Q. |
When more than one mode is propagating, how is it dispersed? |
A. | dispersion |
B. | inter-modal dispersion |
C. | material dispersion |
D. | waveguide dispersion |
Answer» B. inter-modal dispersion | |
Explanation: when more than one mode is propagating through a fibre, then inter modal dispersion will occur. since many modes are propagating, they will have different wavelengths and will take different time to propagate through the fibre. |
