hai... actually in optic fibre singlemode means single core....multimode means multiple core...so what about data sending paths.... in single mode data will be transmitted and received in same single core or what.....just i wnat to know the same thing for multimode also(brief explanation please).....thanks in advanz.....

Huh? You lost me. What is your question?

hai....actually my qustion is, in single core data will pass through that one core only(means transmitting and receiving will be done in same core ),then how the process will happen if it is an multimode(multicores).thanks in advanz.

There are two types of multimode fiber, step index and graded index.

In both types of multimode fiber, the rays of light are reflected back into the core by the cladding boundary.

In step index fiber, the light is relected back at sharp angles, while in graded index fiber, the light is reflected back in a range of less sharp angles.

Graded index fiber has less multi-path dispersion than step index fiber.
