Optical Fiber Communications: Principles and Practice

Design And Implementation A System Communication Of Optical Fiber By Using Interval Wavelength (532nm-820nm) Of Diode Laser

“…The output optical power is increased as the injection current increase but a low output power achieved below the threshold point until the current reached to the threshold where the laser action start and above the threshold a great change in the output optical power with a small change in injection current is obtained [2].…”

“…A block diagram of the fiber optics communication system is shown in figure (1). [2] Optical fiber is the most common type of channel for optical communications, however, other types of optical waveguides are used within communications gear, and have even formed the channel of very short distance (e.g. chip-to-chip, intra-chip) links in laboratory trials.…”

“…The need for periodic signal regeneration was largely superseded by the introduction of the erbium-doped fiber amplifier, which extended link distances at significantly lower cost. [2] II.…”

Dispersion Compensation in Optical Communication Link Using Apf’s

“…Due to the presence of chromatic dispersion the light pulse carrying the required information is spread into various components and each component travel differently along the optical fiber with different velocity and hence reach at the receiver at different times which distorts the information and can't be interpreted in the correct manner This is called group velocity dispersion (GVD) which cause the light pulses to spread in fibers, degrading signals over long distances [8][9][10][11]. In order to remove the spreading of the optical or light pulses, the dispersion compensation is the most key feature required in optical fiber communication system.…”

Comparison of Chromatic Dispersion Compensation Method Efficiency for 10 Gbit/S RZ-OOK and NRZ-OOK Wdm-Pon Transmission Systems

“…While transmission speeds and service coverage areas increase, wireless network operators are still unable to provide sufficient transmission speed and quality as fibre-optical connection can. There are a number of compelling advantages for using fibre-optics, for example, fibre-optic cabling provides a much higher bandwidth, fibre-optics do not suffer from intersymbol interference and have much lower levels of signal attenuation [1].…”
