Therefore, an alternate optical multiplexing technique, such as OTDM, is the right choice. One of the largest is that multiplexing is only possible with current electrical technology up to roughly 15Gbps. A frame of the ideal size may be communicated in a particular time slot because digital signals are segregated into frames, which are comparable to time slots. Each user is limited to sending data during the allotted time period. The shared channel in TDM is split up using a time slot for the user. Traditional multiplexing methods include Time Division Multiplexing (TDM). The performance of the system degrades as a result of these nonlinear effects. The development of various nonlinear effects such as Stimulated Raman scattering (SRS), Stimulated Brillouin Scattering (SBS), Cross Phase Modulation, and Four-Wave Mixing, is a result of such high powers. Typically, each channel needs roughly 1 mW, and when numerous channels are used, the fiber is pumped with several milliwatts. The emergence of fiber nonlinearities is one such drawback. Notwithstanding the benefits indicated above, there are some drawbacks as well. Consequently, the enormous bandwidth may be used by enabling numerous WDM channels to transmit signals simultaneously on a single fiber. The transmission bandwidth is split into wavelength bands that are non- overlapping. Every particular wavelength in WDM supports a particular communication channel that operates at maximum electrical speed. One of the most suitable methods that are utilized to use the enormous amount of accessible bandwidth of the optical fiber is wavelength- division multiplexing (WDM). In optical networks, data transmission can be primarily accomplished through the use of time and wavelength division multiplexing. Several intriguing methods, including signal multiplexing techniques such as wavelength division multiplexing, frequency division multiplexing, code division multiplexing, and time division multiplexing, have been developed. Even if the maximum data rate for commercially available electrical components is 10 Gbps, there is still a chance to increase the system data rate by using other multiplexing techniques. Broadband communication services are becoming more and more in demand, necessitating telecommunication networks with line capacity much in excess of those of the available facilities. There has been an unstoppable demand for fast, highly efficient network systems that can make use of the current optical fiber lines. Throughout the previous generation, optical fiber communication has advanced significantly along with the invention of new components to increase capacity.
