Advantage of graded index fiber over step index fiber?
A graded index multimode fiber will transmit 800 modes, and has a varying refractive index. A step index multimode will transmit 228 modes.
What is the difference between step index and graded index optical fiber?
1. Step index fiber is of two types viz; mono mode fiber and multi mode fiber. Graded index fiber is of only of one type that is multi mode fiber. 2. The refractive index of the core of the step index fiber is constant through out the core. The refractive index of the core of the graded index fiber is maximum at the center of the core and then it decreases towards core-cladding interface. 3. Number of modes for step index fiber N = V2/2, where V is cut off frequency or normalized frequency or V- number Number of modes for graded index fiber is N = V2/ 4. 4. V number can be less that 2.405 or more that 2.405 for step index fiber V number is always more than 2.405 for graded index fiber. 5. Step Index Fiber is a fiber in which the core is of a uniform refractive index and there is a sharp decrease in the index of refraction at the cladding. Graded Index Fiber is a type of fiber where the refractive index of the core is lower toward the outside of the fiber. It bends the rays inward and also allows them to travel faster in the lower index of refraction region. This type of fiber provides high bandwidth capabilities.
What is the difference between step graded and linearly graded semiconductor p-n junction?
In step-graded the acceptor and donor concentrations in the semiconductor are constants up to the junction.In a linearly-graded junction, impurity concentration varies linearly with distance from the junction
What is meant by step graded junction?
A step graded junction is the pn junction in which impurity concentration does not change abruptly from donor to acceptor but varies smoothly
What is the significance of normalized frequency in optical fiber?
If V is less than 2.405 then the fiber is mono mode but if V is greater than 2.405 then fiber is multimode. V number is also related with the number of modes is the fiber as: N = V2/ 2 for step index fiber and Number of modes for graded index fiber is N = V2/ 4.
How does one create a profitability index?
Profitability indexes are not hard to come by. To create one you must go online to a profitability website in which they have step by step instructions according to the index you need.

Advantages of single step index fiber over multimode step index fiber?
The single step fiber mode tolerates high powered laser use and a high bandwidth in comparison to the multi-step which only allows for non-coherent light sources and lower bandwidth.
What are optical fiber?

What is an Index of Work Satisfaction form?
An "Index of Work Satisfaction form" would be a form used in a survey intended to assess the satisfaction of a work force and to develop a numerical index to describe their aggregate level of satisfaction or dissatisfaction.
How can you boost your math grade up?
Step 1: Ask your teacher when your next Graded Assignmentis. Step 2: Study for it. Step 3: When you complete it, relax. This always works for me in every subject. Good Luck, Me
