Fiber optic cable has developed into a standard component in global communications infrastructure. It is immune to electromagnetic interference and radio frequency interference that makes it among the best cable mediums. Optical fiber has the ability to transport signals over long distances which is why it is utilized in most networks. In its most basic form Fiber drawing machine is essentially a thin glass strand that is utilized to transmit a pulse of light. As the light travels it contained within the glass by cladding. Multiple strands are bundled together inside of a jacket that is what forms the resulting cable. While each type of optical fiber is essentially the same, you can find unique differences which has to be considered when deciding which one is right for a particular application.
The first thing to consider is whether or not single mode or multi-mode optical fibers are needed. Multi-mode fiber allows the signal traveling along multiple pathways inside of the glass strand. Single mode fiber requires laser technology for sending and receiving data. This gives it the opportunity to carry a single signal four miles which explains why it is usually used by telephoning cable-television providers. One important thing to be aware of is the fact that electronic infrastructure required to manage single mode transmissions are far more expensive than multi-mode which is why multi-mode is truly the best option for local area networks.
The second thing to take into consideration is whether loose tube or tight buffered optical fiber is the ideal solution. Loose tube designs contain the glass core and clouding having a thin protective acrylic coating. This is considered to be the standard usable form for installation purposes. Loose tube optical fibers are typically preferred when high strain counts are needed in conjunction with larger protective jackets. Some newer designs for indoor fiber now use loose to constructions also. Overall, tight buffered remains the popular option if the fiber-optic cables is going to be installed in a building. This is because the protective jacket is directly within the fiber strand making it easy to do business with and eliminates the need of a breakout kit.
The ultimate consideration when selecting FTTH cable production line needs to be the form of connectors that will be used. You will find a fairly multitude of different connector styles on the market however most distributors only accommodate SC and ST style connectors. SC connectors push in then click when seated. ST connectors are also called the bayonet style and are pushed in and twisted to lock the cable into place.
Because the inception of lightwave optical communication with fiber, the focus continues to be on the technology for long-distance telecommunication applications. And that is certainly why single mode glass optical fiber has become the most preferred channels for such applications. As a result of ever-increasing need for more bandwidth, the data communication market has risen to the forefront in fiber optic communication. After several rounds of competition with other technologies, Ethernet is undoubtedly the winner for LAN networks.
Silica-based multimode fiber is adopted to provide an affordable optical link with a combination of transceivers according to Vertical Cavity Surface-Emitting Laser (VCSELs). However it is really not the most effective solution to distribute this type of silica-based optical fiber even just in premises and home networks or interconnections. Why? Plastic optical fiber (POF), featuring its drvunx large core, has been supposed to be the office and home network media. Plastic optical fiber’s large core allows the use of cheap injection-molded plastic connectors which could significantly lower the complete link cost.
But POF possesses its own problems. The most significant obstacle is Sheathing line. PMMA has been used because the light guiding core for commercially available step-index POF and PMMA’s attenuation is all about 100 dB/km. This high attenuation significantly limits POF’s applications in data communication applications of over 100m.
