Fiber optic cable has become a standard component in global communications infrastructure. It is resistant 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 simplest form optical fiber is essentially a thin glass strand which is often used to transmit a pulse of light. As the light travels it is contained in the glass by cladding. Multiple strands are bundled together inside of a jacket that is what forms the resulting cable. While each kind of FTTH cable production line is essentially the same, there are unique differences which should be considered when deciding which one is best for a particular application.
The first thing to consider is if single mode or multi-mode optical fibers are essential. 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 offers it the ability to possess a single signal four miles which is the reason it is usually employed by telephoning cable-television providers. One thing to keep in mind is the fact that electronic infrastructure required to manage single mode transmissions are considerably more expensive than multi-mode which is why multi-mode is often the smart choice for geographic area networks.
The second thing to take into consideration is if loose tube or tight buffered optical fiber is the ideal solution. Loose tube designs include the glass core and clouding having a thin protective acrylic coating. This is regarded as the most basic usable form for installation purposes. Loose tube optical fibers are generally preferred when high strain counts are required in conjunction with larger protective jackets. Some newer designs for indoor fiber now use loose to constructions as well. Overall, tight buffered remains the popular option when the fiber-optic cables will be installed in a building. The reason being the protective jacket is directly within the fiber strand which makes it easy to work with and eliminates the necessity of a breakout kit.
The final consideration when choosing Sheathing line needs to be the type of connectors that might be used. There are a fairly large number 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 they are pushed in and twisted to lock the cable into position.
Because the inception of lightwave optical communication with fiber, the main focus has been on the technology for too long-distance telecommunication applications. And that is why single mode glass optical fiber has been the most preferred channels for such applications. As a result of ever-increasing need for more bandwidth, the data communication market xttaes risen for the forefront in fiber optic communication. After several rounds of competition along with other technologies, Ethernet is actually the winner for LAN networks.
Silica-based multimode fiber is adopted to offer a cheap optical link with a combination of transceivers based on Vertical Cavity Surface-Emitting Laser (VCSELs). However it is really not the best answer to distribute such secondary coating line even in premises and home networks or interconnections. Why? Plastic optical fiber (POF), using its its large core, has become supposed to become the office and home network media. Plastic optical fiber’s large core allows the usage of cheap injection-molded plastic connectors which may significantly lower the complete link cost.
But POF possesses its own problems. The most significant obstacle is plastic fiber’s high signal loss (attenuation). PMMA has been utilized since 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 in excess of 100m.
