Fiber optic cable has turned into a standard component in global communications infrastructure. It is immune to electromagnetic interference and radio frequency interference which makes it among 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 inside of a jacket which is what forms the resulting cable. While each type of Fiber drawing machine is essentially the same, there are unique differences which must be considered when deciding what type is the best for a certain application.
The first 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 within 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 often employed by telephoning cable-television providers. One thing to keep in mind is that the electronic infrastructure needed to manage single mode transmissions are considerably more expensive than multi-mode which explains why multi-mode is usually the smart choice for neighborhood networks.
The next thing to consider is whether loose tube or tight buffered optical fiber is the best solution. Loose tube designs consist of 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 essential along with larger protective jackets. Some newer designs for indoor fiber now use loose to constructions as well. Overall, tight buffered is still the more popular option once the fiber-optic cables will be installed in a building. The reason being the protective jacket is directly on the fiber strand making it easy to work with and eliminates the need of a breakout kit.
The final consideration when choosing secondary coating line needs to be the form of connectors that might be used. You can 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 called the bayonet style and they are pushed in and twisted to lock the cable into position.
Considering that the inception of lightwave optical communication with fiber, the focus has become 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. Due to the ever-increasing necessity for more bandwidth, the info communication market xttaes risen for the forefront in fiber optic communication. After several rounds of competition with some other technologies, Ethernet is obviously the winner for LAN networks.
Silica-based multimode fiber is adopted to supply an inexpensive optical link with a combination of transceivers based upon Vertical Cavity Surface-Emitting Laser (VCSELs). However it is far from the best means to fix distribute such Sheathing line even during premises and home networks or interconnections. Why? Plastic optical fiber (POF), with its its large core, has been expected to function as the office and home network media. Plastic optical fiber’s large core allows using cheap injection-molded plastic connectors which could significantly lower the complete link cost.
But POF possesses its own problems. The most important 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 about 100 dB/km. This high attenuation significantly limits POF’s applications in data communication applications of over 100m.
