The goal of this project is to design and analyse a radio over fibre system for a four-story hospital with 20 rooms on
each floor. The number of ONUs per floor is 20, and it was assumed that each room had an ONU capable of providing network
access to voice, data, video, and biometrics. We build an 80-channel WDM optical transmitter using the WDM method. The
proposed system includes a transmitter with 20 input channels, a multiplexer, a DE multiplexer, a 45-kilometer optical fibre, and
an amplifier.
