| 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. | |
