The variant of non-zero-dispersion-shifted fiber is called as __________

a) Dispersion flattened fiber 
b) Zero-dispersion fiber 
c) Positive-dispersion fiber 
d) Negative-dispersion fiber




Answer : - Negative-dispersion fiber

The dispersion profile for non-zero dispersion shifted fiber is referred to as bandwidth non zero-dispersion-shifted fiber. It was introduced to provide wavelength division multiplexed applications to be extended into the s-band. The variant of non-zero-dispersion-shifted fiber can also be referred to as dispersion compensating fiber
