SYSTEM DESIGN FOR COARSE WAVELENGTH DIVISION MULTIPLEXING

摘要

Present invention provides specially a system design for Coarse Wavelength Division Multiplexing. This system focuses on design of Integrated Circuits (ICs) based transmitter and discrete components based receiver circuit for Coarse Division Multiplexing (CWDM) system. This hybrid design have been used to increase the QoS parameters such as cost, output signal power, insertion losses, isolation losses and link budget of the system.Following invention is described in detail with the help of Figure 1 of sheet 1 showingblock diagram of CWDM system, Figure 2 of sheet 1 showing the circuit diagram of CWDM transmitter using IC-HK and IC-WK and Figure 3 of sheet 2 showing circuit diagram for CWDM receiver.
