According to number of modes optical fiber are classified into two types One is i singlemode optical finer and other is ii multimode optical fiber i Singlemode optical fiber A singlemode optical fiber is designed to carry only a single mode of light the transverse modeThe diameter of this type of fiber is relatively low about 83 to 10 microns and it operates at wavelength of 1310nm and 1550 nmThis type of optical fiber has less degradation of signal low dispersion and well suited for long distance    See Answer
