3.3 DEMERITS
Cost comes first in 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 system which add cost and manpower. It is also susceptible to physical damage despite of being flexible. It cannot hold high stress and is likely to break. It is more fragile than copper. When fiber breaks it requires careful …show more content…
These waves are then carried via optical fiber and on reaching the destination site they are demodulated by optical detector (photodiode, phototransistor, photoconductor etc.) to produce electrical output signal.
The telecom industry uses fiber optic cable to establish communication between different exchanges such as MSC (Mobile Switching Centre) to BTS (Base Transceiver Station) and between MSC’s as well. Also, it is being widely used instead of Microwave Link to form the trunk network and to provide high speed broad band internet by the ISPs (Internet Service Provider). It forms the connection between different servers, sever to APs and APs to subscriber modules as well. Google fiber is one of the best examples of application of fiber optic in broadband connection where the internet speed of up to 1 Gbps is achieved (hundred times faster than the normal broadband connection) (Google fiber, …show more content…
The common point on all these application is how the light pulses (photons) and their properties are being used. In communication field, the amplitude and frequency of light represented the data being transmitted while in manufacturing industry its light weight, flexibility, information carrying capacity became prime concern. And finally coming to optical sensors the changes in the properties of light (intensity, wavelength, polarization) being carried provided the measurement of physiological and different parameters. In all sectors of application the EMI resistant property of fiber has been a motivating factor for more innovations of optical fiber equipment and its increasing
