Passive optical networks (PONs) are more proficient to meet the demand of huge bandwidth and high capacity technologies in optical communication system. PON is point to multipoint networks and also enhances the network efficiency and reduces network termination cost. In this paper, we compare the performance and operational difference of proposed bidirectional broadband passive optical network (BPON)...
Higher data rate transmission over longer distances is the need of this era where a huge number of communication users are being added up on a daily basis. This is not a easy task due to presence of fiber impairments which are of two types linear and non-linear. Dispersion occurs due to longer distances and high transmitting power of the light signals which ultimately degrades the received signal...
The need for higher bandwidth along with lesser power and reduced losses are some of the great reasons behind the innovation of optical fiber. Although optical fiber has great efficiency itself but it also accumulates some of the losses like that of linear and non linear losses which are directly linked with the magnitude of the transmitted power. There are two ways of reducing the optical impairments,...
With the advancements in communicating equipments, protocols-standards and software, optical fibers are also upgrading with course of time. MetroCor fiber has a low negative dispersion as well as small dispersion slope which enables this fiber to be more efficient than Single Mode Fiber (SMF). At smaller transmitting power the fiber is known as linear whereas on increased power levels non-linear state...
Optical fibers are used in this era with the expectation of transmitting very high data rate at longer and longer distances, for this to be in practically implemented dispersion compensation techniques are used like that of pre, post and symmetric compensation. This paper focuses on the application of fibers at extended distances without using dispersion compensation techniques, the most vital part...
When optical fibers are dealing with small power then the state of fiber is known as linear and when there is increase in power then the optical fiber is prone to non-linear effects. Self-Phase Modulation (SPM), Cross Phase Modulation (XPM), Four Wave Mixing (FWM), Stimulated Brillouin Scattering (SBS), Stimulated Raman Scattering (SRS) are one of the common non-linearities in fibers. This paper focuses...
This paper analyzes single- and double-zone junction termination extension (JTE) structures for 4H–SiC Schottky diodes using numerical simulations. In the single-zone case, we study the effects of JTE dose, depth, length, metal/JTE overlap length, and surface or interface charge. In the double-zone case, we systematically vary the inner and outer doses over about 80 possible combinations for each...
