“…First, in order to evaluate the all-optical connection FSO system characteristic, the result of the 10 Gbps single wavelength light signal transmission experiment [Arimoto 2007] which is not achievable with conventional FSO system is shown in Figure 19. The bit error rate (BER) is measured by accumulated at 1 minute interval is shown in the figure.…”

“…This is because of the fluctuation of the beam angle-of-arrival (AOA) which in turn leads to significant variation in the power of the light focused into the SMF. It therefore becomes difficult to maintain an error free communications link due to the received signal power occasionally dropping below the receiver sensitivity [26].…”

Free-space optical communication has emerged as a competitive and viable technology for offering high data rates, improved capacity, cost-effective and an easy to deploy solution for providing connectivity between two points which are up to a few kilometers apart. In this paper we present experimental work which demonstrates the practicality of next generation free-space optical (FSO) communication systems suitable for short-haul, high-speed and robust data links. This experimental system is placed between two buildings in the Waseda University campus area for a communication link spanning a distance of 1 km.We outline the design of the optical antenna which uses 1550 nm wavelength and directly coupling a freespace optical beam to a single-mode fiber without the need for OE/EO conversion, to offer a communication link with data rates from 2.5 Gbps to 10 Gbps. The antenna is capable of overcoming most common limitations inherent in FSO communication systems, such as atmospheric induced beam wander and scintillation effects. A high-speed tracking mechanism which utilizes a fine positioning mirror (FPM) capable of tracking and controlling the received beam and focusing/steering most of beam power into the fiber is presented. This FPM is capable of suppressing the frequent power fluctuations caused by beam angle-of-arrival (AOA) variations. This paper presents experimental results of the FSO communication system capable offering stable performance in terms of measured bit-error-rate (BER). Performance results showing increasing the systems data rate from 2.5 Gbps to 10 Gpbs are also presented.

To provide multi-gigabit free-space laser communications to spacecrafts and mobile users on aircrafts, ships and trains, a small and light-weight laser communication terminal have been developed at NICT. The terminal provides seamless connectivity between optical wireless network and fiber optic network by using fast and accurate bidirectional beacon tracking which has been originally required for optical intersatellite communications. This paper shows the performance of the newly developed terminal and the results of demonstration experiments over terrestrial horizontal link under heavy atmospheric turbulences.
