Q. |
A fiber which is referred as non- dispersive shifted fiber is? |
A. | coaxial cables |
B. | standard single mode fibers |
C. | standard multimode fibers |
D. | non zero dispersion shifted fibers |
Answer» B. standard single mode fibers | |
Explanation: a standard single mode fiber having step index profile is known as non- dispersion shifted fiber. as these fibers have a zero dispersion wavelength of 1.31μm and so are preferred for single-wavelength transmission in o-band. |
