Abstract:Multiplexing is an essential part in a communication system. It is widely employed due to increase transmission capacity and to reduce system costs. There are three basic types of multiplexing technique in communication systems; time division multiplexing (TDM), frequency or wavelength division multiplexing (FDM) or (WDM), and code division multiplexing (CDM). In this paper, wavelength division multiplexed optical communication system is designed based on different duty cycle. The design is proposed for 10-users and data rate is 2×100 transmitted up to 78 km using SSMF.
Abstract:Multiplexing is widely employed due to its capability to increase transmission capacity and to reduce system costs. The system features multiplexing of the basebands in electrical domain as well as multiplexing in optical domain (WDM). The design is proposed for 10-users, each one assigned a different RZ duty cycle and with a data rate of 20 Gbps. In this work, optical wavelength Division Multiplexing is done on wavelengths 1550nm and 1552nm. There are two modulation schemes AM and MZ are compared for 2×100 Gbps Based WDM Optical Network. The AM shows better performance as compared to MZ modulation scheme, AM transmitted successfully upto 78km where as MZ up to 75km.
