The answer is False.<\/p>\n
Modal noise is a type of noise that occurs in optical fiber transmission systems. It is caused by the different modes of light that can propagate through the fiber. The different modes of light have different propagation speeds, and this can cause interference between them. This interference can lead to signal degradation and loss.<\/p>\n
Digital transmission is less likely to be affected by modal noise than analog transmission. This is because digital signals are represented by a series of discrete pulses. These pulses are much shorter than the wavelength of light, and this makes them less susceptible to interference from modal noise.<\/p>\n
Analog signals, on the other hand, are represented by a continuous waveform. This waveform can be much longer than the wavelength of light, and this makes it more susceptible to interference from modal noise.<\/p>\n
In conclusion, digital transmission is less likely to be affected by modal noise than analog transmission. This is because digital signals are represented by a series of discrete pulses, which are much shorter than the wavelength of light. Analog signals, on the other hand, are represented by a continuous waveform, which can be much longer than the wavelength of light.<\/p>\n","protected":false},"excerpt":{"rendered":"
