In this example, we will demonstrate how INTERCONNECT can be used to design and simulate an optical transceiver.

An optical transceiver is a single, packaged device that works as a transmitter and receiver. It is an important part of optical network equipment that converts electrical signals to optical signals and vice versa. The data flow simulator of INTERCONNECT allows for time domain simulations, where each data is a time stamped signal sample. Now you can simulate time domain impairments such as intersymbol interference. The circuit below shows an externally modulated NRZ transmitter and a direct detection receiver using a PIN photodiode:
To simulate a transceiver in INTERCONNECT we can start by creating the transmitter and receiver modules using the elements from the Element Library (connecting the elements and setting their properties). INTERCONNECT allows you to perform signal integrity analysis in the transmitted and received time domain waveforms using different types of analyzers, such as oscilloscopes and spectrum analyzers.
