This blog is dedicated to Orthogonal Frequency Division Multiplexing. It starts with Basics of OFDM and then it moves towards Contribution of OFDM in Optical fiber Communication.
OFDM subcarriers are closely spaced, orthogonal and used to carry data.
Data is divided into parallel data streams each transmitted on a separate subcarrier.
Each sub-carrier is modulated with a conventional modulation scheme (QAM or PSK) at a low symbol rate
