In order to improve the performance of fiber network, not only higher quality factor and minimum bit error rate required but also the role of ER cannot be neglected. Since, only the treatment of linear and nonlinear impairments are not sufficient, there must be a need of degradation of signal leakage through the optical fiber networks related to th...

Plasma is a set of neutral and charged particles which reveals a number of collective behaviors. The very long range coulomb forces enable the charged particles in plasma to work together with one another simultaneously. The study of plasma is actually a really ancient area of investigation in plasma physics and it remains to be among the vital fie...

Fiber optic technology with the role of surface plasmons has tremendously advanced the sensing technique of various physical, chemical and biochemical parameters of materials. The working of the optical fiber sensor designed by us is founded on the principle of the absorption of the evanescent waves passing through the optical fiber. The technique...

Good potential uses in fiber and fiber lasers have been seen through Random Fiber Gratings (RFGs). However, a quantitative link has never been studied between the RFG's randomness and spectral reaction. This paper first experimentally characterizes two RFGs of varying degrees of randomness by optical frequency reflectometry (OFDR). The high degree...

It emphasized on the role of Extinction ratio in order to manage loss in long haul optical Fiber Transmission with EDFA and DCF

In the fiber optic communication network for example,-FTTH, EPON, NBN, OTN and so on, the most important components are fiber length between transmitter and receiver point. So, to make, cheap and meaningful communication through optical fiber it must be required to calculate how and what amount of signal is transmitted with the given length of the...

Self-sustained models related with generating three dimensional dynamical systems results to multi equilibria, periodic, quasiperiodic and chaotic trajectories, with no external forcing mechanism. The simpler models just show the results without the direct connections with the natural events. In nature there are number of systems that can be govern...

The optical signal is transmitted by the transmitter and travel through the fiber of length either short as a few kilometers (KM) or as long as transatlantic distance and then arrived at the receiver end. That is the channel between transmitter and receiver is the most important part of the optical fiber networks like LAN, FTTH, EPON, NBN, OTN etc....
