Optical fiber thin as hair is everywhere on this planet, carries an enormous amount of information from place to place. There are a number of desirable characteristics of the optical fiber for conveying this information. They have the ability to carry large amounts of information, a low cost and have the immunity from electrical wiring and wireless communication link a number of disturbances that can afflict. Advantages of optical fibers for transmitting information from place to place, it replaces its fast, has led to older technology. Optical fiber, and plays an important role in enabling the abnormal growth of global communication that occurred in the past 25 years, it has it is essential to be able to proliferate and use of the Internet.…
The core of an optical fibre is the centre of the cable where the thin glass strands that transmit the light are. This can be made out of plastic or really pure glass depending on the quality of the wire. The glass that the light will travel through can’t have any impurities in it because this will cause dispersion and attenuation for the light traveling down the wire which would decrease the signal strength. The light travels down the core through the process of total…

What is Fiber Optic Cables?
Back in the day we used copper wires for our tele-communication and to interconnect throughout the world. However as technology and machines start to grow more powerful, we are forced to put a change in this production of copper wires. The wire density becomes a very critical factor in the modern era, however the limit in size must always result in better performance. Fiber optics proves to be highly effective in its high bandwidth, as it allows on a single fiber to…
Fiber optic communication systems are light wave systems that employ optical fibers for transmitting information from one point to other through an optical fiber. The driving force behind the widespread use of fiber optic communications is the demand for economic, reliable transmission media that can transmit required information capacity. The transmission capacity of optical fibers has drastically improved over the years. Today, optical communications up to 100 gb/s for several kilometers have…
considering the demerits of optical fiber networks. Despite of the fact that the cost for fiber is dropping by 60% per year and is beneficial in long run, its initial installation cost is still high and is not affordable to all vendors. Per unit cost of fiber cable is more than that of copper cable.
Secondly, as the technology is still new and improvising, it requires skilled manpower for its installation, operation and maintenance. Further it requires new equipment compared to prevalent…

Spinning of Nylon Fiber:
The turning of the nylon filaments is completed with dissolve turning. There are two strategies for liquefy turning:
1. Grid turning
2. Extruder turning.
Lattice turning is utilized for the generation of better fibers. The nylon chips are made to fall on a hot matrix that melts the nylon pieces. The liquid nylon is pumped through a sand channel to the spinneret. The sort of fiber created relies on the quantity of gaps on the spinneret, the size and the state of the…
