Fiber optic cable has turned 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 capacity to transport signals over long distances which is why it is used in most networks. In its simplest form FTTH cable production line 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 will find unique differences which must be considered when deciding which one is the best for a particular application.
One 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 within the glass strand. Single mode fiber requires laser technology for sending and receiving data. This offers it the cabability to have a single signal four miles which is why it is usually employed by telephoning cable-television providers. One important thing to bear in mind would be that the electronic infrastructure required to manage single mode transmissions are far more expensive than multi-mode which explains why multi-mode is usually the best option for neighborhood networks.
The second thing to take into consideration is if loose tube or tight buffered optical fiber is the greatest solution. Loose tube designs contain the glass core and clouding having a thin protective acrylic coating. This is recognized as the most basic usable form for installation purposes. Loose tube optical fibers are generally preferred when high strain counts are needed along with larger protective jackets. Some newer designs for indoor fiber now use loose to constructions too. Overall, tight buffered remains the popular option when the fiber-optic cables is going to be installed in a building. The reason being the protective jacket is directly on the fiber strand that makes it easy to work with and eliminates the need of a breakout kit.
The last consideration in choosing SZ stranding line ought to be the kind of connectors which will 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 known as the bayonet style and therefore are pushed in and twisted to lock the cable into place.
Considering that the inception of lightwave optical communication with fiber, the main focus has been on the technology for very 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 need for more bandwidth, the information communication market has risen to the forefront in fiber optic communication. After several rounds of competition along with other technologies, Ethernet is obviously the winner for LAN networks.
Silica-based multimode fiber is adopted to provide a cheap optical link with a mixture of transceivers based upon Vertical Cavity Surface-Emitting Laser (VCSELs). However it is not the very best 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 anticipated to become 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 entire link cost.
But POF possesses its own problems. The most significant obstacle is secondary coating line. PMMA has been used as 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 in excess of 100m.
