Optical Communications: Optical OFDM Transmitter (100 Gbit/s)
In wireless systems such as wireless local area network (WLAN) and in electrical wireline systems like digital subscriber line (DSL) Orthogonal Frequency Division Multiplexing (OFDM) has become an important technology. OFDM for optical communication systems is a great challenge because of high data rate of 10 Gbit/s and beyond. In this area application of OFDM has become an important research topic.
To design a high speed OFDM transmitter we describe the digital logic in the hardware description language VHDL and by simulations of the whole optical communication system, including fibre and other components which are designed in C++, we can study the effect of channel impairments and noise.
A transmitter prototype using an FPGA was already successful built which can reach a data rate of over 10 Gbit/s. The experimental setup is shown on the figure below.
In a research project we are studying much higher data rates towards 100 Gbit/s and beyond.
