INSIDE THE FIBER OPTIC

Inside The Fiber Optic

Now Inside The Computers will discuss about Inside the Fiber Optic, and we will go inside the fiber optic technology.

Fiber optic media has more benefit and advantage in the performance and the reliability when transferring data. This media make data communicating easy and fast to do. So, this media become favorite media for many users to have the high quality communication. This media not only capable to do a communicate between building and building, block to block, city to city, but this media also already been trusted to connect between continent and continent, island to island, country to country, nation and nation in this world. Fiber optic also has been trusted for long time to become main communication media (backbone) from the internet all over the world. To connect the network in one country with another country or continent to other continent, fiber optic already participates for long time in the world of communication. That’s why this media become one of trusted media because the performance, quality, and reliability. And now we will see inside this media one by one, even not too detail but I think that will be enough to show how good this technology.

The Characteristics of Fiber Optic Communication

 Fiber optic communication technology has many type and characteristics. From this type and characteristics finally they made a lot of connector type, cable, and variation tools. All of this type and characteristics differences resulting the different way of work (performance). Fiber optic communication technology is divide become few type by two factor, which is structural factor and property factor from the transmission system. This two factor who make the quality different and also the different of price for the global line. Structural factor more focus on the physically media which is fiber optic. And property factor on transmission system more focus on the lights of data is treat in the media. The modifying from the two factors will make the fiber optic technology become more vary. Base on structure factor and property factor on transmission system, the fiber optic technology dividing become two categories, which is:

Single Mode Fiber Optic

If we seen from the factor of system transmission property, single mode is a data transmission system which is tangible of light of radiance, where the inside of it has one light index without bouncing and spread as long that landscape media. One light or radiance which doesn’t bounce inside that optic media make the fiber optic technology has a little problem. But the problems comes from the outside factor and only a physically problems. Single mode can be seen from the structural form which is constitute of fiber optic technology who work using the main (core) fiber with very small diameter, about 8 until 10 micrometer. With the size of fiber core which is very small, the light that can pass it is only one light mode which is the light with phase length about 1310 or 1550 nanometer. Single mode can carry data with bigger bandwidth than multi mode fiber optics, but this technology need light source with thin spectral and that mean is very expensive system. Single mode can carry data faster and 50 times more far then multi mode. But you also have to spend more money to use it.

Multi Mode Fiber Optic

Fit with the names, this technology has many advantage and also disadvantage which cause by amount of light signal inside of fiber optic media. The light inside must be more than one. If we see from the transmission system property factors, multi mode fiber optic is data transmission technology through an optic with using few light indexes inside of it. The light wills bouncing until that light reach to the destination.

The light signal in multi mode fiber optic technology can be produce until 100 light modes. If we seen from structural factor, multi mode technology is fiber optic technology which using bigger size of core compare with single mode. The size of multi mode cable generally is between 50 until 100 micrometer. Usually the NA size inside multi mode cable is between 0.20 until 0.29. With bigger size and higher NA, then fiber optic multi mode technology created.

The advantage of this bigger core and higher NA is, first, information ray will be more flexible to move inside the fiber optic cable. Because of that size, users are easily to connect core to core if we need to connect it. When connecting or we use to call splicing, the accuracy and precision between the cores we want to connect become uncritical thing for the data light.

Another advantage from this technology is making you possible to use LED as the light source, compare with single mode which have to use laser as the light source. What we have to know, LED is a cheap component so the equipment component as the light source also inexpensive. LED is not too complex in take care and using the LED, also has good reliability comparing with laser. So this technology has significant different from the price factor compare with single mode.

But, this technology also brings uncomfortable to the users. When the amount of this mode increase, the affect from dispersion aspect also increasing. Dispersion aspect (intermodal dispersion) is an affect where the lights mode with a lot of amount will arrived in the end of receiver with unsynchronized time. The times delay (different) is causing the light pulse becoming spread in acceptance. The influence is, the bandwidth result can’t increase, so the communication limited on the bandwidth. The producer of fiber optic cable is modifying the cable, so the maximum bandwidth can be reach.
