Optical Fiber: The New Era of High Speed Communication (Technology, Advantages and Future Aspects)

This paper deals with the Basic communication model and the types of fibers for the optical fiber communication system. Then the different technologies in optical fiber communication along with their features are discussed briefly. Some comparisons of optical signals with the traditional electrical signals are explained concisely. Finally the general system of optical fiber communication is bri...

Titanium Welding Technology

In order to establish titanium welding technology TIG arc weldability and MIG arc weldability were surveyed. For TIG arc weldability influence of arc length and thickness to proper region of welding condition became obvious. For MIG arc weldability a new method to defend wandering phenomenon was developed.

Arc Shape Characteristics with Ultra-High-Frequency Pulsed Arc Welding

Arc plasma possesses a constriction phenomenon with a pulsed current. The constriction is created by the Lorentz force, the radial electromagnetic force during arc welding, which determines the energy distribution of the arc plasma. Welding experiments were carried out with ultra-high-frequency pulsed arc welding (UHFP-AW). Ultra-high-speed camera observations were produced for arc surveillance...
