Explain about the double-crucible method.
Low loss fibers are mostly manufactured by using double crucible and vapour phase deposition method.
The double-crucible method is the mainly common direct melt procedure. The double-crucible process combines the molten rods in a single perform by using two concentric crucibles. Optical fibers are drawn by this molten glass by using a same fiber drawing process as into vapor phase oxidation. A demonstration of a fiber drawing apparatus by using the double crucible process is illustrated in the given figure.

Q. Geosynchronous Orbit Communications satellites are able to be placed in equatorial orbits at a distance which results in an orbital period of one day. Therefore the satellit
What are the concepts of distance and displacement?
Indicate all that is incorrect about the statement The magnetic field lines of a stationary bar magnet move from the north pole of the bar magnet to the south pole of the bar magne
FACTORS AFFECTING INDUCED EMF By experiment, the following factors may be noted: • The faster the magnet (or coil) is moved, the greater is the deflection obtained on the meter
Q. When the negative feedback is practical to an amplifier of gain 50 the gain falls to 25. Compute the feedback ratio? Af = A / 1 + Aβ 25 = 50 / 1 + 50 β 1 = 2 / 1 + 50
A transformer takes a current of 1A when its primary is connected to a 300V, 50Hz supply, the secondary being on open-circuit. If the power absorbed is 120watts, Determine
