Investigation of Modulators in OTDM system

With the ever-increasing demand for higher speeds and larger capacity brought about by rapid data growth on the Internet, interest in optical time division multiplexing has been growing rapidly in recent years due to its high speed and ability to overcome the “electronic bottleneck” offered by today’s electronic components. Optical time division multiplexing (OTDM) transmits multiple data channels in the form of ultra-short duration optical pulses which are interleaved into a single high-speed data stream by accurate control of their relative delay in the time domain. OTDM transmission system has been a topic of continuous research due to their unique advantages over conventional Pulse sources based transmissions. Among various key high repetition rate, limited pulse source, pulse range still remains as the issues that require further optimization. The performance of OTDM system is analyzed by using BER analyzer in which Q factor is to be measured. In OTDM system the maximum Q factor can be achieved by using different methods which are increasing laser power, using various.. We will focus on performance metrics and parameters used in the topology. We also focused on various modulators related to the topology.
