Abstract

The use of transparent free-space optics (FSO) allows the adoption of DWDM transmission enhancing the capacity of optical wireless link exploiting the full capacity of optical fibers. 40 Gbps data rates were obtained by time-multiplexing four 10 Gbit/s electrical sequences with a pattern length of 2. On field test on a real 60 m long transparent FSO link was performed so two devices to allow the necessary movements of the fibre and the lens series were assembled. An error free conditions with BER and Q factor measurements up to 40 Gb/s, for different interference power level, has been achieved. The achieved experimental results show that transparent FSO technique has the ability to provide high bit rate transmissions in the last hundred of meters.
