Abstract

Nowadays the implementions of the transmission modulation techniques (high channel capacity) in optical fibres have been widely developed, one of the successful key factors of this system is the application of digital modulation techniques and the adjustment of modulation pattern. Modulation pattern of adjustment measures on the operational requirements of the system was made possible by the utilization of techniques Apol RZ-DPSK (Alternate Polarization Return-to-Zero Differential Phase Shift Keying). It is considered likely because it can reduce the effects of inter-channel non-linearity, noise and simultaneously demonstrates increasing system margins.

Abstract

The increasing demand for telecommunication services nowadays, particularly in optical fiber transmission, has necessitated the optimization of optical amplifying device, such as Erbium Doped Fiber Amplifier (EDFA). The latest development of technology has enabled the implementation of Raman Amplifier in the long haul system (300-800 km) and ultra long haul system (>900 km). The Raman Fiber Amplifier (RFA) is recommended for several advantages, such as flat gain for all wavelengths, low noise figure, and applicable to any kind of optical fibers. It is quite possible that by using C + L Band approach, much higher raise in the band Hybrid EDFA/RFA’s amplification factor can be achieved. Keywords : Optical Amplifier, EDFA, Raman Fiber Amplifier (RFA), Hybrid amplifier, Noise Figure, Gain, Optical Communication.

Abstract

Sequencing techniques Deoxyribonucleic Acid (DNA) at this time is a method to identify the genetic basis of living beings, including to determine the accurate genetic relationship of several DNA sequence data. Kinship clearly and easily can be expressed in the form of a phylogenetic tree diagram (Phylogenetic Tree). This diagram represents kinship obtained from the elektroferogram process of electrophoresis sequencing of DNA bases. From some sequences experimental results using sequence analysis application program gradually, starting from installing, editing, and alignment so as to obtain the analysis and phylogenetic branching diagram view. This study uses a sequence analysis program Mega-7 (Molecular Evolutionary Genetics Analysis) to obtain a phylogenetic diagram for high accuracy and relatively easy to operate. This program can translate image data into nucleotide bases that shows the kinship of the distance the nearest branch with a standard sequence. The major advantage of this program is that it can do some analysis in a single program.

Ultra long distance transmission systems - Dense Wave length Division Multiplexing (U-DWDM) is one of the fiber optic transmission systems are designed to provide large capacity and is able to transmit long distance range. Technology system design is made possible by simplifying the network architecture, as well as involving large-capacity network level, such as the use of a single network of 10 Gbps to 40 Gbps, increasing the number of wavelengths, as well as reducing the wavelength interval to extend the range of spectral systems (C-band L-band S -band). So the U-DWDM system design is a breakthrough fiber optic transmission system which is able to raise up to 160 wavelength.

Abstract

                                                                    Abstract Optical fiber transmission is generally used when the channel capacity (40 Gbit / s). Some of the key factors in achieving successful performance of this system include the implementation of Apol-DPSK modulation technique (Alternate Polarization Return-to-Zero Differential Phase Shift Keying), which accurately able to power up the canal, placement of optical amplifier (repeater) is recommended to increase the transmission range (the average gain for the entire wavelength range, low noise figure) and the use of optical fiber characteristics. To complement performance optical gain is selected fiber types NZDSF (Non-Zero Dispersion shifted fiber), it certainly can provide significant gains at the same time to reduce the widening pulse narrowing occurs due to chromatic dispersion and non-linear fiber effects.
