Abstract

Objective: Optical fibers are the fastest way to transmit the data or information from one place to another without any loss of data. Optical fibers are evolving since their invention, and hence number of researchers is currently working on its evolution Findings: This paper proposed a new approach in Optical Time Division Multiplexing (OTDM) at 240Gbps by incorporating using three different approaches. Different approaches consisting of transmission employing ReturnZero (RZ) transmitter for all time delayed signals, Non Return-Zero (NRZ) for signal and finally hybrid configuration Return-Zero to Non Return-Zero (RZ-NRZ). Hybrid technique is carried out to reduce crosstalk and interference among time multiplexed channels. Methods: The variety of experiments has been carried out under the controlled simulation environment with the help of optic system results reveal that very less crosstalk found in hybrid configuration. Proposed system is designed in such a way that it is capable to support 240gbps Optical Time Division Multiplexing (OTDM) over 180 km with acceptable bit error rate. Applications: The proposed technique is based on hybrid model and hence easily able to meet the huge demand for higher capacity and larger bandwidth, this system is able to provide high speed transmission.
