Question

What modulation scheme allowed optical fiber communications to become possible?​

Answer 1

Answer:

The mixing of analogue and digital communication like Amplitude modulation, Frequency modulation, differential phase shift, offset quadrature phase-shift keying amplitude modulation and frequency phase modulation are applied on different optical communication systems to further enhance the parameters like BER, Q factor

Answer 2
