What is splicing?
Splicing:
Two optical fibers utilized for communication are joined with a process termed as Splicing. This must be done very carefully that is the splicing process does not introduce additional losses. Two methods in splicing are there:
In the first process, the two ends of the fibers are fused. Within the second method, the two ends are aligned and bonded together by using an adhesive.
A weakly guiding optical fibre propagates just two bound modes with scalar transverse electric fields ψ 1 (x,y) and ψ 2 (x,y), and propagation constants β1 and β2, respectively. At
In an electric field rate of change of potential with distance is called as potential gradient. It is a vector quantity and its direction is differing to that of electric field. Po
The mass of 1 mole of electrons is: (1) 9.1x 10 -28 g (2) 1.008mg (3) 0.55mg (4) 9.1x 10 -27 g Ans: (3)0.55mg
A 2350-kg granite tombstone absorbs 2.8 x 10 7 J of energy from the Sun to change its temperature from 5.0°C at night to 20.0°C during an autumn day. Verify the specific heat
WHY Surface tension increases when an highly soluble SUBSTANCE is dissolved in water WHILE IT DECREASES WHEN an weakly soluble substance is dissolved in water
What are intrinsic and extrinsic semiconductors? A semiconductor is a material that has an electrical conductivity among that of a conductor and an insulator. In a semiconducto
(1) Standing pulse can be longitudinal / transverse. (2) The disturbance confined to a particular part among the starting point and reflecting point of the ray. (3) There is
A 40 kilogram girl climbs a vertical distance of 5 meters in twenty seconds at a constant velocity. How much work has the girl done? Ans: 2000 joules or 1960 joules work is
For an object moving in uniform circular motion, the direction of the instantaneous acceleration vector is: w) tangent to the path of motion x) equal to zero y)
