Fiber optic cable has developed into a standard component in global communications infrastructure. It is immune to electromagnetic interference and radio frequency interference which makes it one of the best cable mediums. Optical fiber has the ability to transport signals over long distances which is why it is used in most networks. In its simplest form optical fiber is essentially a thin glass strand which is used to transmit a pulse of light. As the light travels it is contained in the glass by cladding. Multiple strands are bundled together within a jacket which is what forms the resulting cable. While each kind of secondary coating line is essentially the same, you will find unique differences which has to be considered when deciding what type is best for a specific application.
One thing to consider is whether or not single mode or multi-mode optical fibers are required. Multi-mode fiber allows the signal to travel along multiple pathways inside of the glass strand. Single mode fiber requires laser technology for sending and receiving data. This provides it the ability to carry a single signal four miles which is why it is usually utilized by telephoning cable-television providers. One thing to keep in mind is that the electronic infrastructure required to manage single mode transmissions are considerably more expensive than multi-mode which is why multi-mode is usually the smart choice for geographic area networks.
The next thing to take into consideration is if loose tube or tight buffered optical fiber is the greatest solution. Loose tube designs include the glass core and clouding having a thin protective acrylic coating. This is considered to be the most basic usable form for installation purposes. Loose tube optical fibers are typically preferred when high strain counts are needed together with larger protective jackets. Some newer designs for indoor fiber are now using loose to constructions too. Overall, tight buffered continues to be more popular option if the fiber-optic cables will be installed in a building. It is because the protective jacket is directly over the fiber strand which makes it easy to work with and eliminates the necessity of a breakout kit.
The last consideration when choosing secondary coating line needs to be the kind of connectors that might be used. You will find 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 referred to as the bayonet style and they are pushed in and twisted to lock the cable in place.
Because the inception of lightwave optical communication with fiber, the main objective has become on the technology for too long-distance telecommunication applications. And that is why single mode glass optical fiber has become the most preferred channels for such applications. As a result of ever-increasing requirement for more bandwidth, the data communication market xttaes risen towards the forefront in fiber optic communication. After several rounds of competition with other technologies, Ethernet is actually the winner for LAN networks.
Silica-based multimode fiber is adopted to supply an affordable optical link with a combination of transceivers based on Vertical Cavity Surface-Emitting Laser (VCSELs). However it is far from the very best solution to distribute such secondary coating line even during premises and home networks or interconnections. Why? Plastic optical fiber (POF), with its its large core, continues to be expected to function as the office and home network media. Plastic optical fiber’s large core allows the use of cheap injection-molded plastic connectors which can significantly lower the complete link cost.
But POF features its own problems. The most significant obstacle is plastic fiber’s high signal loss (attenuation). PMMA has been utilized because the light guiding core for commercially available step-index POF and PMMA’s attenuation is approximately 100 dB/km. This high attenuation significantly limits POF’s applications in data communication applications of over 100m.
