadband, has been widely used in cable television and communications systems.

Plastic Clad Fiber is made of high purity quartz glass fiber core, and the refractive index was slightly lower than quartz, say plastics such as silica gel as a step Fiber cladding. Compared with quartz optical fiber, its fiber core is much thicker, the characteristics of high numerical aperture (NA). Therefore, it can be integrated with LED ( light-emitting diode ) much easier, and the loss is small. So, it is very suitable for the local area network (LAN) and NFC.

This is the fiber core and cladding are in plastic optical fiber (polymer).Products are mainly used for decoration and light illumination and early close light in the optical communication. Raw materials are mainly organic glass (PMMA), polystyrene (PVC (PS) and polycarbonate (PC).Loss is restricted by plastic inherent C-H combined structure, general it reaches dozens of dB per km. In order to reduce loss, we are developing application of fluorine series plastic. Due to the Plastic Optical fiber (Plastic Optical fiber) of the fiber core is 1000 microns in diameter, 100 times larger than the single mode quartz Optical fiber, it is simple, bendable and easier to fit up. In recent years, along with the progress of broadband as a graded-index (GI), the development of the refractive index of the multimode plastic optical fiber has becoming attractive. Recently, in car internal LAN applications, it develops very fast, furthermore it may also be applied in the family LAN in the future.

Finally, what are the advantages of optical fiber?

Optical fiber is transmitted by light, and light is electromagnetic waves, transmitted through reflection, which makes optical fiber have the characteristics of the reflected light, it can be as little as possible to reduce losses, or even no loss, high fidelity. At the same time, the optical fiber is very thin, and the proportion of glass or plastic (polymer) is small, so it’s very light, easy to transport, installation is convenient (plastic optical fiber);And optical fiber transmission light, non-conductive, not affected by electromagnetic field effect, in which the transmission of the optical signal is not affected by electromagnetic field, so the optical fiber transmission has a strong ability to resist the electromagnetic interference and industrial interference,  it also has reliable working performance, cost down under the development of plastic optical fiber , which makes the public enjoy the high speed fiber network with low cost.

Society is always stepping forward, fiber era is approaching day after day, fiber optic router, optical switches, optical module and so on, these are not insubstantial high-tech products, they will be like ordinary citizens, has become common, ordinary. Guangdong IPT Industrial Co.,LTD, will continue to uphold the tenet of the company, in the optical fiber industry to make better products, services to the public!
