Analysis of duo-binary modulation scheme in single channel on the basis of BER

The demand for high speed data transmission is increasing so as to fulfil the demand of high speed the Duo-binary modulation Format is used. Hence this paper deals with the duo binary modulation technique in the optical single channel system at different fibres lengths and data bit rate. While increasing the length and data rate of the transmitter the bit error rate changes simultaneously. The demand for the high bit rate data transmission is increasing and thus easily accomplished.
